Beehives, not so much. What bees construct are not found nature.
Yeah, so we agree on the end point, but the reasoning? No so much.
Because, try this: you say reproduction is a perfectly natural act. For bees, the beehive is a required part of that perfectly natural act. Bees cannot reproduce without the hive.
So, either bee reproduction is not really natural, or the hive is. Take your pick.
