THE CASE FOR OUR COSMIC ANCESTRY
New data signals a major paradigm shift in science
by Chandra Wickramasinghe

How did life arise? Not just on the Earth, but anywhere in the Universe? Does life emerge on every Earth-like planet that have oceans and an atmosphere by spontaneous processes involving well understood laws of physics and chemistry? Or did it involve an extraordinary, even miraculous intervention?
How old is the universe itself? How did it originate, if it indeed did ever originate? Is there evidence of life outside the Earth? In comets, the space between stars in our Milky Way galaxy, on other planets, in other galaxies? Science must necessarily exclude miraculous options of course, but the questions continue to be asked and demand answers. Many of these questions have an antiquity that predates Western traditions that go back to classical Greece in the first century BCE. The answers may have a genesis that goes outside the realm of Western culture. The concepts of zero, infinity (Ananta) all have an Indian origin and are inextricably linked with Hinduism and Buddhism. It could well be for this reason that the idea of an infinite universe has been so forcefully resisted in Western science!
In the past six months many strongly-held opinions in science have been challenged by the arrival of new data. We may be now ever closer to finding answers to the age-old questions to our cosmic ancestry and the origin of the universe.
The James Webb Space Telescope (Webb) launched in 2021 is the most powerful astronomical observatory surpassing the range and capabilities of the earlier Hubble Space Telescope. It was designed to see deeper and further into our origins: from the formation of stars and planets, to the birth or possible birth of the Universe itself. Webb is an international partnership between NASA, ESA and CSA.
Discoveries using the new James Webb Telescope have shown the existence of galaxies that are much older than the age of the currently fashionable Big Bang model of the universe itself – a universe which is just 13.8 billion years old, barely three times the age of the Earth.
This unimpressive smudge of light called CEERS-93316 (Fig.1) was observed by the James Webb Telescope and is presumed to be the most distant galaxy at a distance of about 35 billion light years. This latest discovery, amongst others, lend support to ideas of a steady-state universe with an infinite age, or models of the cosmos involving alternating phases of creation and destruction. These emerging models of the cosmos are remarkably in agreement with ancient Vedic, Hindu and Buddhist ideas.
Another equally important paradigm shift that is happening now relates to the question of the origin of life, and the connection between life on Earth and the wider universe. The Kepler Orbiting Telescope in launched in 2009 was dedicated to discovering habitable Earth-like planets in our galaxy outside the solar system. A large number of such habitable planets have been discovered so far, and a few weeks ago the James Web Telescope was deployed to study one of these exoplanets in some detail.
This “Earth-twin” known by the name K2-186 is located some 120 light years from the Earth. The surprising discovery was a molecule called dimethyl sulphide, along with carbon dioxide and methane, in the atmosphere of K2-186 that has been hailed as definite evidence of extraterrestrial life. The argument hinges on the fact that the molecule dimethyl sulphide appears to be only produced by biology on the Earth – by marine plankton in particular. So rather belatedly scientists have accepted that a second living planet exists 120 light years away from the Earth. So, the outstanding question now is how and by what processes did life originate on this planet? Or indeed on any other planet?
The long-held view (going all the way back to Aristotle in the third century BCE) is that life emerged and emerges easily and “naturally” on a planet like Earth (or on K2-186, for that matter) as soon as the “right conditions” prevail. The modern version of this concept that has been defended from the dawn of the 20th century is the so-called “theory of spontaneous generation”. Without any substantive proof for it and a great deal of contrary evidence this concept remains part of the holy grail of biology.
According to this theory of spontaneous generation organic molecules in the Earth’s oceans are supposed to assemble themselves naturally into primitive living systems that subsequently evolve over billions of years to produce the magnificent panorama of life of which we form the most trivial part. Needless to say, there was never any substantive evidence to support this point of view, but nevertheless it was one that has been accepted by the entire establishment of science, more or less like an act of faith.
