Also refers to the results natural selection: the evolutionary mechanism by which individuals with characteristics best suited to a particular environment to survive and reproduce with greater frequency than those without them. The strong will survive anthropologists have worked out a list of characteristics common to both ancient and modern primates: 2. relatively unspecialized teeth (incisors for gripping and cutting, canines for tearing and shredding molars for grinding and chewing) the senses. Smell declined, sight developed (brain size increased in the visual area), touch and grip developed: a great increase in brain size. The area of conscious thought (cerebral hemispheres) increased dramatically, the cortex enlarged the best evidence of our ancestry is with a group of apelike animals living in.
