Operation Okavango could not leave southern Africa without stopping in Madagascar, the fourth island in the world. Its isolation has encouraged the development of unique flora and fauna. 200 million years ago, the earth was home to only 2 continents: Laurasia in the north and Godwana in the south. Under the effect of tectonic forces, they broke up into several plates which drifted away, taking with them entire sections of prehistory. This is how Madagascar, become an orphan island of Africa, escaped forever into the Indian Ocean with its cohort of bizarre animals that would become so many lemurs, chameleons or elephant birds. The Okavango expedition will cross these very particular southern worlds, from which Africa seems strangely absent.
