Bonobos“Chimpanzees brought up in a home do not speak, think, or act like people, and that is because of the information in the ten megabytes of DNA that differ between us. Even the two species of chimpanzees, common chimps and bonobos, which differ in just a few tenths of one percent of their genomes, part company in their behavior…. Common chimps are among the most aggressive mammals known to zoology, bonobos among the most peaceable.”—The Blank Slate: The Modern Denial of Human Nature, Steven Pinker, p.45
