Early Humans' Brains Were More Apelike than Modern

Very recommendable! The long held belief that the first hominids to leave Africa were intelligent and had a large brain was too nice! Of course, Homo erectus (the upright hominin) must have had a rather modern brain!

Even today, human brains still seem primitive! How else can you e.g. explain the highly irrational, extreme, and very long lasting global overreaction to the fairly harmless SARS-Cov-2 virus? Pardon, my sarcasm!

"... Here, we show that the brains of early Homo from Africa and Western Asia (Dmanisi) retained a primitive, great ape–like organization of the frontal lobe. By contrast, African Homo younger than 1.5 million years ago, as well as all Southeast Asian Homo erectus, exhibited a more derived, humanlike brain organization. Frontal lobe reorganization, once considered a hallmark of earliest Homo in Africa, thus evolved comparatively late, and long after Homo first dispersed from Africa. ..."

Early Humans' Brains Were More Apelike than Modern | The Scientist Magazine® Impressions that ancient brains left in fossilized skulls reveal that the first human ancestors to migrate out of Africa had much more primitive brains than previously thought.
