Subtitled “a natural history of the future”, this book (and presumably the accompanying 12 part TV series that the book accompanies) is a fascinating reverse of all those books looking backwards in time at evolution. Here the authors have beautifully speculated on how things will go in the future. The book is split into three broad sections. One, set 5 million years in the future finds a largely unchanged world in the grip of an ice age. Here the animals may be unfamiliar, but they are clearly derived from current forms. In the other two sections, looking 100 and 200 million years ahead, much bigger changes have occurred. Continental drift has resulted in a reshaping of the earth’s surface. Creatures are developing significantly, with some creatures leaving the sea (imagine a land-based giant squid), birds taking to the water, and descendents of fish flying. Highest in yuck factor is probably some of the insect life, while most striking are the envisaged developments from jellyfish,
