PHL243H1 Chapter Notes -Anal Sex, Hunter-Gatherer, Libido
Document Summary
Homosexuality is abnormal because the penis is for vaginal intercourse, not anal intercourse with men. If we can identify a natural function of an organ, then we can say it is behave abnormally when it fails to perform this function or performs an action thwarting this function. Function doesn"t necessarily imply a conscious creator who created an organism with a specific purpose. A thing"s functions are its effects that explain its existence, ex. a clock"s function is to tell time, because that"s why the clock exists. X is normal if it adheres to why this trait over others was selected via evolution (ex. a dull shark"s tooth would be abnormal because shark"s teeth are meant to sharply bite things) Leading to reproduction got the sex drive selected in, so reproduction is its function. Genes are fit insofar as they produce copies of themselves and genes which programmed heterosexual intercourse were more likely to replicate than their competitors.
