Male Water Strider Evolved Specialized Hook to Grab Onto a Female's Eyes to Mate

All is fair in love and war, and especially the warfare of love. Locke Rowe of the University of Toronto discovered that male water striders have evolved its antennae into a specialized hook to grab onto a female's eyes in order to mate:

As the female skates over the surface of ponds and lakes, males will try to force themselves upon her. She resists by struggling vigorously. But in some species, males can avoid being thrown off with antennae that have evolved into antler-shaped restraints. They bend in on themselves and are loaded with an array of prongs and spikes that perfectly fit to the shape of a female’s head. [...]

The females have normal antennae. The males however, have “spectacularly modified grasping devices”, says Rowe. “They’re large, muscular, and fitted with spines and spikes exquisitely adapted for grasping – a long way from an insect feeler.”

Nice story about the antennae, but not a bit of information supporting evolution. No fossils with half formed hooks. Just some scientist backward engineering them by manipulating the genes. That isn't natural evolution. That is outside input by intelligent (but not wise) design.
Abusive comment hidden. (Show it anyway.)
