Change in diet is important in a changing species over a time as long as
fifty million
years. The earliest creatures in theseque3nce leading to man were numble0-eyed and
delicate-fingered insect an fruit eaters like the lemurs. Early apes and hominids from
Aegypopithecus and Procosul to the heavy Australopithecus, are thought to have spent
their days rummaging mainly for vegetarian foods. But the light Australopithecus broke
the ancient primate habit of vegetarianism. The change from a vegetarian to an
omnivorous diet, once made, persisted in Homo erectus.
