Chimpanzee and human divergence occurred
WebJan 23, 2024 · The first study estimated the mutation rate to be much smaller than anticipated, around 0.43 in a billion changes per year and later studies have confirmed this rate using several thousand human trios. Using this rate the human-chimpanzee speciation time becomes around 10 million years and this appears at odds with the fossil … WebThe sequence divergence varies significantly between humans, chimpanzees and gorillas. For most DNA sequences, humans and chimpanzees appear to be most closely related, but some point to a human-gorilla or chimpanzee-gorilla clade. The human genome has been sequenced, as well as the chimpanzee genome.
