News Finding: Comparing DNA among related animals can provide a clear picture of how their shared genes evolved over time, giving rise to new and separate species, Martin said.
Paper Finding: A few observations can be made from this figure.
News Context: Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests. Comparing DNA among related animals can provide a clear picture of how their shared genes evolved over time, giving rise to new and separate species, Martin said. It can give scientists a broader perspective for interpreting data.
Paper Context: Also shown are the 95% CIs of the fossil calibrations for the crown primate and crown anthropoid nodes found from the fossil analysis (gray bars). A few observations can be made from this figure. First, there is broad agreement among all the point estimates and CIs for all the calibration models.
