Ancient Skulls Unveil Secrets of Human Bipedalism

A recent study using three-dimensional CT scans of the 6-million-year-old ape, Lufengpithecus, offers new insights into the evolution of human bipedalism. By analyzing the ape's bony inner ear region, researchers discovered a connection between its semicircular canals and locomotor behavior, suggesting a three-step evolution of human bipedalism from ancestral arboreal and terrestrial movements.

Ancient DNA Reveals Secrets of High Modern Alzheimer’s and MS Rates

Researchers have created a vast gene bank from nearly 5,000 ancient humans, offering unprecedented insights into the historical spread of genes and diseases. This groundbreaking study linked the spread of multiple sclerosis (MS) genes to ancient migrations and discovered that genes increasing the risk of diseases like Alzheimer's originated from hunter-gatherers.

Did Fermentation Drive Human Brain Evolution?

Recent research proposes that fermentation, rather than cooking, was the crucial dietary change that enabled the significant growth of the human brain. The researchers argue that pre-digested, fermented foods provided more accessible nourishment, bridging the gap between the evolution of larger brains and the later advent of cooking.

Human Brain Development: Growth After Birth Challenges Previous Assumptions

A new study challenges the belief that human newborns have significantly less developed brains compared to other primates. The research reveals that human infants are born with brains typical of similar primate species, but their brains grow larger and more complex post-birth, giving the impression of underdevelopment.

This shows a brain that looks like a tree.
