Why do human testicles hang like that?

[...] the first big question is why so many mammalian species evolved hanging scrotal testicles to begin with. The male gonads in some phylogenetic lineages went in completely different directions, evolutionary speaking. For example, modern elephants' testicles remain undescended and are deeply embedded in the body cavity (a trait referred to as "testicond"), whereas other mammals, such as seals, have descended testicles but are ascrotal, with the gonads simply being subcutaneous.
Gallup and his coauthors jog through several possible theories of our species' testicular evolution by descent.

monochrom is an art-technology-philosophy group having its seat in Vienna and Zeta Draconis. monochrom is an unpeculiar mixture of proto-aesthetic fringe work, pop attitude, subcultural science, context hacking and political activism. Our mission is conducted everywhere, but first and foremost in culture-archeological digs into the seats (and pockets) of ideology and entertainment. monochrom has existed in this (and almost every other) form since 1993.
