Mouse embryos have developed massive, fast-growing brains after receiving a dose of human DNA in the womb. Scientists suspect that the gene encoded by this DNA is what separates us from all other animals. Humans would be nothing without our remarkable brains. Despite sharing 98 percent of our DNA with chimpanzees, we’ve got much bigger brains, and they undergo a massive white matter growth explosion in the first two years of life, which means a super-fast proliferation of neural connections. Researchers have pinned this to why we’re so much more intelligent than our primate brethren, but it’s not actually clear where in our genetic make-up the instructions to make all this occur.
