After Man: A Zoology of the Future (1981) is a 1981 speculative evolution book by the Scottish geologist and author, Dougal Dixon. In it, he presents his hypothesis of various organisms apparent after a mass extinction succeeding our own time.

Geography of the futureEdit

In this new period of the Cenozoic, called the Posthomic, Dixon assumes that Europe and Africa would fuse, closing the Mediterranean Sea; whereas Asia and North America would collide and close the Bering Strait; South America would split from Central America; Australia would collide with Southern Asia (colliding with the mainland sometime in the last 10 million years), uplifting a mountain range beyond the mountains of the Far East that becomes the most extensive and the highest chain in the world, greater even than the Himalayas at their zenith 50 million years ago; and parts of eastern Africa would split off to form a new island called Lemuria. Other volcanic islands have been added, such as the Pacaus archipelago and Batavia.

Major groups of After Man: A Zoology of the FutureEdit

Some of the larger groups in the future include:


Rabbucks fill the ecological niches of deer, zebras, giraffes and antelope; but they are descended, as the name suggests, from rabbits. They live in almost any environment, and feed on grass. Their anatomy resembles that of ungulates. Gigantelope


The gigantelope take the niche held by elephants, giraffes, moose, musk oxen, rhinoceroses, and other large herbivores. They are descended from antelopes, and range in a wide variety of forms. One subbranch have evolved into the large, moose-like herbivores of the north (called the "hornheads").

Predator rats

The major group of terrestrial predators, who fill almost every carnivorous niche. They evolved, as the name suggests, from rats, and range in forms resembling polar bears, wolves, wolverines, cats, and even aquatic walrus-like forms.
