Chimpanzees may have been using stone "hammers" as long as 4,300 years ago. An international research team, led by archeologist Julio Mercader of the University of Calgary in Canada, said Monday that it had uncovered the hammers, dated to that time, in the West African country of Ivory Coast. It would be the earliest known use of tools by chimpanzees.
A 3-year-old male chimpanzee accidentally strangled himself while playing with a rope Friday at the Los Angeles Zoo, officials said. Jamal, a playful and "typical little kid chimp," was tugging on a 4-inch-thick nylon rope when he tore a strand loose and wrapped it around his neck and head, said Jennie McNary, the zoo's principal animal keeper. "The keepers are just devastated by this loss," she said. Officials said they removed the rope and a similar one in the orangutan exhibit.

In the more than two decades since the U.S. government declared chimpanzees in the wild to be an endangered species, not much has improved for those great apes. The threats of habitat loss, poaching and disease have only intensified. Now, the U.S. Fish and Wildlife Service has proposed reclassifying captive chimpanzees as well, moving them from the "threatened" category to "endangered," a change that brings with it stricter guidelines covering the handling and use of the animals. In the future, any procedure that harms, harasses or kills a research chimp would require a permit.

Scientists have found two chimpanzees infected with a virus very similar to the human AIDS virus, providing the most valuable clue yet in the search for the mysterious origin of the deadly disease. French researchers said they detected a virus resembling the human immunodeficiency virus or HIV in two wild, baby chimpanzees captured in Gabon, an African nation that straddles the Equator.

All they needed was a getaway ark. Four chimpanzees, aided by a hard rain that toppled a tree branch in their refuge, escaped from confinement at the Los Angeles Zoo on Saturday. But after the escape forced the zoo's closure for almost an hour, the chimps were captured inside the grounds and returned to their home in the Africa section. "I can't think of the last time we had to do that," zoo spokeswoman Lora LaMarca said of the closure, which began about noon.

Minnie, the last surviving "astro-chimp" from the early days of the space program, has died at age 41. Once an understudy for the space-going chimpanzees Ham and Enos, Minnie died March 14 of old age, Coulston Foundation spokesman Don McKinney said. The private medical research lab has overseen the space chimps at Holloman Air Force Base since 1993. Minnie was the only female chimp trained for the Mercury Project in the early 1960s, but she never flew.

Male chimpanzees prefer to have sex with older females, U.S. researchers have found. Male chimps chase down and fight over the oldest females, anthropologist Martin Muller and colleagues at Boston University reported this week in the journal Current Biology. Older female chimps are more dominant socially and have access to better food and are therefore more likely to conceive, Muller said.

The baby boom at the Los Angeles Zoo is now complete, with the last of three mysteriously impregnated chimpanzees giving birth to a healthy four-pound male this week. The chimp was born Monday to Regina, 15, whose pregnancy, like that of two other females, surprised zookeepers; the male chimps in their exhibit have had vasectomies, are too young or seem uninterested. DNA tests are pending to determine paternity.

"The first thing I'm going to give you is a chimpanzee greeting, because it sounds lovely in a place like this," said Jane Goodall while looking out from a stage in Griffith Park across a meadow containing 1,000 people. Her voice started off soft and low: "Oooo, oooo, oooo...." Then her voice rose: "Hooo, hooo, HOOO! HOOO!" She finished with a smile, leaving her audience stunned for a second before they burst into applause.

State regulators have decided to renew the operating permit of an animal sanctuary where two chimpanzees attacked a 62-year-old man. Under conditions of the permit, the owners of Animal Haven Ranch near Bakersfield cannot obtain any new animals and the public is prohibited from visiting the facility, said Steve Martarano, spokesman for the state Department of Fish and Game. Two chimps escaped from a locked cage at the sanctuary March 3 and mauled St. James Davis of West Covina.
