Did Climate Change drive Human Evolution?

Habitats kept changing because climates kept changing. Centuries of drought, for example, would shift to centuries of monsoons, over and over. Which raises a question, Potts says: "Not how did humans become adapted to a specific ancestral environment, but how did we become adaptable?" Extraordinarily adaptable to so many different environments.

"And that's a totally new question," he says, "one that Darwin never really addressed."

Potts is one of the authors of the National Academy of Sciences report, and proposes that it was flip-flopping climate that sparked some of our biggest evolutionary adaptations — the invention of better tools, for example, or a bigger brain.

  • We adapt we don't evolve. Humans will never be anything but human.

  • Yes, climate change drove humans to migrate, develop new skills, and adapt to new kinds of food, different kinds of lifestyles and behaviors. It's still happening. Humanity isn't stagnant.

  • Yes it has everything to do with it. Also evolve does not necessarily only refer to change from human to something completely diff.
