I noticed this question:
It has 2 upvotes, and as far as I can see, no close votes (maybe I still don't have the reputation to view them though).
The link of the question to biology is extremely tenuous, if it exists at all. OK, so humans are a subject of biology. But this is about their cultural behavior, which is not predetermined by their biology.
Is this indeed seen as a biological question? If yes, do we really want questions about human behavior on the site? Where do we draw the line to politics, sociology, economics, etc.? Do we want to answer "why do humans play cards" or "why did rich women in the 20th century wear leopard furs"?
