everything is biology. how we look. how we behave. how we think. how we feel. these characteristics are affected by our genomes (nature). they are also affected by the evironment (nurture, epigenetics).
humans are products of biology. we’re organisms existing in environments.
some people say that genes only code for proteins. yes, that’s true(-ish). but organisms are built of proteins, and those proteins (and the amounts and their arrangements) that you happen to be made of clearly must affect what you are like. therefore, genes affect what you are like (since they coded for the proteins).
human cultures are emergent properties of the characteristics of groups of humans. in other words, human cultures are also emergent properties of biology, since humans are biological organisms (are there any other kind?). however, there are also “accidental” aspects to cultures that are contingent upon the environments in which the groups exist as well as some goofy mechanisms like cultural exchange (which is really just an element of a group’s environment, isn’t it?).
note that there are feedback mechanisms in all directions here: genes affect human behavior may affect environment which may in turn affect genes again. or, genes affect human behavior affects culture may effect genes again.
