In a recent study, researchers transplanted gut microbes from large-brained primates into mice, revealing that these microbes boosted the host's energy production for the brain, while those from smaller-brained primates promoted fat storage. This groundbreaking finding suggests that the secret to our big brains might be in our gut, pointing to a profound link between our inner bacteria and human evolution.

Recent archaeological evidence suggests that early hominins, like *Homo erectus*, may have controlled fire and cooked food as far back as 780,000 years ago, drastically reshaping their evolutionary path. The 'cooking hypothesis' argues this innovation was a pivotal turning point in human history, driving significant biological and social changes.
