Say hello to cousin Bonzo Associated Press Washington — Chimpanzees are more closely related to people than to gorillas or other primates and probably should be included in the human branch of the family tree, a research team says. The idea, sure to spark renewed debate about evolution and the relationship between humans and animals, comes from a team led by Morris Goodman at Wayne State University School of Medicine in Detroit. Currently, humans are alone in the genus Homo. But Dr. Goodman argues, "We humans appear as only slightly remodeled chimpanzee-like apes." He says humans and chimps share 99.4 per cent of their DNA, the molecule that codes for life. The report is being published in Tuesday's on-line issue of Proceedings of the National Academy of Sciences. The battle over how humans are related to chimps, gorillas and other monkeys has raged since 1859, when Charles Darwin described evolution in On the Origin of Species. Dr. Goodman's team didn't address evolution directly but proposed that humans and chimps be considered branches of the same genus because of their similarities. A genus is a group of closely related species. The human species, Homo Sapiens, stands alone in the genus Homo. But there have been other species on the branch, such as Homo neanderthalensis, or Neanderthal man. Chimpanzees are in the genus Pan along with bonobos, or pygmy chimpanzees. Dr. Goodman's proposal would establish three species under Homo. One would be Homo (Homo) Sapiens, or humans; the second would be Homo (Pan) troglodytes, or common chimpanzees, and the third would be Homo (Pan) paniscus, or bonobo chimpanzees. There is no official board in charge of placing animals in their various genera, and in some cases alternative classifications are available. "If enough people get agitated by this and think it's something to be dealt with there may be a symposium that takes this as the central issue and determines if this is a reasonable proposal," Dr. Goodman said. "I think it's a reasonable proposal, of course, or I wouldn't have proposed it." Reclassification of chimpanzees would cause major changes in the way anthropology students learn the relationships between various types of animals, an area already involved in the debate between evolution and creationism. Walt Brown of the Center for Scientific Creation in Phoenix, Ariz., argues that since the sequencing of human and chimpanzee DNA is not complete, saying people and chimps are that much alike is "baloney." "We have similarities with chimpanzees, but there are a heck of a lot of differences too," Dr. Brown said. In their study, Dr. Goodman and colleagues compared 97 genes from humans, chimpanzees, gorillas, orangutans, Old World monkeys and mice. Genes from humans and chimps most closely resembled each other, followed by orangutans and Old World monkeys. None of the other creatures was closely related to mice.
