That's right people... this is an article investigating the evolutionary significance of fellatio (if you don't know what it is, look it up). Their results: what probably every male in the known universe could tell you, it happens because it feels good and there's real reward in that kind of pleasure.
But, looking past the seemingly obvious results, what I find astonishing about this paper is:
- someone thought to do this (as if they thought the reasons for other species would be different from that of a human - you and me baby ain't nothin' but mammals) and
- someone paid for this (it was paid for by a government entity: the Ministry of Science and Higher Education of Poland. Just another example of why a really good grant writer should be a key element of every research team.)
