Tragic ignorance underlying the maligning of “Born Again Christianity”

Published

A clarification in the context of Easter 2023

By Professor A. N. I. Ekanayaka
Emeritus Professor

Amidst much of the irrationality and ignorance that bedevils Sri Lankan society nowadays, the tendency to disparage what is called “born again Christianity” is one of the more prominent examples. The approach of Easter 2023 is an opportune time in which to dispel the ignorance and prejudice underlying this attitude. Across much of society from those in high places to the ordinary man in the street, from prominent politicians to many so-called learned intellectuals, and dominantly amongst some Buddhist clergy and their adherents, there is the notion that while it is perfectly respectable to belong to a mainline Christian denomination, “born again Christianity” is some weird fundamentalist cult that needs to be resisted. Little do they realise that in doing so they are opposing Christianity itself where the need to be “born again” (i. e. spiritually regenerate), is a sine qua non that lies at the very heart of authentic biblical Christian doctrine, as was strongly emphasised by Jesus himself in his earthly ministry.

Opposition to Christianity however is not the issue. Such opposition is as old as the Christian faith. The blood of the martyrs down the running centuries is testimony to that fact. Even in today’s world research shows that Christianity is by far the most persecuted of all religions. That is not surprising. The Christian diagnosis of the human predicament and its prescription of the biblical Gospel as the one and only path of salvation open to mankind is so unique and radical as to invariably evoke the ridicule and hostility of the world. That is the testimony of history through all generations.

Accordingly, that people should be derisive of born again Christianity is to be expected. But let them not delude themselves into thinking that in so doing they are not also opposing Christianity. The truth is that by doing so they are attacking the very foundations of historic bible-based Christianity. True Christianity according to the bible is in and of itself nothing less than ‘born again Christianity”! Christianity is nothing if not “born again Christianity”. Whether people like it or not that is the plain truth. This article is intended to clarify this reality

Ironically, the tendency to disparage “born again Christianity” is not confined to those who are outside the Christian Church. Sadly, many so-called Christians themselves know little or nothing of this fundamental doctrine. Consequently, they live out their entire life as regular church goers comforting themselves with formal religion and empty ritual, and finally go to the grave in darkness without having ever understood the immeasurable riches of the biblical Gospel and what it means to be a born again regenerate Christian enjoying the guarantee of eternal security who can say with the great apostle Paul “for me to live is Christ and to die is gain” !

Many apostate prelates in the mainline churches must bear heavy responsibility for the ignorance of ordinary Christians about the Christian gospel in which being born again (i.e. becoming spiritually regenerate not through human endeavour but through the decisive intervention of God in transforming the human heart), is an essential part. Those to blame for such widespread ignorance include many bishops priests and even popes and cardinals who steeped in the heresies of a spurious liberal theology, wallowing in religious pluralism and denying the absolute authority of scripture, fail to convey to their congregations the whole truth about their faith and what it means to be a Christian. Instead, they promote an unbiblical fallacious lukewarm sentimental Christianity after their own imagination with notions and practices that neither challenge the wisdom of the secular world nor conflict with the teachings of other religions.

No wonder so many unregenerate Christians who have themselves never experienced the miracle of being ‘born again’ feel no sense of outrage when something as basic as born again Christianity is subject to widespread scorn and ridicule in secular society and by those of other faiths. Nor do many apostate bishops and priests feel bad about it either, having neglected to lead their own people within the Church into the experience of being regenerate (born again) Christians. Given their theological devience, ignorance of scripture, doctrinal confusion, and being timid religious pluralists unwilling to say anything that might conflict with the teachings of other religions, it is not surprising that such clergy should maintain a stoic embarrassed silence when born again Christianity is disparaged by those outside the Church.

