Bigfoot Bigfoot has fascinated mankind for as long as the two races have been in contact with each other, as infrequent and fleeting as that many be. The reason for this has less to do with Bigfoot's size and man- ape like appearance, which would be understandable on this Earth, as with Bigfoot's elusiveness. Gorillas, for instance, are as large.
Chimpanzees seem as intelligent.
The answer lies in his seemingly uncanny ability to elude detection. Bigfoot is indeed an interim model of one of the six races of man. How did the others not retain this. During the evolution of man, during periodic genetic engineering efforts, the entire race would be affected. All within a given race were in breeding proximity of each other, and the genetic alterations spread out accordingly.
