Molecular Clocks: Determining the Age of the Human–Chimpanzee Divergence
Key Takeaways:
The molecular clock hypothesis proposes that nucleotide changes occur at a regular rate during evolution.
Applying the molecular clock to sequence divergence among living species can provide an estimate of the time of the divergence of these species.
Estimates of the human–chimpanzee divergence using the molecular clock have ranged from less than 3 million to nearly 12 million years ago (Ma).
Most reliable estimates of the human–chimpanzee divergence range from 5 to 8 Ma.
Considering the various sources of uncertainty associated with molecular dating, in general the dates are in agreement with palaeontological data.
