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.

Exlains the four-fields of anthropology, defines the concept of hilsm, and describes how anthroplogists approach their subject matter form a holistic and comparative cross-cultural perspective in order to reach the braodest and most inclusive conclusions possible on their subject of interest. Each field, cultural, physical (biological), linguistic anthropology, and archaeology, are described and situational material is included to illustrate how each field functions and interconnects with the others. This video also introduces the student to the way anthropologists carry out their analyses through rigorous fieldwork and participant observation in order to create the ethnographies that describe human cross-culturally.

Humans are biological organisms that have a place in the natural world. To understand what it means to be human we need to understand how we became human. The video introduces the topic of biology by looking at an important evolutionary force, natural selection, and how it has affected a species of fox living on islands off of the California coast. Next, the ultimate source of variation is examined as the hereditary material, DNA, is examined. Genes, alleles, and proteins are discussed as part of normal human physiology and with their involvement with inherited genetic diseases. How the hereditary material is distributed to offspring is the focus of meiosis by which sex cells are formed. Crucial here is that there are different combinations that lead to variation between each sex cell. Mutations give rise to new variations on which natural selection can act upon. In the final segment of the video, population genetics is showcased. A human case of natural selection, sickle-cell trait, is highlighted. Non-Darwinian forces of evolution, gene flow and genetic drift, are explored and the video ends with a discussion of how the evolutionary forces can change a population.

This video succinctly presents a portrait of what it is to be a primate with adaptation to an arboreal environment. The suite of traits that distinguish primates are presented along with a comparison to other types of mammals. Then the video delves into the adaptations and traits that distinguish the various type of primates from one another. Prosimians, tarsiers, New World monkeys, Old World monkeys, and hominoids are all adroitly described and distinguished. The types of locomotor patterns, diets, and habitats used by primates are interwoven throughout.

This lesson tackles why we study the behavior of nonhuman primates and how their behavior patterns can be related to human behavior and evolution. Experts discuss their field study experiences and what they learned about the behavior of their subjects. Social structure and social organization are related to impact on reproductive success. The central mother-infant bond is explored, along with patterns of affiliative and aggressive behaviors in social groups. Nonhuman capacities for language and culture are also addressed in interesting ways

Experts at the cutting edge of paleoanthropological research show how it?s done. In this video, students are introduced to the ways researchers gather data in order to answer the basic human question: Who are we and where do we come from? The multidisciplinary approach to this research is shown through interviews with established paleoanthropologists and with researchers in related areas such as archaeology, geology, the reconstruction of paleoenvironments, geomorphology, paleontology, and paleobotany. There is a strong focus on Koobi Fora, one of the most important field sites in paleoanthropology. In the last segment, relative and chronometric dating methods are explained in ways that will demonstrate state-of-the-art methods for discerning how old a specimen is.

Who is related to whom? How do species evolve? What has happened in geological time? This video focuses on macroevolution and the processes that explain it. It begins on location at a paleontological site in the Big Horn Basin, Wyoming, where scientists are recording mammalian evolution in the first ten million years after the Cretaceous/Tertiary boundary extinction. A key question of macroevolution is, ?What distinguishes a species?? This leads to taxonomy and discussion of the two main approaches to classification: evolutionary systematics and cladistics. Examples are given of homologies and analogies, and ancestral and derived traits, keys to classifying by these different approaches. Cladistics focuses only on derived traits. In the second segment, two different species concepts are mentioned?the biological species concept, which is the most commonly used definition, and the ecological species concept, which places emphasis on niche occupation and natural selection.