At the other end of the spectrum are some pastors and evangelists of smaller denominations who though they are not ashamed to proclaim the necessity for Christians to be “born again” do so in a shallow manner that trivialises, cheapens, dilutes and distorts the doctrine of spiritual regeneration in the truly born again Christian as taught by Jesus. Those who are guilty of this include certain charismatic groups and their populist preachers with a shallow and superficial understanding of salvation through the biblical Gospel. Worse the slogan of born again Christianity could be maliciously exploited by opulent politically influential charismatic heretics who lead satanic cults and posing as ‘prophets’ in complete defiance of scripture deceive thousands in gargantuan mega churches where they preach a pernicious ‘prosperity theology’ that is as evil and heretical as the ‘liberal theology’ which makes bishops and priests of the mainline Churches underplay the importance of ‘born again Christianity’.

On the other hand, for people of other faiths especially Buddhists and Hindus to disparage “born again Christianity” is also unfair and inconsistent. The fact is nearly all religions have some concept of rebirth deeply ingrained in their philosophy (however different it may be to the Christian understanding of spiritual regeneration). For example, to deny rebirth would be a violation of one of the most basic tenets of Buddhism.

The Buddha himself accepted the premises and concepts relating to rebirth and there are several references to rebirth in early Buddhist texts including several Suttas. What is rebirth unless it is one particular understanding of being born again? Consequently, it is particularly unkind and illogical that any Buddhist should look down on ‘Born again Christians’. In Hinduism, too, the Bhagavad Gita acknowledges that every human being has a choice to get out of the cycle of rebirth. So, where Hinduism, Jainism, Buddhism, and Sikhism all in their own way have a doctrine of new birth which goes to the very foundation of these religions, it is perplexing why the peculiarly Christian understanding of regeneration should evoke so much cynicism.

It only in Christianity that being born again is understood hopefully and expectantly as a glorious consummation devoutly to be desired, the gateway to peace joy and victorious living in this life whatever its sufferings, and the passport to the glories of eternal life to come in the heavenly kingdom where the scriptures promise that God will dwell with his people “and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain anymore, for the former things have passed away” (Rev.21: 3-4)

The glorious optimism of the Christian understanding of being spiritually ‘born again’ here and now and the cast iron guarantee of eternal security that it includes contrasts with the depressing pessimism that surrounds all other conceptions of rebirth/or being ‘born again’ in other religions. So, the cynicism towards ‘born again Christianity’ may in part be the reaction of those whose own conception of new birth according to their belief system amounts to a depressing intangible mystical notion of reincarnation which dependent on the vagaries of human endeavor and being rooted in abstract philosophy is hard to understand and offers little to look forward to. This may also explain the conversion anxiety which drives the continuing hostility towards evangelists who peacefully preach the doctrine of ‘born again Christianity’ in the community.

In the free market of human ideology especially pertaining to matters of life and death, notions of salvation that are grounded in incontrovertible historical events, stand the test of time in the furnace of human experience, are of greater immediate value in coping with the problems of life, and are seen to guarantee the consolation of eternal security beyond death, will inevitably be more attractive. The great hope and eternal truth of the Christian Gospel that lies at the heart of ‘born again Christianity’ has this advantage. Consequently, it is not surprising that those who are alarmed at the prospect of peaceful conversions to the Christian religion should seek to stigmatize the notion of being a born again Christian.

So, what is this doctrine of being ‘born again’ that lies at very heart of the Christian religion ? The concept in one way or another underlies the entire Bible from start to finish where all scripture is the Word of God spoken and the record of God’s historic offensive against human sin in a fallen universe where all human beings in their natural state in every generation find themselves alienated from God, in a state of total depravity and total inability to save themselves by their own meritorious works. In this context, the specific reference to the imperative of being “born again” goes back to a memorable encounter in the life of Jesus, who controversially claimed to be God himself incarnate as the perfect human being, who had come into the world to save sinners. He would achieve this by being their sin bearer and redeemer thereby atoning for their sins through his bitter suffering and death on the cross, before his mighty resurrection three days later as predicted.

