Humans are ashamed of certain activities that are critical to our survival. Examples: mating, defecation, exposing certain parts of our bodies

This restricts some activities from being performed while others are around (usually only if others are also humans).

Perhaps it is because we are the only species who is capable of feeling ashamed?

What are the advantages of this mechanism in terms of survival as a species?

    $\begingroup$ Welcome to SE Biology. In my opinion this is not the kind of practical biological question that can be answered in an objective manner, but is one the answers to which will be opinions and lie in the area of psychology or sociology. That is why I have voted to close it. $\endgroup$

  • $\begingroup$ I think there is certainly an interesting biological question underlying the evolution of e.g. fecal avoidance, which has been studied in a variety of organisms (e.g. pubmed.ncbi.nlm.nih.gov/24027342). Unfortunately, when such questions are applied to humans, they often end up descending into telling just-so stories about human evolution. $\endgroup$

  • $\begingroup$ Some humans are, not all humans, nudity for instance is definitely cultural. Don't confuse your cultures behavior with universal human behavior. $\endgroup$

    $\begingroup$ @RodrigodeAzevedo cultural behaviors generally have no genetic component they are purely learned behaviors. This is easily seen by the behaviors of people raised in drastically different cultures than their ancestry. Humans in general have so little genetic variation claiming anything cultural has a genetic component would require a great deal of evidence. $\endgroup$
