Although large male chimpanzees can exceed any bonobo in bulk and weight, the two species actually broadly overlap in body size. Source: Internet
As human populations grow, so does the risk of disease transmission between humans and chimpanzees. Source: Internet
As our closest relatives, chimpanzees have a lot of potential to tell us about mechanisms of disease (and what genes may be responsible for human intelligence). Source: Internet
