Researchers reveal a complete history of primate evolution

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, represent one of the most studied and recognizable groups on Earth. But despite decades of research, scientists have only recently come close to completing a full picture of their evolutionary history. That picture (below) comes in the form of a “timetree”—a phylogenetic tree that not only shows how s