Experiments to “prove” the process if spontaneous generation and to synthesize life from non-life have continued to be conducted in the most advanced biotechnology laboratories across the world for well over half a century. Every attempt that has been made to replicate the process of spontaneous generation in the laboratory under the widest possible range of conditions has ended in dismal failure. The reason is simple: the probability hurdle needed to go from non-living organics to the simplest evolvable living system is of a scale that is super-astronomical. The origin of life requires a system that transcends the scale of the Earth, our solar system, our Milky Way Galaxy and perhaps involves the entire universe, that is now appearing to be possibly infinite in scale.
The alternative to spontaneous generation of life is the concept of life being a cosmic phenomenon or panspermia as it has come to be called. This basic idea has an antiquity in Western tradition that predates Aristotle and is attributed to the pre-Socratic philosopher Anaxoragas. Anaxoragas suggested that the seeds of life are all pervasive in the cosmos and they take root and develop into living entities whenever the right conditions prevail. This is the theory of Panspermia (from Greek roots: Spermata – seed; Pans – everywhere). Similar ideas are implied in Buddhist, Hindu and Vedic cosmologies and of course these predate the ancient Greeks by many centuries.
From the 1970’s onward the late Sir Fred Hoyle and the present writer became torch bearers for the theory of cosmic life which was a revived form of the ancient theory of panspermia. The starting point in our investigations involved the identification of cosmic dust, the trillions upon trillions of micrometre-sized “dust” that makes up a few percent of the mass of the entire Galaxy, and shows up as conspicuous dark clouds and striation against the background of stars in the Milky Way. By 1984 we had accumulated enough astronomical evidence to conclude that a very large fraction of this cosmic dust in fact linked to life – bacteria and viruses in various stages of decay and degradation, but still largely preserving the information required to initiate life on any habitable Earth-like planet.
Case against spontaneous generation of life
The most powerful single argument for life being a cosmic rather than a purely terrestrial phenomenon was articulated by the late Sir Fred Hoyle way back in 1980, summarizing the position that we had reached at the time:
“The very small probabilities, which one calculates for the assembly of these substances (e.g. enzymes), demonstrates as near to certainty as one would wish that life did not originate here on the Earth. Indeed, the infinitesimal probabilities demonstrate that life is even too complex for its origin to be confined within our galaxy alone. The resources of the whole universe were almost certainly needed……”
If there was a deep principle of nature that drove inorganic systems towards the emergence of primitive life – the evidence for this would have long since been discovered in the laboratory, which as we noted, has not. Moreover, with calculations showing grotesquely low a priori probabilities for the transition from non-life to life only two options remain: –
(1) The origin of life was an extremely improbable event that must have occurred on Earth against all odds (because we are here!) but will consequently not be reproduced elsewhere. In that case we would indeed be hopelessly alone as a life system in the Universe.
(2) Alternatively, a very much vaster cosmic system than was available on Earth, and a very much longer timescale was involved in an initial origination event, after which life was transferred to Earth and elsewhere by processes that the late Sir Fred Hoyle and the present writer proposed many years ago – cometary panspermia.
We then went on to argue that this cosmologically-derived legacy of life, along with its full evolutionary potential (contained within the genomes of bacteria and viruses), were distributed mainly by comets and other repositories of cosmic dust onto habitable planets like the Earth. Comets in this theory are incubators and distributors of the information of life throughout the universe in the form of bacteria and viruses.
Whilst in 2023 comets are conceded by most scientists as being the repositories of complex organic molecules that may have contributed to spontaneous generation of life, their role as carriers of life itself, despite an ever-increasing body of contrary evidence is still fiercely resisted. Hard evidence of comets containing organic molecules that can only reasonably be derived from biology are coming in fast and thick. The Rosetta Space Mission to a comet – Comet 67P/C-G – launched in 2013 has yielded a formidable body of evidence, all showing consistency with the existence of microbial material in comets.
Another comet, Comet Lovejoy, has more recently been observed and found to be emitting large amounts of ethyl alcohol as well as a type of sugar into space – equivalent to 500 bottles of wine per second. These are the natural products of fermentation, which is clear evidence for sub-surface microbial activity in a comet.
Are cosmic bacteria continually falling to Earth?