One night a distinguished ruler of the Jews and a member of the Jewish Sanhedrin named Nicodemus visited Jesus secretly for fear of being found out by his peers. Nicodemus was curious to know more about Jesus’ identity and the core of his teaching. The scriptures record that to Nicodemus’s astonishment Jesus cut through unessentials and went straight to the point saying “Truly, truly I say to you, unless one is born again he cannot (even) see the kingdom of God” ! (Jn 3:3). Unable to make sense of the spiritual metaphor used by Jesus Nicodemus reportedly lapsed into good humoured cynicism exclaiming that such a suggestion was as preposterous as a man “entering a second time into his mother’s womb and being born”. But Jesus was adamant insisting that unless one is born again “he cannot enter the kingdom of God” (Jn 3:5). “You must be born again” (Jn 3:7) he reiterated. It is one of the most explicit warnings Jesus ever issued during his earthly ministry. Let there be no mistake. It is this warning that people belittle nowadays when they make light of born again Christianity.

One of the greatest theologians of the age Dr JI Packer has explained that being “born again” was a picture phrase Jesus used in his conversation with Nicodemus to depict the concept of “Regeneration”. It is “God renovating the heart, the core of a person’s being, by implanting a new principle of desire, purpose and action, a dispositional dynamic that finds expression in a positive response to the (biblical) Gospel and its Christ” : i. e. saving faith. From first to last such regeneration is seen entirely as the work of God, where God raises those whom he has chosen among the spiritually dead to new life in Christ Jesus as Christians. Dr David Martyn Lloyd Jones the brilliant physician who gave up medicine to become the greatest preacher in England last century, in his book “Experiencing the New Birth” explained that Christianity is that which brings a person to a personal knowledge of God. True (born again) Christianity is knowing God he said. “Not just believing a few things about God and having a nice little life. That is not Christianity. That is nothing but morality or mere religion”. The essence of the new birth is beginning to know and have communion with God, a radical conversion that will be publicly reflected in a transformed lifestyle which in every detail of daily life acknowledges the Lordship of Christ.

That in brief is what “born again” means in Christianity. That is the glorious God driven consummation that people disparage when they in their ignorance mock born again Christianity. Hopefully, those who stand corrected by this clarification will cease doing so rather than further imperil their own souls by stigmatising the truth.

Finally, those who presume to write about such matters if they are to be credible witnesses to the truth must themselves be able to lay some claim in all humility to a personal experience of what it means to be born again from a uniquely Christian perspective. True, this may lay them open to a charge of committing intellectual suicide or worse arrogant self-righteous, holier than thou presumption where on the surface they appear to be flawed personalities no better than other people.

But such cynical reactions are themselves an example of the ignorance surrounding born again Christianity. Jesus once said, “Those who are well have no need of a physician but those who are sick. For I came not to call the righteous but sinners” (Matt 9:12-13). In the Christian understanding salvation through being born again represents the spiritual liberation of those, even the dregs of society, who lamenting their sins and acknowledging their wretchedness, bemoaning their total depravity and inability to save themselves and putting their faith in Christ, find themselves unworthy recipients of the free gift of God through grace. The great apostle Paul, who himself admitted to being the “very least of all the saints …” (Eph 3:8), writing from a Roman prison about AD 60 put it perfectly: “For by grace you have been saved through faith. And this is not your own doing. It is the gift of God. Not a result of (meritorious) works so that no one may boast” (Eph 2:8-9). So it was with the regenerate John Newton formerly the degenerate wretched captain of a slave ship and an investor in the slave trade (later becoming an evangelical English cleric and slavery abolitionist), who in 1772 wrote this memorable lyric :

Amazing grace how sweet the sound
That saved a wretch like me,
I once was lost, but now I’m found,
Was blind but now I see
That is what it means to become a “born again Christian”.

Retirement age for judges: Innovation and policy

Published

on

I. The Constitutional Context

Independence of the judiciary is, without question, an essential element of a functioning democracy. In recognition of this, ample provision is made in the highest law of our country, the Constitution, to engender an environment in which the courts are able to fulfil their public responsibility with total acceptance.

