The prestigious New York Times newspaper, in its May 15, 1979 issue, surprised me more by printing an article than the surprise they express by the findings revealed. The gist of this article concerns work done by an anthropologist, Dr. Alan Walker of John Hopkins University in Maryland. Dr. Walker has come to the startling conclusion that early humans were fruit eaters - eaters of nothing but fruit. This comes as quite a bombshell from a noted publication that has a vested interests in heavy meat-eating society.
By careful examination of fossil teeth as fossilized remains of humans with the aid of electron microscopes and other sophisticated tools, Dr. Walker and other researches are absolutely certain that our ancestors, up to a point in relatively recent history, were fruitarians. A cursory study of biology will reveal that we are indeed frugivores, even if written by meat-eating professors, which most of our biologists are.
