I love this book. This is a journey to an Earth fifty million years in the future, when humanity is long gone and other creatures have been left free to evolve to adapt to natural conditions in the same way their remote ancestors did before we came on the scene.
Dougal Dixon presents a magnificent panorama of a world which, formerly shaped by humanity, has, with our exit on the universal stage, worked its remaining life into a vast, complex biota. Fifty million years from now the continents have continued their long march across the globe, and while the continents we know now are more or less recognizable in that far future time, they are distorted, some of them having slammed together to eliminate seas (the Mediterranean Sea is gone for just that reason), others beginning to rift into smaller sections (Africa has a new, giant island off her eastern shores, and the bulk of southern Africa is a good deal slimmer than in our day, thanks to that process), while new island groups have appeared in the world's oceans. And with these changes new groups of animals have evolved, some of them like nothing we know now.
Two groups of mammals, the rabbits and the rodents, survived humanity and became seedstock for the evolutionary process. Now, fifty million years later, deer- and antelope-like animals, descendants of rabbits, haunt the plains of the temperate woodland regions, while large, powerful carnivores such as the falanx and ravere, descendants of the rats that once swarmed our cities, prey upon the descendants of the rabbits and other large game. These "new rats" now fill the niches once occupied by now-extinct ferrets, stoats, weasels, wolverines, and other mustelids.
In the undergrowth of the temperature woodlands are such creatures as the tusked mole; the testadon, a strange descendant of the hedgehog; and the oakleaf toad, who sports on its back an outgrowth that looks very like an oakleaf, giving the little toad protective camouflage. The odd descendants of squirrels, geese, shrews, mice, and the like round out the faunal suite dwelling in the world's temperate regions.
Wetlands areas are home to creatures such as the long-necked reedstilt, whose striped fur makes it nearly invisible among the reeds of its swampy habitat. Dining on fish, it darts its head down into the water to catch its swift-moving prey; with fifteen cervical vertebra -- most mammals only have seven -- its neck is more than long enough for the task. This animal's teeth take the ancient primitive reptilian form, all the same length and shape, sharply pointed for the task of catching fish.
The world's coniferous forests are home to large herbivores whose ancestors in our world were antelopes. They sport a wide variety of horny headware that serve as sexual and species recognition signals, weapons, and food-getting tools. Other animals in the conifer forests include large-toothed borers who gnaw their way deep into the trunks of trees and nest there, numerous birds many of which have gorgeous plumage, weasel-like carnivores that prey on smaller animals, and the spine-tailed squirrel with its dark body and black-and-white striped tail, the latter bearing a tremendous number of sharp, stiff spines that the squirrel uses the way porcupines of our time did their spiky tails.
And so it goes through all the major divisions of habitats and niches on that world of fifty million years hence. After we were gone, those creatures that survived us radiated into countless new taxa which then filled niches emptied out because of our impact on the Earth. Tundra and polar regions, deserts, tropical grasslands, tropical forests, islands and island continents, and the oceans, lakes, and rivers all exhibit magnificent biotae, rich and diverse beyond anything we know today. The detailed, beautifully illustrated catalog of Earth's life fifty million years from now is followed by a section on the evolution of the distribution of Earth's land-masses, the process of evolution and the destiny of Earthly life, a detailed glossary, an index, and acknowledgements. The catalog is preceded by introductions by Desmon Morris and the author; evolution; the history of life; an overview of life after man.
With its gorgeous illustrations, this book is equally fit for the coffee-table and the scientific section of your library. Writing with dry wit and profound humor, Dougal Dixon is perhaps the finest writer of speculative biology today.
