Argentina’s 19th-Century Cholera Outbreaks Show the Myth of a Single, Definitive Conclusion

For decades, scientists have heralded the idea that human brains have increased in size over the course of history, evolving in modern humans be much larger than that of our Neanderthal cousins. In October 2021, DeSilva et al., seemingly added more evidence to this hypothesis with a paper that concluded the human brain shrank during the transition to modern urban societies about 3,000 years ago. And while this supported previous literature, the research did establish a new timeline—marking brain decrease as late as the last Ice Age.

Anthropologists believe that brain size has remained dynamic in size. It nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age.
