One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

The brain is the most complex organ in the human body. Now, a new study has brought us closer to understanding some of its evolution. It shows that human brains decreased in size approximately 3,000 ...

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 ...

Until Homo floresiensis was discovered, scientists assumed that the evolution of the human lineage was defined by bigger and bigger brains. Via a process called encephalization, human brains evolved ...

Researchers have used a new human reference genome, which includes many duplicated and repeat sequences left out of the original human genome draft, to identify genes that make the human brain ...

Data from a new study links a pair of duplicated genes to human brain features. The research provides a roadmap for scientists to gain a deeper understanding of brain function and evolution, as well ...

Until Homo floresiensis was discovered, scientists assumed that the evolution of the human lineage was defined by bigger and bigger brains. Via a process called encephalization, human brains evolved ...

Scientists uncover how finger-length ratios in newborns reveal hormonal influences that may have shaped human brain evolution.
