A study published in the journal Current Biology points out that it is a segment of human DNA which is responsible for large human brains. For the new study, researchers explored databases of genomic data from humans and chimpanzees, in order to find enhancers expressed primarily in the brain tissue and early in development.

The finding is crucial in understanding the role a segment of DNA plays in distinguishing human evolution from other animals. Researchers said that they observed a greater increase in the size of brains in mice in case of a human version of a specific enhancer involved in brain development as compar...