As part of this protective apparatus, judges of the Supreme Court and the Court of Appeal are assured of security of tenure by the provision that “they shall not be removed except by an order of the President made after an address of Parliament supported by a majority of the total number of members of Parliament, (including those not present), has been presented to the President for such removal on the ground of proved misbehaviour or incapacity”[Article 107(2)]. Since this assurance holds good for the entirety of tenure, it follows that the age of retirement should be defined with certainty. This is done by the Constitution itself by the provision that “the age of retirement of judges of the Supreme Court shall be 65 years and of judges of the Court of Appeal shall be 63 years”[Article 107(5)].

II. A Proposal for Reform

This provision has been in force ever since the commencement of the Constitution. Significant public interest, therefore, has been aroused by the lead story in a newspaper, Anidda of 13 March, that the government is proposing to extend the term of office of judges of the Supreme Court and the Court of Appeal by a period of two years.

This proposal, if indeed it reflects the thinking of the government, is deeply disturbing from the standpoint of policy, and gives rise to grave consequences. The courts operating at the apex of the judicial structure are called upon to do justice between citizens and also between the state and members of the public. It is an indispensable principle governing the administration of justice that not the slightest shadow of doubt should arise in the public mind regarding the absolute objectivity and impartiality with which the courts approach this task.

What is proposed, if the newspaper report is authentic, is to confer on judges of two particular courts, the Supreme Court and the Court of Appeal, a substantial benefit or advantage in the form of extension of their years of service. The question is whether the implications of this initiative are healthy for the administration of justice.

III. Governing Considerations of Policy

What is at stake is a principle intuitively identified as a pillar of justice.

Reflecting firm convictions, the legal antecedents reiterate the established position with remarkable emphasis. The classical exposition of the seminal standard is, of course, the pronouncement by Lord Hewart: “It is not merely of some importance, but is of fundamental importance that justice should not only be done, but should manifestly and undoubtedly be seen to be done”. (Rex v. Sussex Justices, ex parte McCarthy). The underlying principle is that perception is no less important than reality. The mere appearance of partiality has been held to vitiate proceedings: Dissanayake v. Kaleel. In particular, reasonableness of apprehension in the mind of the parties to litigation is critical: Ranjit Thakur v. Union of India, a reasonable likelihood of bias being necessarily fatal (Manak Lal v. Prem Chaud Singhvi).

The overriding factor is unshaken public confidence in the judiciary: State of West Bengal v. Shivananda Pathak. The decision must be “demonstrably” (Saleem Marsoof J.) fair. The Bar Association of Sri Lanka has rightly declared: “The authority of the judiciary ultimately depends on the trust reposed in it by the people, which is sustained only when justice is administered in a visibly fair manner”.

Credibility is paramount in this regard. “Justice has to be seen to be believed” (J.B. Morton). Legality of the outcome is not decisive; process is of equal consequence. Judicial decisions, then, must withstand public scrutiny, not merely legal technicality: Mark Fernando J. in the Jana Ghosha case. Conceived as continuing vitality of natural justice principles, these are integral to justice itself: Samarawickrema J. in Fernando v. Attorney General. Institutional integrity depends on eliminating even the appearance of partiality (Mandal Vikas Nigam Ltd. v. Girja Shankar Pant), and “open justice is the cornerstone of our judicial system”: (Sahara India Real Estate Corporation Ltd. v. SEBI).

IV. Practical Constraints

Apart from these compelling considerations of policy, there are practical aspects which call for serious consideration. The effect of the proposal is that, among all judges operating at different levels in the judicature of Sri Lanka, judges of the Supreme Court and the Court of Appeal only, to the exclusion of all other judges, are singled out as the beneficiaries of the proposal. An inevitable result is that High Court and District Judges and Magistrates will find their avenues of promotion seriously impeded by the unexpected lengthening of the periods of service of currently serving judges in the two apex courts. Consequently, they will be required to retire at a point of time appreciably earlier than they had anticipated to relinquish judicial office because the prospect of promotion to higher courts, entailing higher age limits for retirement, is precipitately withdrawn. Some degree of demotivation, arising from denial of legitimate expectation, is therefore to be expected.

