镇馆之宝

　　第一季的《远古外星人》带领我们一起探索了数千年前智慧生命莅临地球的问题，提出了人类历史进程是否受到外星人的影响等问题。在第一季中，我们欣赏了远古洞穴壁画中奇异的生物，看到了秘鲁的飞机跑道遗迹，领略了印第安文字中所描述的“神的飞行器”这些反常的考古文物。
　　如果地球上的生命起源于外星球，远古外星人到访过地球，他们留下了哪些遗产，又留下了哪些线索，以证明他们曾在此驻足停留？ 远古外星人他们是谁，又怀揣着什么目的而来？
　　Daniken制作，History Channel电视台发行的《远古外星人》开始了第二季全新的探险，继续带着各位剧迷寻找并评估外星人降临地球的证据。从亚洲到非洲，从欧洲再到南美洲，让我们一起见证历史吧。

　　Visible 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.
　　Using 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.
　　Part 1: Fire
　　The 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.
　　Part 2: Water
　　The 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.
　　Part 3: Grass
　　The 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.
