"What animals should we act like? Black widow spiders who pull the heads of their male companions when they're having sex with the female spider?"

That's another reason to not get upset about these sort of studies even when they are done by real scientists. Acceptable human behavior is a different issue than what animals do. For example my cat thinks nothing of lifting his leg and licking himself when we have company.

But it is interesting to see the behavior is naturally occurring in a wide variety of species - it may play into the nature versus nurture for animal behavior debate.

Animals "tag" territory they claim as their own. Signs and fences don't matter to them.

By animal kingdom rules, gangs of taggers should be permitted to do as nature compels them.
