Evolution and Prehistory: The Human Challenge
Format: PDF / Kindle (mobi) / ePub
Offering compelling photos, engaging examples, and select studies by anthropologists in a variety of locations around the globe, Haviland, Walrath, Prins and McBride present evolution and prehistory in vivid, accessible terms, and demonstrate how the field is relevant to understanding the complex world around you. You'll have the opportunity to explore the different ways humans face the challenge of existence; learn about the connection between biology and culture in the course of human evolutionary history as well as in shaping contemporary human biology, beliefs, and behavior; and see the impact of globalization on the continued survival of our species and planet.

thousands of painted caves, and two colossal statues of Buddha, carved into the cliffs at the valley’s edge and dating back some 1,500 years. In March 2001, the Taliban destroyed these two Buddhas on the grounds that they were idolatrous and an insult to Islam. Today, the niches that once held these grand sculptures are hauntingly empty. A huge international outcry has led to cooperative efforts to rebuild and preserve this archaeological site, and already the results have been impressive. In
Sexual reproduction increases genetic diversity, which in turn has contributed to a multitude of adaptations among sexually reproducing species such as humans. When new individuals are produced through sexual reproduction, the process involves the merging of two cells, one from each parent. If two regular body cells, each containing twenty-three pairs of chromosomes, were to merge, the result would be a new individual with forty-six pairs of chromosomes; such an individual surely could not
and benefits as a biological anthropologist, I wonder if primatological field studies on endangered great apes for the sake of Primates as Mammals Biologists classify humans within the primate order, a subgroup of the class Mammalia. The other primates include lemurs, lorises, tarsiers, monkeys, and apes. Humans—together with chimpanzees, bonobos, gorillas, orangutans, gibbons, and siamangs—form the hominoids, colloquially known as apes, a superfamily within the primate order. Biologically
stages of primate evolution, one incisor and one premolar were lost on each side of each jaw, resulting in a dental pattern of 2-1-4-3 in the early fossil primates. This change differentiated primates from other mammals. Over the millennia, as the first and second premolars became smaller and eventually disappeared altogether, the third and fourth premolars grew larger and added a second pointed projection, or cusp, thus becoming “bicuspid.” In humans, all eight premolars are bicuspid, but in
that is useful in observational studies—in rubbing. This sexual contact, typical and mouth-to-mouth kiss. Primate Social Organization our case, the stipulation that the reunion happen not long after the conflict. There is no intrinsic reason that a reconciliation could not occur after hours or days, or, in the case of humans, generations. Let me describe two interesting elaborations on the mechanism of reconciliation. One is mediation. Chimpanzees are the only animals to use mediators in
