This lesson details the technological, artistic, and geographic expansion of the Cro-Magnons, the anatomically modern humans of Europe during the Upper Paleolithic era. The video details some of the major innovations, such as blade technique in which long, parallel-sided flakes are struck off the edges of a specially prepared core. It also details artistic endeavors of the Upper Paleolithic, beyond cave paintings, such as Venus figures. The geographic expansion during this time is also presented, highlighting the need for and development of a new technology used for their migration over open water. The video also illustrates the cognitive capacity of the Homo sapiens of the Upper Paleolithic, and how it allowed them to create technology that eased their daily survival.

This lesson explores how the accelerated rate of cultural change continued to drive human innovation in ways that transformed daily life for everyone. It illustrates the most radical cultural shift in the history of humankind that occurred in the Neolithic period (or New Stone Age), detailing the domestication of plants and animals and the shift to setting up permanent residences. The video concentrates on the Mayan civilization to explain the cultural changes that mark the differences between village life and urban settlements.

The video begins with comments on some instances of ethnic genocide that have occurred in the past in the Sudan, Rwanda, Bosnia, and Nazi Germany during World War II, and relates these occurrences to the concept of ?race,? a concept that is based on physical differences between groups. Briefly explains the historical context of how the concept of race emerged among European explorers during the sixteenth century. And, it explains that today anthropologists and scholars look beyond visible physical differences to explain human variation, that they analyze genetics and DNA, the cornerstone of genetic studies, to describe and understand human diversity. The video defines polymorphisms and clearly explains how their presence in human genotypes causes differences in phenotypic variation.

How do humans adapt to environmental challenges? In this video, experts explore this question from many angles. The difference between acclimatization and adaptation is explained. Nina Jablonski explains skin color function and adaptations related to UV radiation levels, the vitamin D hypothesis, and preventing the loss of folate in the body. High-altitude adaptations are also discussed, along with responses to heat and cold stressors. In the last segment, the evolutionary dance between humans and their pathogens is brought to light. The interwoven interactions between human cultural activities, and the evolution of new pathogens, as well as the evolution of drug resistance in existing pathogens are discussed.

The state of Oaxaca, Mexico, is the backdrop of this film, which explores the nature of culture and how cultures are studied. The Oaxacan society is used to illustrate the basic characteristics of culture: an integrated, dynamic system of beliefs, values, and behaviors that are shared by the members of a society; wholly learned and based on symbolic systems; and constituting humankind?s most important method of adaptation. Jayne Howell?s work in Oaxaca aims to determine how this society in transition is adapting to the pressures imposed by outside forces, and illustrates some of the methods of research that ethnographers employ in a biocultural approach to discovering how the world?s diverse cultures function.

This program focuses on the efforts of the Serrano tribe of Native American to revitalize their dying cultural traditions and language. The features and structures of human language in general are discussed, showing some examples from the Serrano language, and the role played by descriptive linguist assisting them is examined. A discussion of deaf sign languages reveals that they are in every way like all other human languages except that they are based on gestures instead of sounds. Nonverbal human communication systems are explored, as are various aspects of the fields of ethnolinguistics and sociolinguistics. African-American Vernacular English is discussed as an example of a social dialect that marks membership in a group. The film closes with a focus on the Serrano children, who it is hoped will carry on the tribal language and traditions.

When studying how personality develops, we cannot ignore the role that sex and gender may play nor can we overlook the biological factors that may influence and differentiate male and female behaviors. Determining whether gender roles influence personality and social identity or vice versa may be difficult, but we know that gender roles vary greatly from culture to culture. It is also recognized that every culture has individuals who are transgenders?people who do not fall neatly within the proscribed male and female categories. Western cultures prefer to think exclusively in male and female gender roles, but many other cultures have created a ?third gender? or even a ?fourth gender? in which to place these individuals. As individuals, we not only need to know who we are but also how we fit in and belong to the culture we were born into. Sometimes it gets complicated.

This film focuses on three types of subsistence patterns: foraging, horticultural/ agricultural, and pastoralism. What all subsistence systems have in common is the need for water. Who controls the water is at the heart of human survival. In the postindustrial era, traditional subsistence activities have been relegated to hobbies, such as hunting, fishing, and berry picking. The next time you ask ?What?s for dinner?? think about what it took to get food to your table.

The key trait that makes a hominoid a hominin is evidence for bipedalism. In this video experts discuss the physical changes that must occur for the transition to bipedalism including the more forward positioning of the foramen magnum, the large hole through which the spinal cord passes into the skull, a pelvis that becomes more bowl-shaped rather than the long blade-like pelvis of a chimpanzee, a longer leg, and a foot with springy arches. Important discoveries are examined in the time period from four to one million years ago including East African discoveries such as Australopithecus anamensis and the famous ?Lucy? specimen. The history of discovery in South Africa is reviewed starting with the first Australopithecus, the Taung child, and the more rugged genus Paranthropus. Finally, you will learn about the first member of our genus, Homo habilis.

About 1.8 million years ago, a new species of Homo appears in East Africa, a species that will exist longer than any other hominin. This lesson focuses on that new species: Homo erectus, the first hominin to leave Africa. In this lesson, you will follow the migrations of this species. You will explore the history of what paleoanthropologists have discovered concerning this widespread hominin in Java and in China and learn how the recent discoveries in the Republic of Georgia have turned much of what we knew about Homo erectus on its head. Finally, you will learn about a new type of tool industry that lasts for more than a million years.
