The Cradle of Evolution or The Origin of Species

A young man has been having the same dream for 2 months. It always ends with two familiar figures. He wants to know who they are. Meanwhile, Ash and his friends are at the Olduvai Gorge in Tanzania, Africa on a special trip. By chance, Mewtwo is also there. When Ash and Mewtwo look at the view in the gorge, they feel as though somebody walked over their graves. An adventure awaits.
