          Angry Feet: How the Emotional Body Map Changed Over Time

          Researchers analyzing 1 million Akkadian words from ancient Mesopotamian texts revealed unique insights into how emotions were experienced in the body. While many emotions align with modern perceptions, the ancients notably linked happiness to the liver and anger to the feet, contrasting with modern experiences in the chest and hands.

          How Evolution Shaped the Brain’s Understanding of Numbers

          Human number cognition may be rooted in the putamen, a deep brain structure traditionally associated with movement rather than abstract thought. Neurosurgery patients demonstrated activity in this area while processing numbers as symbols, words, and concepts, suggesting that numerical understanding emerged early in evolution.

          Gut Microbes May Have Powered Evolution of Larger Brains

          A new study suggests that gut microbes played a key role in the evolution of larger brains in primates by influencing energy production and usage. Researchers implanted microbes from humans, squirrel monkeys (large-brained species), and macaques (small-brained species) into mice, observing that microbes from larger-brained primates enhanced energy production, while those from smaller-brained primates favored fat storage.

          Human Brains Evolved Gradually, Not in Sudden Leaps

          A new study reveals that modern humans, Neanderthals, and other relatives evolved larger brains through gradual changes within each species, overturning the idea of sudden leaps in brain size. Researchers used the largest-ever fossil dataset spanning 7 million years and advanced statistical methods to reconstruct brain size evolution.

          A new AI algorithm inspired by the genome’s ability to compress vast information offers insights into brain function and potential tech applications. Researchers found that this algorithm performs tasks like image recognition and video games almost as effectively as fully trained AI networks.

          Great Apes’ Gaze Reveals Human-Like Event Perception

          Great apes track events involving agents and patients, like humans, suggesting shared cognitive mechanisms. When watching video clips, apes alternated their gaze between agents (e.g., a cat) and patients (e.g., a mouse), similar to adult humans, though apes paid more attention to background details.

          Chimpanzees Show Friendly Behaviors Are Contagious

          Grooming and play behaviors in chimpanzees are contagious, fostering social bonds and harmony within their groups. Conducted at a wildlife orphanage, the research shows how observing others’ positive actions encourages similar behaviors, with grooming occurring more often among close partners and play thriving among younger chimps.

          How AI Could Shape Human Evolution in Subtle Yet Profound Ways

          Artificial intelligence is becoming a pivotal force in human lives, prompting questions about its evolutionary effects. A new study explores how AI may influence human evolution through everyday interactions, likening human-AI dynamics to ecological relationships such as predation or competition. Potential evolutionary shifts include changes in brain size, attention spans, personality traits, and social behaviors, particularly through AI's impact on relationships and decision-making.

          How Hunter-Gatherer Kids Learn Lifelong Skills by Age Six

          Hunter-gatherer children in the Congo Basin learn critical skills like hunting, gathering, and childcare by age six or seven, thanks to a unique social learning environment. Unlike Western societies, where learning is primarily parent- or teacher-centered, these children gain knowledge from parents, peers, extended family, and unrelated adults within their small, egalitarian communities.

          Why Human Culture Never Stops Evolving

          A new study proposes that human culture’s unique power lies not in its ability to accumulate knowledge, as once thought, but in its "open-endedness." Unlike animal cultures that reach limits in evolution, human culture continuously expands, adapting without bounds.

          Chimpanzees’ Task Performance Changes When Observed by Humans

          A new study finds that chimpanzees, like humans, are affected by being watched: their performance on computer tasks improved on difficult tasks with larger human audiences but declined on simpler ones. This phenomenon, known as the "audience effect," was previously thought to be unique to humans and linked to reputation management. The results suggest that sensitivity to being observed may have evolved before human society developed its complex reputation-based social structures.
