The Future Is Wild (2002) Episode 4 Prairies of Amazonia Episode Title: Prairies of Amazonia Episode Description: This episode is set in South America where the Amazon Rainforest used to be, 5 million years in the future. It features three species: (1) Carakillers, a descendant of the mountain caracara which has evolved to replace land predators; (2) Babookari, a descendant of the uakari which lives like baboons and has discovered how to catch fish; (3) Rattleback, a descendant of the agouti which has developed tough armor and can live through quickly-passing grass fires. By this point in time, the Amazon rainforest has been replaced by grassland. The episode follows the various animals of the Amazon prairies, seeing the Babookari become smarter than their ancestors through the construction of tools and a prairie fire threatening to tear the local environment apart.
