The average adult human brain weighs 1.3kg (2.8lb). That's twice the weight of a giraffe's brain and three times the weight of a cow's brain. A newborn human baby has a brain that...
A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larg...
In a groundbreaking revisit to a longstanding debate in evolutionary biology, a new study authored by Robin Dunbar of the University of Oxford has reignited discussions about the d...
Our brains are large compared with other animals, so it is tempting to assume there was an evolutionary advantage to them – but that may not be true at all
Jan Bartek - AncientPages.com - A new study challenges established views on human skull evolution. Researchers suggest that brain growth and the reduction of the face and jaw may b...
Octopuses, squid and cuttlefish may have evolved large brains because of the challenges posed by their environments rather than the demands of social life, according to a new study...
A new study has uncovered a fundamental link between brain size and offspring size, helping to solve a long-standing evolutionary puzzle: Why do birds lay such disproportionately l...
A new study utilizes molecular genetic timelines to validate the "brain lag" hypothesis, proving that primate body growth preceded brain expansion. The analysis expands the theory...
A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size...
Human body size evolution was not a linear progression. Instead, a massive body mass explosion occurred 2 to 2.5 million years ago with Homo erectus, while divergent species like H...
A spatial single-cell brain atlas of the jawless lamprey reveals that the common ancestor of all vertebrates possessed a highly complex molecular brain architecture 450 million yea...
It is a myth that humans only use a fraction of their brains. Even though scientists are still trying to unravel the mysteries of the human mind, every part of the brain is known t...
This is tantamount to saying the human brain, chief marvel in the cosmos as far as we can tell, evolved because, well, why the heck not? Source
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant br...
A study published in Neuroscience by researchers at Spain's University of Zaragoza scanned the brains of 100 young adults and found structural differences in those who hold authori...
