Mystery of the Ice Age Giants

When the Ice Age ended 12,000 years ago, it also marked the end for many species of large mammals across the globe, such as mammoths, cave bears, and giant sloths. The common theory has been that climate change wiped out most of these animals, but recent discoveries are pointing to another culprit: our distant ancestors. Follow paleontologist Dick Mol and his colleagues on their hunt for clues to the extinction of the Ice Age giants, and to determine whether they were truly the victims of the environment, or of humankind.
