How Wide is the Congo River at Its Widest Point? What is the basic difference between relative and absolute dating? Bonobos overall act peacefully in the wild. In Europe and Africa tropical forests became woodlands and grasslands, while in Asia decreased rainfall resulted in reduced forests and decreased fruit availability. While looking at the teeth you notice a large space between canine and first premolar. Human babies have more elaborate culture to learn than ape babies.

The best accepted hypothesis for the dispersal of African monkeys to the New World is. Great Apes, containing the orang-utans, gorillas, chimpanzees and humans, a brain that is larger and more complex than other primates, distinctive molar teeth in the lower jaw which have a Y5 pattern (five cusps or raised bumps arranged in a Y-shape), a shoulder and arm structure that enables the arms to freely rotate around the shoulder, a ribcage that forms a wide but shallow chest, body size which is similar in males and females, bodies adapted for living in trees which they rarely leave. The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern. 2 - Name and briefly describe the three hypotheses of primate origins.

The only species in this genus, this hominin lived about 3 million years ago. Which fossil group is characterized by an eye orbit fully enclosed by bone? Reproduction places different energy demands on males and female, resulting in varying reproductive strategies. The index of refraction of the film is 1.4.
