Legends of ape-men have permeated human history for millenia, culminating in well-funded quests for the Himalayan yeti or abominable snowman in the 1950s as well as the Bigfoot craze that swept America through the 1960's and early '70's. But is there any credible scientific evidence for the existence of an undiscovered primate species? And could such creatures have eluded discovery for so long without having supernatural abilities? This book examines the evidence arguing for and against the existence of ape-men from the perspectives of investigators, witnesses, scientists, skeptics, and true believers, leaving you to decide whether we share the planet with mysterious simians or simply wish we did.
