and Fessler; both examined the role of evolution in a human context and how natural selection aided in the adaptation of beneficial traits (disgust in this case) as a defense mechanism to prevent bodily harm to oneself and to possible offspring. These two studies, however, are limited because they are largely based on assumptions since it is impossible to know how early humans behaved. Extrapolating further, evolution based theories are merely theories based on these assumptions, therefore unreliable and unable to facilitate concrete conclusions. Evolution, however, provides one evidence-based claim and is vital to broadening the understanding of biological
