A new study reveals the impact climate played in the evolution of the human brain and body. Studying 300 fossils from the genus Homo found across the globe, researchers found those who lived in colder climates had larger body frames. Larger bodies provided a buffer from colder temperatures. Brain size tended to be larger in those who lived in environments with less vegetation and survived by hunting large animals, a task that involved higher cognitive function.
Human near-death experiences may have arisen from an evolutionary mechanism, researchers report.
The recently discovered Homo longi lineage may be our closest relative. The findings have the potential to reshape our understanding of human evolution.
Foxes bred to be either tame or aggressive had increased size in similar brain regions, a new study reports. The animals bred for specific behavioral traits had larger brains than those that were conventionally bred. The findings contradict existing theories of animal domestication.
The Tsimane, an indigenous people from the Bolivian Amazon, have less brain atrophy than American aging adults, a new study reports. Additionally, the decrease in their brain volume associated with aging is 70% less than seen in older American adults.
Combining brain imaging data with machine learning, researchers make new discoveries about how the brain controls the hand. The findings could lead to the development of more advanced neuroprosthetics.
The cerebellum underwent evolutionary changes that may have contributed to the development of language, culture, and tool use in humans, a new study reveals.
Some traditional masculine stereotypes, such as being adventurous and competitive, were linked to being better fathers to infant children. This is especially true if men also adopt a nurturing role. However, one trait, hostile sexism, was not linked to improvements in parenting skills.
Computer tomography reveals modern human brain structures only originated between 1.5 to 1.7 million years ago in African Homo populations.
A new technique which involves fusing human and chimpanzee skin cells that have been modified to act like stem cells, allowed researchers to identify two novel genetic differences between humans and chimps.
