Sexual arms race

The Natural History museum has a fascinating news story about sexual arms races in diving beetles.

Apparently, every time male diving beetles evolve better suction cups on their feet to hold on to females during mating, the females evolve countermeasures to decrease the effectiveness of the suction cups. This is because the optimal time, length or the number of matings is not the same for males and females.

“…wonderfully droll, witty and entertaining… At their best Carter’s moorland walks and his meandering intellectual talk are part of a single, deeply coherent enterprise: a restless inquiry into the meaning of place and the nature of self.”
