Humans did not evolve from chimps, as is a frequent misconception. Chimpanzees and humans share a recent common ancestor , and as some of this ancestral population evolved along one line to become modern chimpanzees, others of this ancestor evolved along a line of various species of early human, eventually resulting in Homo sapiens you and me!
Chimpanzees are genetically closest to humans, and in fact, chimpanzees share about We share more of our DNA with chimpanzees than with monkeys or other groups, or even with other great apes! We also both play, have complex emotions and intelligence, and a very similar physical makeup.
What many people may also not know, is how vital this taxonomy or the systematic classification of organisms is to Dr. It was in fact Dr. Louis Leakey in Kenya, which lead to her initial research in Gombe, Tanzania. Leakey was trying to understand early humans, and because his only point of reference was fossilized early human remains and other preserved cultural materials, he could not completely understand what early human behavior may have been like. When he met Jane, with her passion for and knowledge about animals, he knew she would be the perfect candidate to study chimpanzees — our closest living primate relative — from which he could conclude what behaviors were likely inherent to our most recent common ancestor and earlier humans.
Zinda fishing for termites in Gombe National Park, Tanzania. In her research, Dr. Goodall made a revolutionary discovery when she observed that the chimps in Gombe were making and using tools.
It was groundbreaking because it meant redefining everything that scientists thought they knew about what separated humans and chimpanzees! It has also lead to the revelation that other animals also make and use tools, have emotions, intelligence and sentience.

See how people have imagined life on Mars through history. They live south of the Congo river, , and have not been split into any sub-species. As a highly adaptable species, chimpanzees inhabit a range of habitats, including tropical rainforest, montane rainforests at altitudes of up to m, swap forests, less densely vegetated forest-savannah mosaics, and even dry savannah. The oldest recorded chimpanzee was Little Mamma, a captive female who was between 76 to 82 years old when she died in This record holder far exceeds the median life expectancy for captive chimps, which is This is nearly twice as old as has been found for other chimpanzee groups, and about the same as the average lifespan of human hunter-gatherers.
But the Ngogo group is not a typical one. Unlike other groups studied, it inhabits a productive, healthy forest with low levels of human disturbance, so it might be a more accurate reflection of natural chimpanzee lifespan.
Chimpanzees get around by climbing and swinging through trees and by walking on all fours knuckle-walking , but they can also walk upright on two feet if they want to. Toxoplasma gondii is a microscopic single-celled cat parasite that also infects a range of other mammals and birds as intermediate hosts, forming cysts in their brains and other organs.
These hosts must be eaten by a feline if the parasite is to complete its life-cycle, and research in Gabon has shown that infected chimps develop an attraction to the smell of leopard urine.
That would mean the parasite is directly manipulating its chimpanzee host into increasing its chances of being killed by a leopard, enabling the parasite to complete its own life cycle. Chimpanzees live in fission-fusion societies, meaning that the size and composition of their social groups changes over time.
Although they are very seldom seen together at one place, within these multi-male, multi-female communities all members know each other individually and they defend a common home range together. Communities may consist of up to individuals but have strict hierarchies, with normally just one dominant alpha male.
Females will reach reproductive maturity by age 13 and can give birth at any time of the year. Although not seasonal breeders females do have an oestrous cycle, and the number of oestrus females in a group at any one time can vary by season.
