Climate Changed the Size of Our Bodies and, To Some Extent, Our Brains

A new study reveals the impact climate played in the evolution of the human brain and body. Studying 300 fossils from the genus Homo found across the globe, researchers found those who lived in colder climates had larger body frames. Larger bodies provided a buffer from colder temperatures. Brain size tended to be larger in those who lived in environments with less vegetation and survived by hunting large animals, a task that involved higher cognitive function.

Breeding Foxes for Opposite Behaviors Produces Similar Brain Changes

Foxes bred to be either tame or aggressive had increased size in similar brain regions, a new study reports. The animals bred for specific behavioral traits had larger brains than those that were conventionally bred. The findings contradict existing theories of animal domestication.
