This is almost as much of an art book as it is a book on evolution. The images, photos of about 30 paintings by Alexis Rockman, mostly oil and acrylic on wood or watercolor and ink on paper, are stunning depictions of creatures, past, present and to come: an arsinotherium (a rhino-like animal), a thylacine (a doglike marsupial, extinct in 1936), huge dandelions with thick roots several feet long, rabbits and rats on hind legs like kangaroo, crows like vultures, snakes with wings, etc. The text by geologist Peter Ward is sprightly, informed, very readable, and at times even moving, as when Ward recalls his return to New Caledonia after twenty-five years.
Ward's vision, however, is not pretty. He is not looking at planet earth after humans have gone extinct as some other books on future evolution have done. He sees us as surviving for another 500 million years so that the fauna and flora that do evolve will do so with humans as probably the most significant part of their environment. Consequently there will not be any large mammals, and the most numerous creatures will be small and "weedy." They will be mostly nocturnal animals that have learned to tolerate humans, rats and insects and "escapes" from our farms and genetic engineering labs.
Ward is very good at producing striking word portraits. One is the "brown mountain" he observed flying into Mexico City (the polluted air rising above the city), and another is his fanciful creatures of the future, the "Zeppeliniods," who have learned how to create hydrogen-filled air sacks so they can float in the air. In a particularly dystopian vision on pages 135-137, Ward's time traveler visits a garbage dump 10-million years in the future crawling with "cockroach-sized insects...[and] mammals, a few as large as cats but most rat-, mouse-, or even shrew-sized." These creatures have evolved adaptations for exploiting the garbage dump: "some with long tapered heads, others with thin ribbonlike tongues, others with blunt heads and large knoblike teeth, still other with huge batlike eyes." A pig-like creature with rats "like hairy lampreys with greedy sucking mouths" hanging from its sides appears. Overhead large crows "with brilliant plumage" dive bomb the traveler with knifelike barbs on their feet, driving him bleeding toward a tree where a hungry flock of these clever and hungry crows await. Ward also sees a great increase in the number of snakes, some with unusual adaptations to feed on the garbage eaters.
This "dyspeptic" vision, like some of the other visions in the book, is calculated to shock and revolt the reader, but just how likely is it to come to pass? On the one hand it would seem, not very, since we are already recycling away from garbage dumps in many places in the world. On the other hand, if we consider that we, as domesticated creatures ourselves, may be getting dumber, this scenario might seem more likely. (See page 105 where Ward references neurologist Terry Deacon as noting that "all domesticated animals appear to have undergone a loss of intelligence compared with their wild ancestors.") My feeling, however is, that should we by some wild happenstance still be around ten million years from now (average life span of a mammalian species is about two million years) I would expect us to have used our technology to better effect. More likely of course (and Ward addresses this possibility, but dismisses it) is that we will be replaced by the products of our technology long before then. Whether "they" will think it worthwhile to continue "living" is a very interesting question.
Clearly this is a popular book, almost a "coffee table" book, aimed at a popular readership, but that doesn't mean it's simplistic or dumbed down. True, Ward is biased toward a long-lived humanity which he thinks is likely the only intelligent creature in the cosmos (see Rare Earth: Why Complex Life Is Uncommon in the Universe (2000), which he wrote with Donald Brownlee), but Rockman's paintings really are first rate, and although the speculations are no more than that, they are interesting in themselves. Additionally there is a wealth of information in the text about evolution. Ward points out for example that it is not likely that we are going to undergo much Darwinian-type evolution in the future unless some humans become isolated. This can happen, he speculates, if an elite population isolates itself reproductively from the masses, or if we establish far-flung colonies in space. Another nice tidbit is Ward's observation that the average human I.Q. is not going to change much because whatever is measured on I.Q. tests is subject to the actions of numerous genes and any short term anomalies will be flooded by the mass of genetic humanity.
This book is a bit pricey because it is printed on expensive, glossy paper for the reproduction of the paintings. It's an attractive and entertaining book.
