WebNational Center for Biotechnology Information 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 …
