尼安德特人在地球生存的时间长达九万多年，真正主宰着冰河时期的欧洲，比至今为止现代人生存的时间还要长。考古学家的各种发现都表明，尼安德特人有着强壮的体格、发达的智力、先进的工具，他们比我们想象中更像人类。那么，他们为什么从世界上销声匿迹了呢？是因为经不住恶劣自然环境的考验？还是因为与现代人祖先的交锋？又或是因为天灾？科学家持续研究着尼安德特人灭绝的原因，他们的遭遇可能也会发生在我们身上。　　制作：Story House Productions GmbH, C-Tales Entertainment, The History Channel, ZDF Enterprises

简介：【内容简介】n东非大裂谷自红海至赞比西河口，连绵三千里，从太空都能看到。这里是多姿多彩的地方，有喷发的火山、覆盖着森林的高山、美丽的峡谷、广袤的草原、巨大的平湖和河流，是鳄鱼、河马、狮子、大象、火烈鸟和非洲人的家园。BBC采用最新的高清摄影技术，探讨了形式东非大裂谷的地质力量，展现世界上野生动物品种最多的地貌。nVisible from space, Africa's Great Rift Valley runs three thousand miles from the Red Sea to the mouth of the Zambezi. It's a diverse terrain of erupting volcanoes, forest-clad mountains, spectacular valleys, rolling grasslands, huge lakes and mighty rivers, and is home to crocodiles, hippos, lions, elephants, flocks of flamingos and a diversity of indigenous peoples.nUsing state-of-the-art high definition filming techniques, this series investigates the geological forces which shaped East Africa's Great Rift, and which make it one of the world's most wildlife-rich landscapes.nPart 1: FirenThe valley is the product of deep-seated geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. Their peaks provide a refuge for East Africa's most extraordinary wildlife, including newly discovered and previously unfilmed species which have evolved surprising survival strategies to cope with their challenging mountain environment.nPart 2: WaternThe Great Rift Valley channels a huge diversity of waterways - rivers, lakes, waterfalls, caustic springs and coral seas - spanning from Egypt to Mozambique. Some lake and ocean deeps harbour previously unseen life-forms, while caustic waters challenge life to the extreme. But where volcanic minerals enrich the Great Rift's waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa.nPart 3: GrassnThe Great Rift Valley provides the stage for an epic battle between trees and grass - its course influenced by volcanic eruptions, landscape and rainfall. On its outcome rests the fate of Africa's great game herds. In the Rift's savannas, grazers and their predators struggle to outwit each other, forcing one group of primates to develop a social system that paved the way for the evolution of mankind.