One crucial test of the theory of cosmic life is to probe the stratosphere for in-falling alien genetic systems – bacteria and viruses. To urge international space authorities with the capability of doing this was far from easy. The first dedicated effort to test the idea of bacterial in-fall from comets was carried out in collaboration with scientists at ISRO (Indian Space Research Organisation) in 2001.
Positive detections of in-falling microbiota were made, and the number of bacterial cells collected in a measured volume of the stratosphere at 41km led to an estimate of an in-fall rate over the whole Earth of 0.3-3 tonnes of microbes per day. This converts to some 20-200 million bacteria per square metre arriving from space every single day.
Very recently microorganisms were discovered on many occasions between 2013 and 2017 on the outside of the International Space Station that orbits at 400km above the Earth. There is no easy way to maintain that such microorganisms could have been lofted from the surface of the Earth.
This discovery is so profoundly important for science that it needs to be repeated; but the desire to repeat it is difficult to find. A similar experiment, however, is being planned by a team of scientists led by Professor Dhammika Maganarachchi at the National Institute of Fundamental Studies and myself. A balloon launch to this end is being planned within the next six months. The team at NIFS will be assisted by my grandson, Reuben Chandra Wickramasinghe, who has a visiting appointment at the Mathematics Department of the University of Colombo.
Concluding remarks
I believe that in 2023 we have reached a crucial turning point in the history of human civilization. When it is finally accepted that life on Earth is a minuscule part of a vast cosmic biosphere the implications for humanity will be profound. Even more important would be the recognition that alien life in the form of microbes – bacteria and viruses – exist in our very midst even now and are continually raining down on our planet. Such microbes could be responsible for devastating pandemics, but more positively, we should recognise cosmic viruses and bacteria could have the potential to augment our genomes – the genomes of all terrestrial lifeforms – and over long periods unravel an ever-changing panorama of cosmic life.
Whilst advances in technology continue at accelerating pace humanity as a whole is becoming ever more fractured. Wars and bitter sectarian conflicts and heart-rending suffering are to be seen everywhere. The “climate-change” marches and protestations of young people that are gaining momentum are perhaps emblematic of a desire to rebel against reigning paradigms that seem to be threatening our very existence.
Thomas Kuhn famously declared “…when paradigms change, the world changes with them.” One could perhaps assert that a reversal of this causality is also possible – “when the world changes paradigms can be forced to change.”

Universities, as centres of learning, must not be politicised
“They must foster the abiding values of freedom of thought and expression, respect and tolerance for viewpoint difference …”
Address recently delivered by Professor Savitri Goonesekere,
former Vice-Chancellor and emeritus Professor of Law of the university of Colombo,
at the establishment of the Prof. G.L. Peiris Trust for Legal Education and Research.
Thank you, Professor Peiris, for inviting me to speak this evening at an event to announce the endowment that is being made to the University of Colombo and the Sri Lanka Law College as the G. L. Peiris Trust for Legal Education and Research.
You and I have walked the corridors of this beautiful building as Vice Chancellors of this university. The walls of the Senate Room carry our portraits, but do not reflect the experiences that we have had in that capacity. We worked in this institution and chaired Senates and Councils. These fora were places that gave us an opportunity to respect viewpoint differences that were shared in an environment of collegiate connectivity, often in challenging times, when violence in armed conflict was a lived experience for all Sri Lankans.
This is also an occasion to share with this audience a day in this building when you had to confront the horror of the assassination of your predecessor, Professor Stanley Wijesundere, just across from your office. This was summary justice by the then JVP for taking decisions in academic bodies of the university in medical education. I was at the time Dean of the Faculty of Humanities and Social Sciences at the Open University in Nawala. Yet we connected across Universities, supported each other to cope with those dark times. You, as Vice-Chancellor of this University, and my Vice-Chancellor, the late Professor Dayantha Wijesekere, collaborated to network and respond to violence against staff and students from non-state and state actors. University Teachers for Human Rights was born at this time with the support of both Vice-Chancellors.
