- シーズン1エピソード8 - Who Was Homo habilis?2024年3月20日33分Examine what the fossil record reveals about Homo habilis, a species that serves as a transitional marker between Australopithecines and the rest of the genus Homo. A key mystery in this lecture: how Homo habilis can have the anatomy to be our ancestor yet not exist at the right time in evolutionary history.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード9 - How Big Was Homo erectus?2024年3月20日32分Using a magnificent find of the skeleton of a 1.5-million-year-old boy (known as the Nariokotome skeleton), delve into the issue of how important size was to becoming human. Recent discoveries of Homo erectus remains, as you’ll discover, have led to a reevaluation of the growth process of these hunters and gatherers.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード10 - The Movius Line2024年3月20日32分Professor Hawks explains the complexities of the Movius Line, a fairly clear line that separates the Western distribution of hand axes from areas in the East where they were rarely made. Central to this constant puzzler in the story of evolution are the more than 500,000-year-old remains of the Peking Man.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード11 - The Hobbits of Flores2024年3月20日33分The identity of Homo floresiensis, a species of small-brained humans that averaged a height of 3.5 feet, is the most burning debate in paleoanthropology. Investigate the origins of these mysterious “hobbits” and whether they represented a new species of human or were merely the remains of abnormally developed modern humans.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード12 - Archaeology and Cooperation2024年3月20日32分Explore what archaeology tells us about cooperation and compassion in prehistoric people with this insightful lecture. Professor Hawks reveals how archaeological remains and other kinds of evidence offer intriguing clues about how prehistoric people worked together to make tools, hunt animals, share meals, and even take care of their injured.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード13 - Presapiens or Preneandertal?2024年3月20日32分Working with the European fossil record, examine the debate over whether Neandertals were our true ancestors, or simply a much less specialized population. Along the way, you’ll comb through remains from Spanish caves in Atapuerca and encounter the notorious evolutionary forgery known as the Piltdown Man.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード14 - What Do Stone Tools Reveal about Early Man?2024年3月20日32分French archaeologist Francois Bordes interpreted variations in stone tool remains as evidence of different groups of people who existed in the past. American archaeologist Lewis Binford, however, believed these variations reflected different activities. Who was right? Find out in this lecture on the way scientists interpret the archaeological record.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード15 - Did Neandertals Speak?2024年3月20日31分How important was language to shaping human evolution? Discover the answer to this question by studying the skeletal remains of Neandertals discovered in the late 20th century. Learn how anthropologists, with the help of a specific bone and a key language gene, determined that Neandertals could—contrary to earlier beliefs—talk.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード16 - Neandertals—Extinct or Ancestors?2024年3月20日32分Follow along as scientists examine Neandertal genes to determine just how close our ties are to this primitive species, which disappeared about 30,000 years ago. What scientists found when the entire genome sequence of Neandertals was reconstructed in 2010—and what it reveals about the true fate of Neandertals—may surprise you.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード17 - Is Our Neandertal Heritage Important?2024年3月20日33分Are there behaviors we can trace back to our Neandertal heritage by closely studying mitochondrial DNA? If so, what’s useful? What isn’t? It’s a debate nearly as old as anthropology itself—and Professor Hawks’s explanation of how it works forms the subject of this provocative and insightful lecture.The Great Courses Signature Collectionの無料体験または購入
- シーズン1エピソード18 - Multiregional Evolution versus Out of Africa2024年3月20日32分Did modern humans emerge from Africa? Or did they evolve in regions around the world?
