All it takes is one scientist to start examining the evidence. Jeff Meldrum has a Ph.D. in primate locomotion, and has examined the physical evidence, mostly footprint casts, which show evidence of a mid-tarsal break and fine dermal ridges, which is what gives us finger and toe prints. His book only examines physical evidence, and addresses those who think these things are hoaxes. Unfortunately this opens him up to ridicule, because, if these things are real, much of what we think we know about primate evolution on this planet goes out the window.

Bending stresses in the digits are held low by selection for relatively short toes that participate in propulsion at the sacrifice of prehension. Efficiency and economy of muscle action during distance walking and running are maximized by reduced mobility in the tarsal joints, a fixed longitudinal arch, elastic storage in the well developed calcaneal tendon, plantar aponeurosis and deep plantar ligaments of the foot.> In contrast, the Sasquatch appear to have adapted to bipedal locomotion by employing a compliant gait on a flat flexible foot. A degree of prehensile capability has been retained in the digits by maintaining the uncoupling of the propulsive function of the hindoot from the forefoot via the midtarsal break. Digits are spared the peak forces of toe-off due to the compliant gait with its extended period of double support. This would be a efficient strategy for negotiating the steep, broken terrain of the dense montane forests of the Pacific and Intermountain West, especially for a bipedal hominoid of considerable body mass, The dynamic signatures of this adaptive pattern of gait are generally evident in the footprints examined in this study. http://www.isu.edu/~meldd/fxnlmorph.html
