Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found. The study ...
Octopuses and squids carry the largest nervous systems of any invertebrate, and roughly two-thirds of an octopus’s neurons ...
Predicting the evolution of white matter hyperintensities (WMH), a common feature in brain magnetic resonance imaging (MRI) scans of older adults (i.e., whether WMH will grow, remain stable, or shrink ...
Flight is a rare skill in the animal world. Among vertebrates, it evolved only three times: in bats, birds, and the long-extinct pterosaurs. Pterosaurs were the pioneers, taking to the skies more than ...
Brain size tripled in the human lineage over four million years, but why this occurred remains uncertain. Here, to study what caused this brain expansion, I mathematically model the evolutionary and ...
Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an ...
Humans, who are classified among the five great apes, are closest genetically, i.e., DNA similarity, to chimpanzees (98.8%-99%) and bonobos (98.8%). [Blueringmedia ...
An international study published in the journal Nature Mental Health has identified three psychological profiles associated with different patterns of cognitive and brain decline in aging. The study, ...
We will now discuss in a little more detail the Struggle for Existence. ―Darwin Compared with other mammals, human beings have large brains and access to types of intelligence that other animals ...
