00:00Nature's True Phoenixes
00:01Beings reborn from the ashes, nature is full of extraordinary phenomena, and resilience is one of the most impressive.
00:09Although the story of the phoenix, a bird reborn from its own ashes, is a myth.
00:15Science has revealed that the ability to survive and thrive in extreme heat is an astonishing reality.
00:21Today, we will show you some of the true phoenixes of the natural world.
00:26Let's start in the most inhospitable places, in the depths of the ocean or the boiling waters of a geyser.
00:33Here, live hyperthermophiles, microorganisms that not only withstand heat, but need it to live.
00:41These single-celled organisms, mostly archaea, thrive at temperatures exceeding 120 degrees Celsius,
00:48a mark where most life forms would simply disintegrate.
00:52But how do they do it?
00:53Archaea have evolved molecular tricks that keep their proteins stable,
00:58a biological shield that allows them to survive where no one else could.
01:04They are the ultimate champions of heat survival.
01:07But resistance is not exclusive to the microscopic world.
01:11In the animal kingdom, we find weevils in South Africa,
01:15small insects that live in an area prone to wildfires.
01:17The question was, how do these tiny, flightless creatures survive an inferno of flames?
01:24Scientists discovered that these weevils have an incredible heat tolerance,
01:29with some species enduring temperatures up to 53 degrees Celsius.
01:34It is believed that they have molecular adaptations,
01:37or that they burrow into the soil to escape the fire.
01:40But the story doesn't end there.
01:43Some weevil species have their own version of the Phoenix-esque rebirth.
01:46They lay their eggs inside plants with tough,
01:50woody exteriors that resist the fire.
01:53When the fire is over, the eggs hatch from the ashes.
01:57It is a life lesson that shows that resilience is as natural as destruction itself.
02:01These examples remind us that, although the legend of the Phoenix is a fantasy,
02:06life's ability to be reborn and persist is an undeniable fact.
02:11From the tiny hyperthermophile to the weevil that rises from the ashes.
02:16Nature teaches us that fire can be the end,
02:19but also the beginning of something new.
