Phenotypic differences between humans and chimpanzees may be explained by the time during development when genes are turned on in humans and chimpanzees.

Question

Quizplus · Accepted Answer

There is increasing evidence that differences in gene expression during development can explain many of the phenotypic differences between humans and chimpanzees. For example, genes involved in brain development are turned on for longer periods of time during human fetal development compared to chimpanzee fetal development, potentially contributing to differences in cognitive abilities.
