Lucy-(4 min 33 sec) Don Johanson describes finding the knee joint in Hadar, Ethiopia, that first indicated a bipedal hominid had lived 3 million years ago. His subsequent expedition led to the discovery of Lucy, a 40 percent complete skeleton of a new species of hominid, now known as Australopithecus afarensis. The final piece of the puzzle was a skull from the same site, which clearly demonstrated that Lucy's kind were small-brained, although they walked upright.
How a Fossil is Formed (3 min) using Lucy as an example, the process of fossil formation is illustrated Who Was Charles Darwin? (6 min) Discover how Darwin's uriosity, his passion for natural history, his voyage on the Beagle, and his use of the scientific process led to the publication of his groundbreaking book. Darwin-Reluctant Rebel (3 min 29 sec) James Moore explains that Darwin developed his theory of evolution by natural selection at a time when creationism dominated the public thinking. In this video segment, Darwin is seen arguing for his theory with creationist thinkers, including the HMS Beagle's Captain FitzRoy, his colleagues, and even with his own wife Emma. Philosopher Daniel Dennett explains that humans naturally want to believe that there is some purpose to the universe, and prefer to think of themselves as "special," rather than just another species in the animal kingdom. From Evolution: "Darwin's Dangerous Idea." Theory- (6 min 15 sec) When we use the word "theory" in everyday life, we usually mean an idea or a guess, but the word has a much different meaning in science. This video examines the vocabulary essential for understanding the nature of science and evolution and illustrates how evolution is a powerful, well-supported scientific explanation for the relatedness of all life. Did Humans Evolve? (5 min 34 sec) By exploring both fossil and molecular evidence for human evolution, this video from Evolution contrasts the ideas of relatives and descendents in order to illustrate our connection to other primates and define what is meant by a "common ancestor." It also discusses the similarities and differences in DNA sequences between different species. How Do We Know Evolution Happens? (7 min 4 sec)- Mammals evolved on land more than 200 million years ago. So how did the world's largest mammals -- whales -- end up back in the water? That's the question Dr. Philip Gingerich, a paleontologist at the University of Michigan, is trying to answer. Gingerich became intrigued when he found what looked like the fossil skull of an early wolf in Pakistan in 1978. But closer examination of this wolflike skull revealed it contained an ear structure resembling that of modern-day whales! This was the first fossil ever found that supported one of Darwin's most controversial ideas -- that whales had descended from land mammals. Facts about Human Evolution (12 min)-Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development of many hominin species, now all extinct. Hank will introduce us to these species & the breakthroughs responsible for their development, and help us understand the awesome ways in which they led to us. Vestigial Structures (4 min) Hank discusses many examples in humans What Darwin Never Knew (2 hours) NOVA on PBS Websites