A possible response to this obvious problem is a decision to make the two-year extension applicable to all judicial officers, rather than confining it to judges of the two highest courts. This would solve the problem of disillusionment at lower levels of the judiciary, but other issues, clearly serious in their impact, will naturally arise.

Public service structures, to be equitable and effective, must be founded on principles of non-discrimination in respect of service conditions and related matters. Arbitrary or invidious treatment is destructive of this purpose. In determining the age of retirement of judges of the Supreme Court and the Court of Appeal, some attention has been properly paid to balance and consistency. The age of retirement of a Supreme Court judge is on par with that applicable to university professors and academic staff in the higher education system. They all retire at 65 years. Members of the public service, generally, retire at 60. Medical specialists retire at 63, with the possibility of extension in special circumstances to 65. The age of retirement for High Court Judges is 61, and for Magistrates and District Judges 60. It may be noted that the policy change in 2022 aimed at specifically addressing the issue of uniformity and compatibility.

If, then, an attempt is made to carve out an ad hoc principle strictly limited to judicial officers, not admitting of a self-evident rationale, the question would inevitably arise whether this is fair by other categories of the public service and whether the latter would not entertain a justifiable sense of grievance.

This is not merely a moral or ethical issue relating to motivation and fulfillment within the public service, but it could potentially give rise to critical legal issues. It is certainly arguable that the proposed course of action represents an infringement of the postulate of equality of treatment, and non-discrimination, enshrined in Article 12(1) of the Constitution.

There would, as well, be the awkward situation that this issue, almost certain to be raised, would then have to be adjudicated upon by the Supreme Court, itself the direct and exclusive beneficiary of the impugned measure.

V. Piecemeal Amendment or an Overall Approach?

If innovation on these lines is contemplated, would it not be desirable to take up the issue as part of the new Constitution, which the government has pledged to formulate and enact, rather than as a piecemeal amendment at this moment to the existing Constitution? After all, Chapter XV, dealing with the Judiciary, contains provisions interlinked with other salient features of the Constitution, and an integrated approach would seem preferable.

VI. Conclusion

In sum, then, it is submitted that the proposed change is injurious to the institutional integrity of the judiciary and to the prestige and stature of judges, and that it should not be implemented without full consideration of all the issues involved.

Ranked 134th in Happiness: Rethinking Sri Lanka’s development through happiness, youth wellbeing and resilience

Published

on

In recent years, Sri Lanka has experienced a succession of overlapping challenges that have tested its resilience. Cyclone Ditwah struck Sri Lanka in November last year, significantly disrupting the normal lives of its citizens. The infrastructure damage is much more serious than the tsunami. According to World Bank reports and preliminary estimates, the losses amounted to approximately US$ 4.1 billion, nearly 4 per cent of the country’s Gross Domestic Product. Before taking a break from that, the emerging crisis in the Middle East has once again raised concerns about potential economic repercussions. In particular, those already affected by disasters such as Cyclone Ditwah risk falling “from the frying pan into the fire,” facing multiple hardships simultaneously. Currently, we see fuel prices rising, four-day workweeks, a higher cost of living, increased pressure on household incomes, and a reduction in the overall standard of living for ordinary citizens. It would certainly affect people’s happiness. As human beings, we naturally aspire to live happy and fulfilling lives. At a time when the world is increasingly talking about happiness and wellbeing, the World Happiness Report provides a useful way of looking at how countries are doing. The World Happiness Report discusses global well-being and offers strategies to improve it. The report is produced annually with contributions from the University of Oxford’s Wellbeing Research Centre, Gallup, the UN Sustainable Development Solutions Network, and other stakeholders. There are many variables taken into consideration for the index, including the core measure (Cantril Ladder) and six explanatory variables (GDP per Capita ,Social Support,Healthy Life Expectancy,Freedom to Make Life Choices,Generosity,Perceptions of Corruption), with a final comparison.

