Modern humans evolutionarily split from our chimpanzee ancestors nearly 7 million years ago, yet we are continuing to evolve. 155 new genes have been identified within the human lineage that spontaneously arose from tiny sections of our DNA. Some of these new genes date back to the ancient origin of mammals, with a few of these “microgenes” predicted to be associated with human-specific diseases. This work was published on December 20 in the journal Cell Reports.