Some years later, as I walked up the stairs of College House, on what I expected to be a routine day, a colleague ran down that staircase to say that a former student and cherished friend, Dr. Neelan Tiruchelvam, had just been assassinated. Devastated as I felt, I had no inhibitions in speaking later at his funeral, in what had been a political assassination. I did not have to ask for permission from the University Council to do so.
Today, freedom of thought and speech in academic institutions is being challenged in the United States and our own country in restrictive norms on governance of public institutions. These events of the past and that history are an eloquent reminder that Universities, as centres of learning, must not be politicised. Rather, they must foster the abiding values of freedom of thought and expression, respect and tolerance for viewpoint difference, and bring that voice to both University fora and the public domain. In those times, professors and law teachers did not have to explain to Vice-Chancellors and Deans why they expressed views within and outside Universities on issues of public concern.
Today is a day to also recall Professor Peiris’s own scholarship in the area of public law and particularly on freedom of speech and expression that preceded the dramatically different career path he chose to take. That scholarship will now be available to generations of law students, teachers and lawyers, as well as others, hopefully inspiring an understanding and reflection on fundamental legal principles and concepts that can contribute to the wellbeing and sustainable development of a nation.
The literature and your scholarship that will be shared through the G.L. Peiris Trust will also hopefully be a reminder that “one must know the law as it is, to comment on what it should be”. For your early scholarship is very much in the tradition of analytical positivism that you and I were immersed in as students of the one and only Law Department in Peradeniya and later in this university. We pulled what are called “all-nighters”, as students and teachers, reading in our rooms or in that wonderful library in Peradeniya, referring cases, statutes, Grotius and Voet, the jurists of Civil Law, and of course the great Common Law and Civil Law scholars like Ivor Jennings, H. L. A. Hart, and R.W. Lee.
Professor Peiris, as you all know, came into the University with a stellar record from that institution near the Indian Ocean, where, (as loyal Royalists would have it), scholar students were not the norm. Coming into a University with a scholar’s record does not necessarily translate to a stellar University career. Professor Peiris, with his prodigious capacity for academic work, clarity of thought and writing, thrived in that new learning and teaching environment. He made history in the Law Department, winning every scholarship awarded and graduating at that time with the much prized first-class honours degree. I myself was a young law teacher at the time, and recall that it was impossible to grade GL’s papers with any grade but an A. The length of those contributions, of course, required exhausting attention, and I think taught his teachers to learn how to read carefully. My young grandchildren cannot read a long email from me today without missing a lot of its content!
The G. L. Peiris Trust will provide readers with a rich range of literature on a phenomenal diversity of laws in this country, with comparative jurisprudence from Civil and Common Law countries. If the Rule of Law in a democracy is to be maintained and strengthened, we must reflect on the fact that analytical positivist scholarship is not irrelevant in our times. It is that University tradition that was nurtured in the early post-independence and post-colonial era in Sri Lanka and Civil and Common Law countries that created the foundation for the great later jurisprudence in our own courts and in India. This is especially evident in important areas of public law, including constitutional law and human rights. Justices like A. R. B. Amerasinghe and Mark Fernando and lawyers like Mr. H.L.de Silva and my late husband, R. K. W. Goonesekere, were all alumni connected to this University. Their contribution to jurisprudence and legal reform in this country was nurtured in halls of learning that recognised that we must learn the law as it is, to understand what it ought to be. Professor Peiris himself demonstrates that heritage in his later work on public law and in contributing with another distinguished alumnus, the late Neelan Tiruchelvam, to the draft Constitution of 2000. I hope that the G. L. Peiris Trust will also include papers relating to that work, the best draft Constitution to date, abandoned in what has now become the norm of adversarial politics.
The long overdue institutional connection between university academia and the Law College that is made through the G .L. Peiris Trust is welcome. The Principal of the Law College, Prasantha Lal de Alwis, PC, an alumnus of our Law Faculty, has given leadership in creating a new path that must benefit both institutions.
