Always wanted to climb a tree to take a picture. Always liked kind of the elevated perspective. George Steinmetz: And he was sure that he was gonna die out there.
selection is you have these animals and they and you know and and they reproduce and you get this very very slight variation and then the variants that do better uh uh give rise to more offspring. The ones that do worse die out and through this slow gradual accretion you end up with different species and different organs and different capacities. That's the Darwinian story of natural selection. But Goldmith said there's something else. Sometimes he argued there are extreme mutations and these extreme mutations lead to radical changes in creatures and most of the

The more I was researching, the more it became clear that there were commonalities between these different mass extinction events. And I should say, there have been plenty of other extinction events, by the way, where only say 30% or 40% of all species on the planet die out , which is already a huge catastrophe.
Asteroids from space, pretty good on the exciting scale. But generally, when you start having these climate changes, the reason why animals die out is because of famine and starvation. It's really simple. When you start having habitats change, food sources become less and less available.
