I hate how fucking smug and confident

Never have I seen greater irony, you sanctimonious and ignorant cunt

My comment is clearly idle speculation from a non expert, and worded exactly that way.

(1) You are NOT an expert.
(2) You are dead fucking wrong

The definition of rare assumes a lot. We're talking about life or death here. It's a goddamn good assumption this thing isn't the best thing since sliced bread since I don't see anyone using it. Car accidents are rare or we would not drive them. I'm still wearing my seatbelt though.

Male Lions exist mainly to fight and protect the pride. They can fight to the death for access to mating. They will kill other male cubs when taking over a pride. They will usually die when scarred up and kicked out of a pride.

Most deaths of male european robins are from fighting one another.

My point is that animals do enter physical combat at times, that ignores physical injury for all of the reasons I indicated - when life and reproduction are threatened, then it is adaptive, you fucking CUNT.

But if you want to bicker about the word often, let me be clearer: there are species that always fight to the death. For example, in several species of ants, multiple queens can cooperate to found a colony. Once the colony is strong however, they kill each other because that fucking makes sense.
