The Tolerant Brain: What Macaque Amygdalae Tell Us About the Evolution of Social Life A new study scanned the brains of 12 macaque species and found that tolerance, not aggression, predicts amygdala size — and the developmental story is stranger than expected.

New research scanned brains across 12 macaque species and found tolerant societies — not aggressive ones — predict larger amygdalae, with inverted developmental trajectories that flip the standard primate pattern. #Primatology #BrainEvolution #SocialBrain www.primatology.net/p/the-tolera...

4/11 Early ancestors' brains kept growing larger and more complex, but failed to reach maturity in the womb.

Babies emerged less mature than other species - deeply vulnerable and demanding constant care.

Our big brains may have evolved because of placental sex hormones Unlike other primates, humans are exposed to high levels of placental sex hormones in the womb, which may have shaped our evolutionary brain development

Why did humans evolve big brains? A new idea bodes ill for our future Recent fossil finds suggest that big brains weren't an evolutionary asset to our ancestors but evolved by accident – and are likely to shrink again in the near future

An interesting and thought-provoking article about the evolution of the brain, its size, and the theories on why it began to shrink millennia ago—possibly triggered by social and “technological” advances.
