Animal Species We Thought Were Extinct but Just Reappeared

[00:00:00]What if extinction >> [music] >> isn't always the end?

[00:00:03]For decades, sometimes even centuries, scientists have declared certain animals gone forever, wiped [music] out, lost to time. But every once in a while, something impossible [music] happens.

[00:00:15]They come back.

[00:00:17]Take the coelacanth, a creature scientists believed vanished with the dinosaurs over 65 million [music] years ago.

[00:00:23]It was known only from fossils until 1938, when a living one was pulled [music] from the ocean off the coast of South Africa.

[00:00:31]A living fossil hiding in the depths the entire time. And it's not alone.

[00:00:36]The takahē, a bright blue flightless bird from New Zealand, was declared extinct in the late 1800s.

[00:00:43]For 50 years, nothing.

[00:00:46]Then suddenly, [music] rediscovered in a remote mountain valley in 1948, quietly surviving where [music] no one thought to look.

[00:00:53]But sometimes, the rediscoveries are even more shocking.

[00:00:57]The Laotian rock [music] rat wasn't just thought extinct. It was believed to have disappeared 11 million years ago.

[00:01:03]Scientists only knew it from fossils.

[00:01:05]Then one day, it showed up being sold in a local market as food.

[00:01:10]Imagine that. An animal lost for millions of years casually reappearing on a dinner table.

[00:01:15]And here's where things get [music] even stranger.

[00:01:18]In the dense forests of Vietnam, the elusive silver-backed chevrotain, a tiny deer-like creature, vanished from scientific [music] records for nearly 30 years.

[00:01:28]Many assumed it was gone for good, until hidden camera traps captured it alive, watching, moving, surviving.

[00:01:38]It had been [music] there the whole time, just avoiding us.

[00:01:41]So, what does this really mean?

[00:01:43]>> [music] >> These animals weren't brought back. They were never truly gone. They slipped through the cracks [music] of human observation, living in remote, unexplored, or overlooked >> Mhm.
