a group of Norwegian barbarians. O shows them fire, which intrigues the group. They use their fur coats to light up the fire even more, but the fire melts the ice and their coats are lost in the bottom of the ocean. The group chases after O, but Croak flies in and saves him. As Croak flies O to safety, O is eaten by a shark. O eventually escapes from the shark and finally meets his human family. The elder recognizes O and instantly dies. O takes over as leader and tells them that he'll teach man what he has learned on his travels. While teaching them, Igua finally catches up with O. However, O is still angry at Igua. Meanwhile, Ah (O's brother, though neither of them know that they are related) takes over as leader and shoves O away into the fire that was made by Ah. Igua saves him, and both O and Igua reconcile their friendship. Ah (in caveman talk) tells his people that they must show the world who is boss. They set out reshaping the earth in their own image and destroy any creature standing in their way. As a result, the dragon disappears from the face of the earth, the No-Lobes are all exterminated in a war against Ah, the dinosaurs drive themselves to extinction by committing mass suicide, the feline clan is slaughtered and used for clothing and jewelry (save for No-Man, who later dumps O), and the ant colony attempts to escape via a rocket made of grass, which ends up crashing back down and killing them all, as well as causing Pangaea to split into the earth's continents. O, Croak and Igua escape the devastation and soon find a deserted island where they spend the rest of their lives, with O taking upon the title of the missing link and contemplating the severity of his actions. Cast Production Development Because of the remarkable success of the 1975 film, Tarzoon, la honte de la jungle, Picha was encouraged to address another subject, that of Darwin and his theory of evolution.
