Human evolution is weird because the story only feels inevitable after it already happened.

Dinosaurs ruled the planet for an amount of time our brains cannot really hold. Then an asteroid hit the Yucatán, the world changed, a bunch of life disappeared, and tiny mammals got their opening.

Very normal way to start the family tree.

In this episode of Maxwell’s Kitchen, I talk with Stephen Frost, a professor of anthropology at the University of Oregon, about human evolution, primate evolution, extinction events, fossils, climate change, intelligence, social behavior, and why humans ended up here at all.

We talk about the Chicxulub impact, the extinction of the dinosaurs, why mammals survived, how primates evolved, why walking on two legs mattered, why big brains are expensive, how emotions may have helped humans survive, and why evolution is not the same thing as happiness.

This conversation also gets into agriculture, fire, tools, human teeth, brain size, social intelligence, soap operas, iPhones, Mars colonies, dinosaurs, fossils, Sasquatch, UFOs, the moon landing, and why science keeps changing what we think we know.

• Sasquatch, UFOs, and evidence
• Why science keeps changing

Guest:
Stephen Frost is a professor of anthropology at the University of Oregon. As a paleontologist and paleoanthropologist, his work focuses on human and primate evolution, African monkeys, biological shape, climate change, and what past ecosystems can tell us about the history of life on Earth.
