Man has been able to spread across the earth so widely for four main reasons. First, he is a terrestrial animal, not restricted to the forest. Secondly, he can cross any natural barriers, such as deserts, oceans and mountains. Moreover, he can live off a very wide variety of food. Most important of all, he has developed culture; he has learned to make clothes and build fires which allow him to live in climates where he would otherwise perish. To a large extent, he shares some of these advantages with the monkeys. They, too, can move over unforested land. They, too, can cross some natural barriers, as they have the ability to swim. And they, too, can digest many kinds of food. Thus, a single species of baboon has spread across Africa from Dakar in the west to Ethiopia in the east, and south all the way to the Cape of Good Hope.. Similarly, Macaques have done at least as well. One species, the rhesus macaque, is equally at home in forest, in open cultivated fields, and inside heavily populated cities.
