Activity 7 evolution of human
EVOLUTION OF HUMAN BEINGS Apes are the closest kin to humans in size, form, physiology and behavior. They have bigger brains, and brachian style of locomotion which is related to the evolution of an erect body posture and elongation of arms. Besides humans, gibbons, orangutans, chimpanzees and gorilla are the only living forms of hominoids. Gibbons and orangutans are arboreal brachiators. Orangutan, chimpanzee and gorillas, when on ground walk on all fours, supporting their weight on their fists(knuckle walkers). Chimpanzees and gorillas are more intelligent, can use simple tools and have the ability to learn sign language. Studies of DNA sequences have shown that humans are more closely related to chimpanzees than to any other primates. Human and chimpanzee’s DNA are 99percent identical, that is not to say that the humans have descended from fossil chimps. A common fallacy about evolution is that humans evolved from some living species of ape share a common ancestor. This ...
