Imagine no more, I do not believe culture - as described in the article - exists. When I talk about culture I talk about the arts and literature of a particular time period, area, language, and social status. If someone talks to me about German culture or even something as narrow as Danish culture I know they are discussing a stereotype or cartoon. Cartoons are of course often useful for rhetorical or humorous effect.

That said there is of another difference between the two concepts - race (as described by racists) is something that is considered to not be created by humans but something essential and unchangeable by the person; whereas culture is always something considered to be created by humans.

The arguments against race, as well as not clustering nicely and the within group-variation thing, all hinge on race being a social construct - like culture.

Perhaps the reason then that race and culture would be so similar is that they are in fact both very much alike in that they are concepts created by humans.
