Isn't it great to have a double penis?

Meanwhile, at the 2013 herpetology meeting, Gunther Köhler of the Senckenberg Museum in Frankfurt, reveals that sister species in the lizard genus Anolis often have wildly different genitals, both in the males (which, like most lizards and snakes, are blessed with a double penis), and in females (which sport a cloaca). Superficially, this could be taken to mean that they have evolved BECAUSE they have differently shaped reproductive organs. But it is not that simply, since the shape of the genitalia does not prevent species from hybridizing… Genital boffins are baffled.
