Researchers have examined the genomes of 240 mammal species. The project reveals when mammals evolved, how some developed the ability to hibernate, and clues that may help explain humans' brains.
By comparing the genetic blueprints of an array of animals, scientists are gaining new insights into our own species and all we share with other creatures. One of the most striking revelations is that certain passages in the instructions for life have persisted across evolutionary time, representing a through line that binds all mammals – […]
The loss of about 10,000 bits of DNA over the course of our evolutionary history helped differentiate us from other mammals, a team of Yale researchers found.
