"Male beetles use their horns to battle each other for supremacy, with the winner getting the opportunity to mate. "
And how do they know that?
The truth is that they have no clue why the beetles had horns, it's the researchers who have sex on the brain and everything has to have a sexual explanation. And this is reasearch?!
It is baffling to see why Bug Sex is so important to these Scientists...
There's a Viagra joke in there somewhere.Oldest Known Penis Is...Sex was first recognized in the fossil records more than 500 million years ago and the oldest known penis... belongs to an ostracod, an early crustacean related to crabs, shrimps and water fleas, and was found in a fossil sample unearthed in Brazil.

Beetles are modern - their mating behavior has been observed.
