An investigation, carried on over the past several years among various peoples of the Caucasus, has made possible the assembly of a file containing more than 500 statements by witnesses, who claim to have observed hominoid creatures personally, sometimes for lengthy periods of time. These hominoids are described as bipedal, covered with hair, and having no language. They are described in the local languages as “men of the woods” or “wildmen.” An analysis of the description of the “wildmen” discloses very precise anatomical, ecological and ethological criteria.This evidence, as well as certain observations collected in the field, indicate that these reported observations are real and are well founded in fact.
