Human beings used to be defined as “the tool-maker” species. But the uniqueness of this description was challenged in the 1960s when Dr. Jane Goodall discovered that chimpanzees will pick and modify grass stems to use to collect termites. Her observations called into question homo sapiens‘ very place in the world. Since then scientists’ knowledge of animal tool use has expanded exponentially.
Global climate change could cause Africa’s Lake Victoria, the world’s largest tropical lake and source of the Nile River, to dry up in the next 500 years, according to new findings funded in part by The Leakey Foundation. Even more imminent, the White Nile — one of the two main tributaries of the Nile — could lose its source waters in just a decade.
