Professor Richard Fortey journeys high in the Rocky Mountains to explore a 520-million-year-old fossilised seabed containing bizarre and experimental lifeforms that have revolutionised our understanding about the beginnings of complex life. Among the amazing finds he uncovers are marine creatures with five eyes and a proboscis; filter-feeders shaped like tulips; worm-like scavengers covered in spikes but with no identifiable head or anus; and a metre-long predator resembling a giant shrimp.

In the misty and lush tropical forest surrounding South Africa's Soutpansberg Mountains, a 600-year-old outeniqua yellowwood tree reigns supreme. It's 115 feet tall, and a source of food and shelter for an array of plants and animals. Crowned eagles construct massive nests in her fold, and Samango monkeys take refuge in her branches. As if it wasn't unique enough, this ancient, endangered tree has no flowers, instead reproducing through male and female cones-a marvel of the natural world, and a true South African treasure.

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.
