Bipedalism is key for humans, but we are the only living primate that has this trait. Give yourself a point if you selected (c) on this list. Question: Key adaptive traits of primates include which of the following?Ī) Bipedalism and grasping hands (opposable thumbs)ī) Bipedalism, grasping hands, and forward facing eyesĬ) Grasping hands, forward facing eyes, and collarbone.ĭ) Grasping hands, forward facing eyes, collarbone, and language. If you saw the following multiple choice question on an exam what answer would you choose? The basic question poised by this approach is this: How does the ecology that a species lives in shape its behavior? A similar question also gets considered in an evolutionary framework by those studying fossil primates: How might the past environment that a species lived in shape their anatomical and other adaptations? Common Primate Traits Ham the Astrochimp survived his flight.īehavioral Ecology is a primary theoretical orientation for understanding primate behavior. By 1961 when US sent the first chimp into space, rocket technology had vastly improved. Live expectancy for space monkeys was very short in those early years. Monkeys where the first astronauts, with an initial flight in 1948 aboard a V-2 rocket. Research with primates in the US was partially linked to our space program. The traditional interest was also mainly in primates most closely related to us, especially chimpanzees and bonobos. This meant primates living on the ground rather than in trees: terrestrial monkeys and terrestrial apes. This is important because no single slice of time will do to allow a full understanding of primate behavior.Īnthropologists were traditionally interested in studying primates with adaptations most similar to our own. Research programs were established that have enabled data to be collected on specific troops of baboons, chimps and other primates across 40 years and growing. This means that field studies must occur across decades to provide true understanding. Baboons live for about 25 years on average and chimpanzees for about 50 years. She made some remarkable discoveries and helped to usher what might be termed primate ethnography, becoming embedded within a primate social group so as to witness behavior in a very up-close and personal way. ![]() This is when Jane Goodall began her long-term study of chimpanzees. Intensive field research of primates in wild settings began in the 1960s. He has spent some 30 years studying a troop of baboons in Africa and the role that stress plays in health outcomes. Robert Sapolsky is a world famous primatologist who is a professor of Neurology & Neurological Sciences at Stanford. Some primatologists are trained in anthropological departments as physical anthropologists, but some train in other disciplines such as biology. And one of the major goals in primatology is to help understand human evolution and human nature. Studying primates (primatology) is inherently interesting to some because of some obvious similarities of these animals to us. Primatologistsstudy the evolution, anatomy & behavior of nonhuman primates. The primate order contains all the species commonly related to the lemurs, monkeys, and apes, with humans included in the latter category. The Yeti and Bigfoot are not on the list they only exist in the minds of some people. There are some 260+ primate species in the world today all grouped together as members of this biological order. All living primates, including humans, evolved from earlier primates that are now extinct. Humans are the only primate capable of living in virtually any environment of the world, all because of culture, our learned behaviors. You’ve probably seen pictures of Japanese macaques, or snow monkeys, sitting in hot pools with their heads covered with frost or snow. A few species of monkeys (snub-nosed and macaques) have expanded into areas of cold and snow in Asia and Japan. Most primates live in the tropics and indeed this was the setting of their evolution, which began around 66 millions years ago at the Cretaceous–Tertiary boundary when dinosaurs went extinct. When, where, & why did early primates emerge?.What distinguishes humans from other primates?.How do primates differ from other mammals?.This chapter’s learning objectives include: ![]()
