- S. 1 ÉP. 9 - How Big Was Homo erectus?20 mars 202432 minUsing 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 10 - The Movius Line20 mars 202432 minProfessor 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 11 - The Hobbits of Flores20 mars 202433 minThe 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 12 - Archaeology and Cooperation20 mars 202432 minExplore 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 13 - Presapiens or Preneandertal?20 mars 202432 minWorking 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 14 - What Do Stone Tools Reveal about Early Man?20 mars 202432 minFrench 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 15 - Did Neandertals Speak?20 mars 202431 minHow 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.Démarrer un essai gratuit de The Great Courses Signature Collection ou acheter
- S. 1 ÉP. 16 - Neandertals—Extinct or Ancestors?20 mars 202432 minFollow 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.
