It's important to say that evolution isn't versioned, and what we're observing isn't finished. We may be looking at an evolutionary dead-end. Which is to say that if eating the male is an evolutionary development, it might a poor one. There is no logic to evolution. No decisions are being made. Evolution is reactive, and the surviving lineages may only be responding effectively to some of the external forces. Evolution doesn't happen at a species level, it happens at the individual level and has downstream effects on the species. We're seeing evolution in action. Tragically, we (individually) won't be around long enough to observe the changes in another 100 or 200 or 1000 generations.
