"There are many paleontologists and molecular biologists who are heaping scorn on this paper," noted Peter Andrews of the Natural History Museum in London.Įven though he still backs the human-chimp relationship, Andrews had recommended that the study be published, and it now appears in the June issue of the Journal of Biogeography. The finding, which has the potential to spark a radical rethink of human origins, is being met with caution. What's more, the genetic similarities likely include many ancient DNA traits that are shared across a much broader group of animals.īy contrast, humans share at least 28 unique physical characteristics with orangutans but only 2 with chimps and 7 with gorillas, the authors say. John Grehan, of the Buffalo Museum of Science in New York State, and Jeffrey Schwartz, of the University of Pittsburgh in Pennsylvania, say that the DNA evidence cited by many scientists only looks at a small percentage of the human and chimp genomes. What's more, the study authors argue, the genetic evidence itself is flawed. The authors base their conclusion on a close physical resemblance between orangutans and humans, which they say has been overshadowed by genetic evidence linking us to chimps.
Orangutans, not chimpanzees, are the closest living relatives to humans, a controversial new study contends.
