Genetic analysis traces previously unknown primate hybridization
Like lipstick on a collar, new DNA evidence is pointing to ancient affairs between bonobos and chimpanzees.
Chimps carry a small percentage of bonobo DNA, researchers report in the Oct. 28 Science. The conclusion comes from analysis of the genetic instruction books, or genomes, of 63 wild-born chimps, two captive chimps named Clint and Donald, and 10 wild-born bonobos. The apes came from 10 African countries.
