Why Declaring Species Extinct Is a Dangerous Mistake: Lessons from the Thylacine and Mammoth

Discover why officially declaring a species extinct can be a detrimental act, stripping away vital protections and potentially overlooking hidden survivors. This post explores the biological and ethical implications, using the Tasmanian Tiger and the Mammoth as prime examples of species that might still roam the wild.

The Perilous Act of Declaring Extinction

In the realm of biology and conservation, the word "extinct" carries immense weight. It signifies finality, the irreversible loss of a unique branch on the tree of life. However, as the "Broadcasting Seeds Podcast" episode "Flashback Friday with Mr. E from Cryptids of the Corn" subtly suggests, the definitive declaration of extinction might be a premature and even dangerous act. When a species is officially declared extinct, it is stripped of all legal protections. This means that any remaining individuals, if they exist, have no legal standing to prevent their exploitation, capture, or further endangerment. This crucial point underscores the importance of maintaining the 'critically endangered' status, which, according to the IUCN Red List, is the highest designation before a species is considered extinct. This classification ensures that conservation efforts can continue and that these vulnerable populations remain under a watchful eye, even if their numbers are critically low.

Conservation Implications of Extinction Declarations

The decision to declare a species extinct is not merely an academic exercise; it has profound real-world consequences for conservation. Once a species is gone, at least officially, the impetus for protecting its habitat or actively seeking out its remaining numbers often diminishes. This is particularly concerning for species that are naturally reclusive, inhabit remote or unexplored regions, or have adapted to avoid humans due to past persecution. The argument presented by Mr. E in the podcast is that many of these creatures may not be gone, but simply incredibly good at hiding. The history of zoology is dotted with instances of species being "rediscovered" after long periods of presumed absence. These rediscoveries often occur in areas that are difficult for humans to access or survey thoroughly. Therefore, by declaring a species extinct, we might be inadvertently closing the door on the possibility of its continued existence and the critical conservation efforts that could save it.

Case Study: The Thylacine, A Shadow of Survival

The Tasmanian Tiger, or Thylacine, is a prime example of a creature whose official extinction is still debated by many. Once widespread across Australia, Tasmania, and New Guinea, its numbers plummeted due to hunting, bounties, and habitat loss. The last known individual died in captivity in 1936. However, persistent anecdotal evidence and alleged sightings continue to surface, suggesting that small, elusive populations might still exist in the rugged, unexplored wilderness of Tasmania. Mr. E highlights that the very traits that made the thylacine vulnerable – its shy nature and ability to avoid humans – could also be the reasons for its potential survival. The intense hunting pressure likely led to a form of selective breeding, favoring the individuals that were most adept at hiding. If any thylacines survived, they would likely be found in the vast, challenging terrains where human presence is minimal, allowing them to continue their existence undetected.

Selective Pressure and Hidden Populations

The concept of selective breeding plays a crucial role in understanding how species might persist against the odds. An analogy is drawn to rattlesnakes in Texas that have reportedly stopped rattling. This isn't because the gene for rattling has disappeared, but rather because individuals that *didn't* rattle were less likely to be killed by humans who feared them. Over time, the non-rattling trait became more prevalent, especially in areas with high human activity. Similarly, the thylacine, a marsupial predator, was a target for farmers and hunters. The shyer, more secretive individuals that were less prone to confrontation or discovery would have a higher chance of survival and reproduction. If these traits are heritable, it's plausible that a population could have evolved to be even more adept at evading detection, making them exceptionally difficult to find and confirm.

Mammoths and the Cost of De-Extinction

The discussion also touches upon the ambitious de-extinction projects, such as those proposed by Colossal Biosciences, aiming to bring back species like the Mammoth, Thylacine, and Stellar Sea Cow. While technologically fascinating, Mr. E raises a critical question about priorities. He suggests that the vast sums of money and resources poured into de-extinction could potentially be better allocated to conserving existing endangered species and their habitats. Furthermore, he posits that species like the Mammoth might not be entirely extinct. Frequent alleged sightings in remote regions of Siberia and the Yukon, areas that remain prime Mammoth habitat, lead him to wonder if existing populations, perhaps smaller or more elusive than historically understood, could still exist. It's a thought-provoking contrast: spending billions to recreate a species versus investing in finding and protecting potentially living individuals. The idea that it might be more cost-effective to discover existing Mammoths in remote areas than to engineer them from scratch is a powerful critique of current de-extinction trends.

Unexplored Habitats and Hidden Biodiversity

The Earth's remaining wild places, particularly dense rainforests, vast mountain ranges, and remote oceanic depths, are still largely unexplored. These environments harbor incredible biodiversity, and it's highly probable that many species remain unknown to science. The podcast episode implies that creatures we consider cryptids or extinct might simply be inhabitants of these hard-to-reach locales, perfectly adapted to avoid human detection. The Australian continent, with its vast, rugged interior and dense, ancient rainforests, is a prime example. It's a place where unique flora and fauna have evolved in isolation, and where the possibility of discovering unknown or rediscoverable species remains high. The survival of shy creatures like the thylacine, or even potentially larger, more elusive mammals, is entirely plausible within these less-traveled frontiers.

The Importance of Keeping an Open Mind

Ultimately, the conversation with Mr. E serves as a potent reminder that our understanding of the natural world is incomplete. The line between myth, legend, and biological reality is often blurred. By dismissing reports of cryptids or alleged survivors of "extinct" species out of hand, we risk overlooking genuine biological wonders and critical conservation opportunities. The episode encourages listeners to approach these topics with a blend of scientific rigor and open-minded curiosity, acknowledging that the natural world is far stranger and more mysterious than we often admit. The possibility that a species declared extinct might still be out there, living in the wild, is a testament to the resilience of life and the vastness of the unknown.