In my time, students and teachers did not connect outside the halls of learning in later life as Sirs/Madams in perpetuity. They became and interacted as colleagues. As a former teacher, colleague, and Vice-Chancellor of this University, thank you, GL, for this generous endowment. May it be a valued institutional legacy that will inspire commitment to, and understanding of, the Rule of Law in a country that will always be a Democracy.

The silent hunters: Why Sri Lanka’s spiders matter
By Ifham Nizam
They are everywhere, yet most of us hardly notice them. In the corner of a garden, beneath a leaf, across a paddy field, inside a forest or quietly occupying an old tree, spiders are constantly at work.
They may be tiny enough to escape the human eye or large enough to command attention, but beneath their often-misunderstood appearance lies an ecological workforce that performs one of nature’s most important jobs.
They hunt
And in doing so, spiders help keep insect populations under control, strengthen food webs and contribute to the delicate ecological balance upon which both natural ecosystems and agriculture depend.
For Sri Lanka, a country celebrated for its extraordinary biodiversity and high degree of endemism, the world of spiders is particularly fascinating. Yet it remains one of the lesser-known chapters of the island’s natural history.
Field biologist and researcher Dr. Ranil Nanayakkara has spent years helping to open that chapter.
His work on Sri Lanka’s spiders, including the spectacular tiger spiders of the genus Poecilotheria, has demonstrated that there is much more to these creatures than the fear and suspicion with which they are often regarded.
Nanayakkara has been involved in the description and documentation of several remarkable Sri Lankan tarantulas, including Poecilotheria rajaei and Poecilotheria srilankensis, as well as Chilobrachys jonitriantisvansickleae. His research has also taken him into the less-studied corners of Sri Lanka’s biodiversity.
His approach is significant because the story of Sri Lanka’s spiders is not simply a story about unusual or frightening creatures. It is a story about ecosystems.
Nature’s pest controllers
A spider sitting motionless in a web may appear inactive, but its ecological role can be anything but passive.
Spiders are predators, feeding predominantly on insects and other arthropods. Across an agricultural landscape, this makes them natural allies of farmers.
Moths, beetles, flies, grasshoppers, leafhoppers, planthoppers and many other insects become part of the prey base of different spider species.
Some spiders wait patiently in intricately constructed webs. Others actively hunt across leaves, vegetation and the soil surface. Jumping spiders stalk their prey with remarkable precision, while wolf spiders move across the ground rather than depending on webs to capture food.
Different species therefore occupy different ecological niches.
Together, they form an army of natural predators.
This is why the presence of spiders in a paddy field or vegetable plot should not automatically be interpreted as something undesirable. On the contrary, their presence may be an indication that a functioning predator community is at work.
Nanayakkara’s own publication, An Introduction to Common Spiders of Sri Lanka, was designed partly to introduce the public and research community to these frequently overlooked animals.
The book covers spider morphology, natural history and Sri Lankan spider families, while highlighting their importance as biological control agents and bioindicators.
- Genus -Sason
- Chilobrachy jonitriantisvansickelei
The invisible service
There is an important ecological service taking place every day that does not appear on an agricultural balance sheet.
A spider catches an insect.
Then another.
And another.
Multiply that interaction by thousands of spiders across thousands of hectares and the ecological significance becomes enormous.
Unlike a pesticide, a spider does not need to be manufactured, transported, mixed or sprayed. It does not require a farmer to purchase another container or return to the field with a spray machine.
It simply performs its ecological role.
That does not mean spiders can replace all forms of pest management. Rather, they can form one component of integrated pest management, in which natural predators, parasites, cultural practices and carefully targeted interventions work together.
The objective should not necessarily be to create an agricultural landscape in which every insect disappears.
It should be to create one in which pest populations are kept below damaging levels through a functioning ecological system.
When pesticides kill the allies
This is where the story takes a darker turn.
Broad-spectrum insecticides are designed to kill insects, but the ecological world does not always recognise the distinction between a farmer’s target species and a beneficial predator.
When chemicals are applied indiscriminately, spiders and other predatory arthropods can also be affected.
The consequences can be surprisingly complex.
A pesticide application may reduce a crop pest rapidly. But if it simultaneously reduces the predators that feed on that pest, the field may lose part of its natural defence system.
