ANTHROPOLOGY EXAM 3 WVU WITH CERTIFIED SOLUTIONS what makes us human? Bipedalism, brains, skulls, Childhood dependency, tools, teeth biopedalism stresses the advantages it provided in a habitat increasingly dominated by dry, savanna-like conditions. Brains and skulls Early hominins had very small brains, Brain size has increased during hominin evolution, especially with the advent of the genus Homo. Childhood dependency Compared with the young of other primates, human children h...

Deductive Thinking - Answer - science proceeds by advancing hypotheses and comparing them to facts. - facts can be observed from nature, or we can construct experiments to test specific hypotheses Thinking Conceptually - Answer - logical interpretation and inference is simple, but not always easy - being on familiar grounds helps us think clearly Logical Equivalence - Answer - if they express the same fact in different words. In other words, if either one is true, the other one must be...
