More than anywhere, the Serengeti is synonymous with wilderness and has even come to represent Africa. But the story of the Serengeti is just as much about humans as it is about wildlife. Right from the origin of our species in Africa, humans have been profoundly shaping this unique wilderness - hunters and pastoralists with cattle and fire, ivory traders and big game hunters, conservationists, scientists, filmmakers and even tourists have all played a part in shaping the Serengeti. Probably most powerful of all was a tiny microbe unknowingly brought to Africa by a small Italian expeditionary force - Rinderpest, a deadly virus that swept through the continent decimating cattle and wildlife alike and forever changing the face of the wild. The Serengeti is far from timeless, it is forever changing - and wherever there is change, the influence of Homo sapiens is not far behind.