As surviving pest populations recover, farmers may again reach for the sprayer.
The result can become a vicious circle: fewer natural predators, greater reliance on chemicals and repeated disruption of the ecological relationships that once helped regulate pest populations.
Pesticides can also move beyond the field through runoff, spray drift and other pathways, potentially affecting surrounding vegetation, wetlands and waterways.
The real cost of chemical-intensive agriculture, therefore, cannot always be measured simply by the price of a bottle of pesticide.
There can be an ecological cost that remains invisible.
A paddy field is more than a crop
Sri Lanka’s paddy fields are often viewed through the lens of production: acreage, yield, irrigation, fertiliser and harvest.
But look more closely and another world emerges.
Between the rice plants are insects. In the water are aquatic organisms. Along the bunds are grasses and other vegetation. Amphibians move through the landscape. Birds forage. Reptiles pass through.
Microorganisms work beneath the surface.
And somewhere among the vegetation, spiders wait.
The paddy field is therefore not simply a food-production unit. It is an ecosystem.
Field margins, bunds, grasses and neighbouring vegetation can provide shelter and alternative habitat for spiders and other beneficial organisms. Maintaining this ecological complexity can help predator populations persist and recolonise cultivated areas.
Destroying those refuges or exposing them repeatedly to chemicals can simplify the ecosystem and weaken its natural resilience.
The spectacular world of tiger spiders
If ordinary garden spiders are largely invisible to the public, Sri Lanka’s tarantulas are impossible to ignore.
The genus Poecilotheria, commonly known as tiger spiders or ornamental tarantulas, includes some of the island’s most spectacular arachnids.
Their intricate patterns, extraordinary size and specialised lifestyles have made them subjects of scientific fascination.
Nanayakkara’s work brought international attention to this hidden world.
One of the best-known examples is Poecilotheria rajaei, a tarantula described from northern Sri Lanka after specimens were encountered during field surveys. The species was formally described in 2012 by Ranil Nanayakkara and co-authors.
The story illustrates something important about biodiversity research: discovery does not necessarily begin in a sophisticated laboratory.
Sometimes it begins in a forest.
Sometimes it begins with a local observation.
And sometimes it begins when a field researcher is willing to look closely at something that most people would rather avoid.
Another remarkable chapter came with Poecilotheria srilankensis, described from Belihuloya in 2019. The research documented another arboreal tarantula from Sri Lanka and added to understanding of the island’s highly distinctive Poecilotheria fauna.
Nanayakkara and his collaborators have also documented Chilobrachys jonitriantisvansickleae, a tarantula associated with a fragmented forest patch in Sri Lanka’s wet zone.
These discoveries are not merely additions to a scientific list.
Each species raises questions.
Where does it live?
What does it eat?
How large is its population?
What habitat does it require?
How isolated are its populations?
What happens when its forest disappears?
The blue surprise in the forest
Perhaps nothing illustrates the richness of this hidden world better than the discovery of a striking blue tarantula in Sri Lanka’s rainforests.
The species, Chilobrachys jonitriantisvansickleae, was found in an isolated patch of southwestern rainforest surrounded by tea and rubber plantations. Its vivid blue colouring helped attract attention to an animal living in a highly fragmented landscape.
It is an important reminder that biodiversity does not always survive in vast wildernesses.
Sometimes it survives in small fragments.
And when a species is closely associated with a particular habitat, the destruction of even a relatively small area can have disproportionate consequences.
Beyond fear
One of Nanayakkara’s important contributions has been to make spiders accessible to people who may otherwise never look beyond their reputation.
His books, including An Introduction to Common Spiders of Sri Lanka and Poecilotheria – “Tiger Spiders” of Sri Lanka, have helped bring information about these animals to a wider audience. His Tiger Spiders of Sri Lanka focuses on the identification, habitats, behaviour and conservation of Poecilotheria.
The challenge is not simply scientific.
It is cultural.
For generations, spiders have often been associated with fear, danger and something that should immediately be killed.
But understanding changes attitudes.