According to the recently published World Happiness Report 2026, Sri Lanka ranks 134th out of 147 nations. As per the report, this is the first time that Sri Lanka has suffered such a decline. Sri Lanka currently trails behind most of its South Asian neighbours in the happiness index. The World Happiness Report 2026 attributes Sri Lanka’s low ranking (134th) to a combination of persistent economic struggles, social challenges, and modern pressures on younger generations. The 2026 report specifically noted that excessive social media use is a growing factor contributing to declining life satisfaction among young people globally, including in Sri Lanka. This calls for greater vigilance and careful reflection. These concerns should be examined alongside key observations, particularly in the context of education reforms in Sri Lanka, which must look beyond their immediate scope and engage more meaningfully with the country’s future.

In recent years, a series of events has triggered political upheaval in countries such as Nepal, characterised by widespread protests, government collapse, and the emergence of interim administration. Most reports and news outlets described this as “Gen Z protests.” First, we need to understand what Generation Z is and its key attributes. Born between 1997 and 2012, Generation Z represents the first truly “digital native” generation—raised not just with the internet, but immersed in it. Their lives revolve around digital ecosystems: TikTok sets cultural trends, Instagram fuels discovery, YouTube delivers learning, and WhatsApp sustains peer communities. This constant, feed-driven engagement shapes not only how they consume content but how they think, act, and spend. Tech-savvy and socially aware, Gen Z holds brands to a higher standard. For them, authenticity, transparency, and accountability—especially on environmental and ethical issues—aren’t marketing tools; they’re baseline expectations. We can also observe instances of them becoming unnecessarily arrogant in making quick decisions and becoming tools of some harmful anti-social ideological groups. However, we must understand that any generation should have proper education about certain aspects of the normal world, such as respecting others, listening to others, and living well. More interestingly, a global survey by the McKinsey Health Institute, covering 42,083 people across 26 countries, finds that Gen Z reports poorer mental health than older cohorts and is more likely to perceive social media as harmful.

Youth health behaviour in Sri Lanka reveals growing concerns in mental health and wellbeing. Around 18% of youth (here, school-going adolescents aged 13-17) experience depression, 22.4% feel lonely, and 11.9% struggle with sleep due to worry, with issues rising alongside digital exposure. Suicide-related risks are significant, with notable proportions reporting thoughts, plans, and attempts, particularly among females. Bullying remains a significant concern, particularly among males, with cyberbullying emerging as a notable issue. At the same time, substance use is increasing, including tobacco, smokeless tobacco, and e-cigarettes. These trends highlight the urgent need for targeted interventions to support youth mental health, resilience, and healthier behavioural outcomes in Sri Lanka. We need to create a forum in Sri Lanka to keep young people informed about this. Sri Lanka can designate a date (like April 25th) as a National Youth Empowerment Day to strengthen youth mental health and suicide prevention efforts. This should be supported by a comprehensive, multi-sectoral strategy aligned with basic global guidelines. Key priorities include school-based emotional learning, counselling services, and mental health training for teachers and parents. Strengthening data systems, reducing access to harmful means, and promoting responsible media reporting are essential. Empowering families and communities through awareness and digital tools will ensure this day becomes a meaningful national call to action.

As discussed earlier, Sri Lanka must carefully understand and respond to the challenges arising from its ongoing changes. Sri Lanka should establish an immediate task force comprising responsible stakeholders to engage in discussions on ongoing concerns. Recognising that it is not a comprehensive solution, the World Happiness Index can nevertheless act as an important indicator in guiding a paradigm shift in how we approach education and economic development. For a country seeking to reposition itself globally, Sri Lanka must adopt stronger, more effective strategies across multiple sectors. Building a resilient and prosperous future requires sound policymaking and clear strategic direction.

Hidden diversity in Sri Lanka’s killifish revealed: New study reshapes understanding of island’s freshwater biodiversity

Published

on

Aplocheilus parvus

A groundbreaking new study led by an international team of scientists, including Sri Lankan researcher Tharindu Ranasinghe, has uncovered striking genetic distinctions in two closely related killifish species—reshaping long-standing assumptions about freshwater biodiversity shared between Sri Lanka and India.

