Discovering Tanzania’s chimpanzees
Scientist Jane Goodall landed in Tanzania’s Gombe Stream National Park in 1960 and spent years living among and observing the park’s chimpanzees. The research program she founded upon arriving is still in operation, making it the longest running study of wild animals in the world. Here, Goodall observes a group of chimps grooming each other.
