[00:00:00]This frog spends winter with no heartbeat, dot no breathing, dot no movement. Its body becomes ice, but it is not dead. But wood froglets ice form around its organs while flooding its cells with sugar-like biological antifreeze. That sugar helps stop the ice from tearing the cells apart. Then spring arrives, the frog thaws from the inside out, dot first the heart starts, then the brain wakes, then the legs move. Dot evolution did not teach this frog to escape winter, dot it taught it how to pause death.