Published recently in Zootaxa, the research brings together leading ichthyologists such as Hiranya Sudasinghe, Madhava Meegaskumbura, Neelesh Dahanukar and Rajeev Raghavan, alongside other regional experts, highlighting a growing South Asian collaboration in biodiversity science.

For decades, scientists debated whether Aplocheilus blockii and Aplocheilus parvus were in fact the same species. But the new genetic analysis confirms they are “distinct, reciprocally monophyletic sister species,” providing long-awaited clarity to their taxonomic identity.

Speaking to The Island, Ranasinghe said the findings underscore the hidden complexity of Sri Lanka’s freshwater ecosystems.

“What appears superficially similar can be genetically very different,” he noted. “Our study shows that even widespread, common-looking species can hold deep evolutionary histories that we are only now beginning to understand.”

A tale of two fishes

The study reveals that Aplocheilus blockii is restricted to peninsular India, while Aplocheilus parvus occurs both in southern India and across Sri Lanka’s lowland wetlands.

Despite their close relationship, the two species show clear genetic separation, with a measurable “genetic gap” distinguishing them. Subtle physical differences—such as the pattern of iridescent scales—also help scientists tell them apart.

Co-author Sudasinghe, who has led several landmark studies on Sri Lankan freshwater fishes, noted that such integrative approaches combining genetics and morphology are redefining taxonomy in the region.

Echoes of ancient land bridges

The findings also shed light on the ancient biogeographic links between Sri Lanka and India.

Scientists believe that during periods of low sea levels in the past, the two landmasses were connected by the now-submerged Palk Isthmus, allowing freshwater species to move between them.

Later, rising seas severed this connection, isolating populations and driving genetic divergence.

“These fishes likely dispersed between India and Sri Lanka when the land bridge existed,” Ranasinghe said. “Subsequent isolation has resulted in the patterns of genetic structure we see today.”

Meegaskumbura emphasised that such patterns are increasingly being observed across multiple freshwater fish groups in Sri Lanka, pointing to a shared evolutionary history shaped by geography and climate.

A deeper genetic divide

One of the study’s most striking findings is that Sri Lankan populations of A. parvus are genetically distinct from those in India, with no shared haplotypes between the two regions.

Dahanukar explained that this level of differentiation, despite relatively recent geological separation, highlights how quickly freshwater species can diverge when isolated.

Meanwhile, Raghavan pointed out that these findings reinforce the importance of conserving habitats across both countries, as each region harbours unique genetic diversity.

Implications for conservation

The study carries important implications for conservation, particularly in a country like Sri Lanka where freshwater ecosystems are under increasing pressure from development, pollution, and climate change.

Ranasinghe stressed that understanding genetic diversity is key to protecting species effectively.

“If we treat all populations as identical, we risk losing unique genetic lineages,” he warned. “Conservation planning must recognise these hidden differences.”

Sri Lanka is already recognised as a global biodiversity hotspot, but studies like this suggest that its biological richness may be even greater than previously thought.

A broader scientific shift

The research also contributes to a growing body of work by scientists such as Sudasinghe and Meegaskumbura, challenging traditional assumptions about species distributions in the region.

Earlier studies often assumed that many freshwater fish species were shared uniformly between India and Sri Lanka. However, modern genetic tools are revealing a far more complex picture—one shaped by ancient geography, climatic shifts, and evolutionary processes.

“We are moving from a simplistic view of biodiversity to a much more nuanced understanding,” Ranasinghe said. “And Sri Lanka is proving to be a fascinating natural laboratory for this kind of research.”

Looking ahead

The researchers emphasise that much remains to be explored, with several freshwater fish groups in Sri Lanka still poorly understood at the genetic level.

For Sri Lanka, the message is clear: beneath its rivers, tanks, and wetlands lies a largely untapped reservoir of evolutionary history.

As Ranasinghe puts it:

“Every stream could hold a story of millions of years in the making. We are only just beginning to read them.”
