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 https://www.primatology.net/p/the-tolerant-brain-what-macaque-amygdalae
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.

Relevance for mental health professionals: The study highlights prenatal hormonal milieu, inferred from finger-length ratios, as a possible influence on early brain development. For clinicians focused on developmental trajectories, this work adds a biologically grounded context for variability in neurodevelopment that may shape later cognitive and behavioral patterns. A notable finding is that higher prenatal estrogen was linked to larger head size in newborn boys, suggesting sex-specific developmental pathways relevant to understanding early risk indicators.

Early humans thrived on carbs to develop smarter brains 🌱🧠✨

Forget the paleo myth that meat fuelled human brain development—research shows that carbohydrates played a far more crucial role! Studies reveal:

✅ Early humans consumed starch-rich diets over 100,000 years ago, providing the glucose essential for brain growth.

✅ Genetic evidence of starch digestion dates back 800,000+ years, well before agriculture.

✅ Ancient populations relied heavily on plant-based foods.

The science is clear: plants powered the evolution of human intelligence. 🌱💡

T. Rex not a "clever girl" in new research - fullSTEAMahead365

A 2022 study published in the The Journal of Comparative Neurology asserted that the Tyrannosaurus Rex, or T. Rex, had up to three billion neurons, equivalent to an intelligent primate such as a baboon, leading to the possibility that they could hunt in packs, pass down knowledge, and even use tools. A new study published in The Anatomical Record, disputes this finding.

All animal intelligence was shaped by just 5 leaps in brain evolution
In an article published today in Proceedings of the Royal Society B, we argue the evolution of all these kinds of animal intelligence has been shaped by just five major changes in the computational capacity of brains.
Each change was a major transitional point in the history of life that changed what types of intelligence could evolve.
