Science explaining the battle of sexes?

R. Dawkins takes notice of the comment made in a scientific paper written by  Schuster and Sigmund:

Briefly, then, we can draw two conclusions: (a) that the battle of sexes has much in common with predation; and (b) that the behavior of lovers is oscillating like the moon, and unpredictable as the weather. Of course, people didn't need differential equations to notice this before.

Schuster and Sigmund (1981), Coyness, philandering and stable strategies, in Animal Behavior, 29, 186-92. Quoted by R. Dawkins in the note of p. 153 in his 30th anniversary paperback edition of The Selfish Gene.
