Scientists found that a piece of human DNA greatly enlarges the brain of laboratory mice when inserted during their embryonic period. The researchers hope that the discovery would shed a new light on what exactly makes us different from other species on a biological level.

The piece of genetic code, dubbed HARE5, is a piece of human DNA that controls the genes around it. Evolutionary scientists are over trilled with the new finding since they hope that they will be able to better understand how the human brain evolved to such a size over the past millions of years.
