Anthropologist John D. Hawks wrote that it is fair to categorize the AAH as pseudoscience because of the social factors that inform it, particularly the personality-led nature of the hypothesis and the unscientific approach of its adherents.[34] Physical anthropologist Eugenie Scott has described the aquatic ape hypothesis as an instance of "crank anthropology" akin to other pseudoscientific ideas in anthropology such as alien-human interbreeding and Bigfoot.[35]
