Recent research by anthropologists shows that we had an arboreal past. Our genetic ancestors were once tree dwellers. At that time, our genetic ancestors depended upon products of the tree, and later upon the fruits of stalk and vine for our sustenance. Dr. Alan Walker, an anthropologist of John Hopkins University in Maryland, has done research showing that early humans were once exclusively fruit eaters. By careful examination of fossil teeth and fossilized human remains with electron microscopes and other sophisticated tools, Dr. Walker and his colleagues are absolutely certain that early humans until relatively recently, were total fruitarians. These findings were reported in depth in the May 15, 1979 issue of the New York Times.
Dr Alan Walker and his associates, anthropologists at John Hopkins University,using the most modern electronic microscopic equipment,state:
“Preliminary studies of fossil teeth have led to the startling suggestion that our early human ancestors (Australopithecus) were not predominantly meat-eaters or even eaters of seeds, shoots, leaves or grasses,nor were they omnivorous. Instead they appear to have subsisted chiefly on a diet of fruit. Every tooth examined from the hominids of the 12 million year period leading up to Homo Erectus appeared to be that of a fruit-eater.”

The essence of Walker’s research is that even though humans have adopted omnivorous and carnivorous eating practices, our anatomy and physiology have not changed. We remain biologically a species of fruit eaters. The human digestive system has been adapted to a diet of fruits and vegetables for more than 60 million years of development. A few thousand years of aberrant eating will not change our dietary requirements for optimum health. The position that humans occupy in the animal kingdom is that of the Primate order, which means that, from the point of view of anthropology, our closest animal relatives are the anthropoid apes (anthropoid means “resembling man” or “man-like”). This species includes gorillas, monkeys and chimps all of whom are classified as frugivores. From the perspective of physiology, our human biology and digestion most closely resemble our closest cousin in the animal kingdom, the orangutan. Even our DNA genetic material is well over 95% identical. Humans developed on fruits just as simians and other primates in nature. In consequence, some anthropologists and biologists have classified humans as frugivores.
