Please discuss the role of menopause from an evolutionary perspective
Menarche marks the beginning of the reproductive life of women, whereas menopause marks its end. Menopause is the irreversible cessation of fertility that occurs in all women before the rest of the body shows other signs of advanced aging. Only humans have a significant part of the life span that extends beyond the female reproductive years. Menopause has occurred in human species as long as recorded history, and there is no reason to doubt that it has characterized older human females since the dawn of Homo sapiens. Although highly variable, menopause usually occurs around the age of 50 years. Kristen Hawkes proposes that menopause is the most prominent aspect of a unique human pattern of longevity and that this pattern has been shipped largely by the inclusive fitness benefits derived by postmenopausal grandmothers who contribute to the care of their grandchildren. Pecci argues that the post reproductive life span of women allows them to devote greater resources to the children they already have and that this factor alone could account for the evolution of menopause.

________ is a field devoted to the gleaning of all the information that can be extracted from fossils.
Paleontology
According to the authors of the text, why did the Neandertal have such large face and nose features?
The size of the Neandertal nose was explained as an adaptation too cold and in arid environments. The nasal form was subject to functional forces that affected other parts of the face. This was associated with the chewing functions of the face, rather than with the local climate.

Who were the Neandertals?
Scientists now believe the Neanderthals were our closest extinct human relatives, sharing approximately 99.7% of their DNA with modern humans. Although they are considered by many scientists to be their own separate species (Homo neanderthalensis), some scientists believe they could simply be a sub species of modern humans (Homo sapiens). The Neanderthals lived throughout Europe and Asia during the Pleistocene Epoch (often referred to as the Ice Age). Scientists estimate they died out approximately 30,000-40,000 years ago. No one knows for sure why the Neanderthals became extinct. Some believe drastic climate change could be the culprit. Others think modern humans killed the Neanderthals. A more recent theory holds that Neanderthals interbred with modern humans until they were eventually absorbed into our current species. Neanderthals looked quite a bit like modern humans, although they tended to be shorter and stockier. Scientists believe their bodies were specially adapted for cold weather, since they lived during the Ice Age. To survive in the ice and snow, many Neanderthals found shelter in the limestone caves found throughout Europe and Asia. They've often been referred to as "cave men," because many Neanderthal fossils have been found in caves. Neanderthals had large, complex brains similar to those of modern humans. They created and used tools, controlled fire, and buried their dead. Scientists believe they also lived in nuclear families and likely cared for sick and elderly family members who could not take care of themselves. Scientists aren't sure if they had a developed language, but they think it's a likely possibility given the size and complexity of their brains. They also made and wore clothes. Although they hunted large animals, they cooked and ate vegetables regularly. Most Neanderthals lived to about 30 years of age.
Which group of animals were the principal ones affected by the catastrophic environmental change that took place during the Mesozoic and why?
The Mesozoic or "middle life" era is often referred to as the "age of reptiles" because it was during this time that the reptiles, most notably the dinosaurs evolved into the dominant group of animals living on the planet. However, there was so much more to the Mesozoic than its famous reptilian killers. More importantly it was a time of the great innovation and diversity among life on Earth.
Which of the following statements is true regarding bipedal locomotion among hominids?

What is one of the most important differences between the social behavior of bonobos and chimps?
The biggest differences between the two are in how they govern their societies: Chimps are led by an alpha male and tend to maintain order through aggression, while bonobos are dominated by females and keep the peace through sex. Although the physical variations between chimps and bonobos are interesting, what's even more fascinating is their behavioral and social differences. Overall, bonobos have a "make love, not war" mentality, which is in stark contrast to the often aggressive and violent manner of chimps. For bonobos, sex is used for almost everything, including avoiding conflict, showing affection, reducing stress, solidifying social status, and simply saying "hello." Bonobos are much more likely to keep the peace by offering a sexual favor, whereas a chimpanzee's first instinct is to secure dominance through battle. In chimp groups, the highest-ranking male is the only one allowed to mate with the females, but in bonobo cultures, everyone has sexual freedom, and sex acts occur between all combinations of ages and genders.
Why is incest taboo universal among the human species?
The interest that anthropologists have shown in the Incest Taboo has been described as bordering on an obsession. It used to be believed that the Incest Taboo is a universal taboo. Some anthropologists have, however, successfully contested this view, pointing out that what appears universal to human societies is the avoidance of sexual relationships between very closely related individuals. It has been shown that in many cultures in which the Incest Taboo is not formally expressed, close relatives still seem to avoid sexual relationships, especially when such relatives have lived together most of their lives. Anthropologists have noted, also, that human societies tend to invest more effort in spelling out Incest Taboos with respect to what has been referred to as "fictive kin-ships." There is evidence to believe that mother-son incestuous paring had been part of the fertility magic ritual of prehistoric Paleolithic man, and that such incest was common enough to impact significantly in human evolution, especially with regard to juvenilizing of the human species. The circumstantial evidence for this conclusion is not only in the widespread myths of mother-son incestuous divine pair in early historic Mediterranean world, but also from a detailed examination of the heterosexual dualistic philosophy of fertility cults. It would appear that the intensity of inbreeding associated with incestuous cultic rites had played an important role in the stabilization of the human genetic pool.