Once a spider is seen as a predator rather than a pest, its role begins to look different.
Once a tarantula is understood as a specialised inhabitant of a particular forest habitat, destroying that habitat becomes a conservation issue rather than merely a matter of removing an unpleasant creature.
Small predators, enormous consequences
Spiders are also prey.
Birds, amphibians, reptiles and other animals depend on arthropods as part of their diets. Spiders consequently occupy several positions in food webs: they are predators of insects and, in turn, food for other animals.
Their disappearance can therefore create effects that travel through an ecosystem.
This is why biodiversity conservation cannot focus exclusively on elephants, leopards, birds or other charismatic wildlife.
The ecological machinery of a forest is also made up of creatures that are small, obscure and rarely photographed.
Some may never make the headlines.
But remove enough of them and the system changes.
A call to look closer
Sri Lanka still has much to learn about its spiders.
Taxonomy remains fundamental. Before conservationists can determine how a species is faring, they need to know what species exist, where they occur and how they differ from one another.
Field research is equally important because many species cannot be understood simply by examining specimens in collections.
Their habitats, behaviour, prey, reproduction and relationships with other organisms all matter.
Nanayakkara’s research illustrates the value of this patient field-based approach. His work has contributed to the documentation of Sri Lanka’s lesser-known biodiversity and to the scientific understanding of spiders that had previously received little attention.
But perhaps the larger lesson is even simpler.
Nature does not waste species.
The spider spinning a web beside a paddy field, the hunter moving through the undergrowth and the spectacular tarantula hidden in a forest tree are all pieces of a much larger ecological puzzle.
Protect the predators
Conserving spiders does not mean protecting every individual spider from every natural threat.
It means protecting the ecosystems that allow spider populations to survive.
It means reducing unnecessary pesticide use.
It means encouraging integrated pest management.
It means maintaining vegetation around agricultural fields, protecting forest fragments and conserving wetlands and streams.
It means giving farmers the knowledge to recognise that some of the creatures living among their crops are not enemies at all.
They are allies.
For Sri Lanka, there is another urgent reason to look more closely.
The island’s biodiversity is exceptional, but its habitats are increasingly fragmented and altered. The loss of specialised habitat can be particularly serious for species with narrow ecological requirements.
The work of researchers such as Dr. Ranil Nanayakkara reminds us that discovery and conservation are inseparable.
We cannot protect what we do not know.
And we cannot appreciate what we have never learned to see.
The next time a spider appears in a garden, on a paddy bund or quietly beneath a leaf, perhaps it deserves something more than a broom or a spray can.
It may be doing what nature designed it to do—hunting, regulating and maintaining balance.
For millions of years, spiders have been doing this work without asking for recognition.
Perhaps it is time we gave them some.
When we protect the predators, we protect the balance.

West Asian conflict undergoing manifold complications
Israeli Prime Minister Benjamin Netanyahu’s message to Israel’s enemies was blunt and stark.‘We’re going to win; we have no choice.’ He said so while the majority of attendees at a recent UN General Assembly session walked out of the conference hall when the Israeli Prime Minister took the podium; many of them booing in derision.
Those commentators who have been studying Israel’s handling of her enemy states over the decades are unlikely to dismiss the entirety of Netanyahu’s address as rhetoric. The general pattern has been for the Israeli state to stand up firmly against its enemies in the battle field. On most occasions, these adversaries have been beaten back.
It is also little realized in particularly the Southern hemisphere that Israel, for the most part, could defend herself without much US assistance. The history of the conflict bears this out.
However, from the viewpoint of working towards a just and equitable peace in the Middle East the Israeli hard line stance has proved and will prove incalculably detrimental. The sworn enemies of Israel are not going to be in any way deterred by Netanyahu’s stark warnings. On the other hand, they would be only further provoked into taking on Israel by conventional or unconventional military means and seek its destruction.
The recent aborted mid-air hijacking of a Flydubai flight, consisting mainly of Israeli passengers, by an Omani extremist drives home the point. Israel’s enemies are bound to redouble their efforts to annihilate Israel rather than be deterred by the latter’s warnings about standing firm against them. This too history has proved.
