I, for one, cannot see how things can be orchestrated thrust by thrust, whether consciously or unconsciously. I don't believe the Blind Watchmaker had such fine tuning to work from in the EEA, let alone in our present environment. I for one think that unconscious calculations at this level of specificity are just bioscience-fiction. That sounds a little more believable to me. Or it was those who were least inclined toward a long-term relationship with that partner who put up the biggest fight.
Men are descendants from urgent ancestors.
That's if you average across the honest courtship matings and, say, multiple rapes in wartime. I was sceptical about the data here. Again, there might be many men who experimented with homosexuality, perhaps when they were young, but grew into ordinary heterosexuals. One needs to see the stats. In any case, these data need to be analysed much more closely before this conclusion is to be believed.
