Fortey travels to the rainforests of Madagascar - an ancient island that has spawned some of the most extraordinary groups of plants and animals anywhere in the world. From beautiful Indri lemurs, toxic frogs, and the cat-like giant mongoose called the fossa, to evolutionary oddities like the giraffe-necked weevil and the otherworldly aye-aye, he uncovers the secrets of the evolutionary niche - examining how, given millions of years, animals and plants can adapt to fill almost any opportunity they find.

The penultimate instalment investigates the primates, whose defining characteristics are forward-facing eyes for judging distance, and gripping hands with which to grasp branches, manipulate food and groom one another. The programme begins in Madagascar, home to the lemurs, of which there are some 20 different types. Two examples are the sifaka, which is a specialised jumper, and the indri, which has a well-developed voice. Away from Madagascar, the only lemur relatives to have survived are nocturnal, such as the bushbaby, the potto and the loris. The others were supplanted by the monkeys and a primitive species that still exists is the smallest, the marmoset. However, Attenborough selects the squirrel monkey as being typical of the group. Howler monkeys demonstrate why they are so named their chorus is said to the loudest of any mammal and their prehensile tails illustrate their agility.

Meet slime molds: the brainless blobs that can learn, make decisions, and navigate mazes. Who says you need brains to be smart? Extremely primitive life-forms called slime molds can navigate mazes, choose between foods, and create efficient networks—no brain required. New research on these organisms, which are neither plant nor animal, could help reveal the fundamental rules underlying all decision making.
