The following is an excerpt.
A new genome-wide analysis, led by the University of Chicago Medical Center, searched for evidence of long-lived balancing selection – where the evolutionary process acts not to select the single best adaptation but to maintain genetic variation in a population. The study revealed at least six regions of the genome where humans and chimpanzees share the same combination of genetic variants.
The results of this study have been published in a recent issue of Science.