It would be in the fitness of things at this juncture to pay a tribute to the professionalism, courage and humanity of the relevant airline pilot, Captain Machchhar, whose timely action proved decisive in botching the hijack attempt. His intervention averted what could very well have been another 9/11 type tragedy. History is not going to forget his daring and resourcefulness.
Meanwhile, the ground realities in West Asia are undergoing further complications that portend increasing regional instability. For example at the time of writing Turkiye, Pakistan and Saudi Arabia have agreed under the recently established ‘Mecca Alliance for Defence’ to deploy ‘deterrence measures’ collectively in the event of any member of the alliance coming under military strikes from a non-member state.
The agreement is modeled on the NATO collective defence pact and should help in defusing any threat perceptions experienced by the alliance members in the short term. However, the group would need to be cognizant of the major and potentially divisive role Iran could play in the interstate politics of the Middle East region going forward.
Iran’s reported support, for example, for Yemen’s Houthi rebels, who are engaged in attacking Saudi national assets, could at some point in time compel the alliance, under the terms of the pact, to initiate deterrent military measures against Iran.
The implications for regional peace from such a turn of events hardly require elaboration. A full blown regional war emerges as a distinct possibility if Iran sees itself as being excessively antagonized by the alliance. A further complication is that antagonistic sectarian identities of an Islamic kind could come to play hugely divisive roles in it. Shiite Islamic states would be inclined to back Iran while those countries seen as Sunni Islamic in orientation are bound to support Saudi Arabia.
Accordingly, West Asia is a region rife with manifold aggravated insecurities. If the latter are not defused dexterously they could escalate into a conflict of extra regional dimensions. The latter development would render the world a collective loser.
Unfortunately, no constructive help could be expected from the US at this juncture by way of working towards regional and international peace even of short durance. Its war against Iran has only aggravated the world’s current insecurities.
For example, the world has been compelled to face the possibility of compounded economic woes as a consequence of the Hormuz crisis remaining unresolved. The world is currently experiencing what could be seen as a ‘winter of economic discontent’ of unprecedented proportions.
Unfortunately, the international community is to all intents and purposes helpless in the face of this multifaceted crisis. Substantial intervention is expected of the UN but since it has failed to reform itself over the years it is compelled to stand idly by while the world’s insecurities heighten and multiply.
Yet, it is the seemingly paralyzed UN system that has some potential to contain the current tide of international disorder to even a small measure. Given the persisting divergent and conflicting interests among the world’s principal power blocs, the G7 and BRICS for instance, it is mainly the UN and its principal agencies that could carry some credibility as peace brokers and mediators.
However, as an initial step towards bringing the principal protagonists to the negotiating table the UN would need to convince the principal powers of the UN Security Council of the need for a substantive broad-basing of the membership of the Council so as to reflect more accurately the current global political and economic realities. Such reforms would render the Council more representative and help in strengthening its credibility and effectiveness.
The above reforms call for years of dynamism, hard work and resourcefulness on the part of the international community, read the UN. Yet the aims are not impossible to achieve if strong leadership is brought to bear by the UN.
Meanwhile, the UN agencies and allied organizations need to pay stepped-up attention to the West Asian theatre and its wasting conflicts and wars. Here too there is immense hard work to be put in.
There is, for instance, identity politics and its issues that need to be managed urgently. While internal political matters of countries could not be addressed directly by UN agencies, awareness-raising programs and projects could be energetically carried out by them to blunt the appeal of identity-based slogans, relating to, for instance, religion and race.
Besides, values at the heart of democratic politics need to be freshly and enthusiastically propagated. Vast reserves of energy and resources are needed, to be sure, to consistently champion and implement these crucial projects but they need to be pursued single-mindedly if even a dent is to be made in the current runaway global disorder.
The aborted hijacking of the Flydubai flight pointed to the dehumanizing impact of identity politics on the human consciousness. It was also an indication that those sections endowed with humanity cannot stand idly by while identity politics continues to destroy civilizational values. The time to act is ‘now’.
