Preferring to mate in a specific location does not seem 'random' to me. actually a rather interesting potential mechanism, perhaps adaptive

But mating no matter with which individual seems to signal genetic randomness. This is at least puzzling.

#Darwin in the face - haha. Your summaries make me chuckle, Rolf, almost as often as they illuminate. I do wonder if the conclusions put forward by this experiment overstretch the results, though I'm not an#evolutionarybiologist -
The idea of female choice being adaptive and directed at males' "good genes" has come under fire:https://twitter.com/DegenRolf/status/863454791283994627 …

Potential mates don't go around thinking "Hey those are good genes. I'll select them."
-
They simply select, and BY VIRTUE OF THE SELECTION, whatever they selected is defined as being "good genes".

I recall a study in which several male dogs were tied to different posts and females mated with choice. And later they selected same dog.

If once there was both proximity and sexual readiness mating occurred, then "randomness" would be the result of the advent of proximity.

Hard to generalize from captive behavior to behavior in the natural environment, where there is unlimited freedom and interactions

But research in a seminatural environment is getting closer. Here a beautiful study showing that male or female preferences (based on various sociosexual interactions) were not strongly related to fertility. https://ac.els-cdn.com/S0031938415300196/1-s2.0-S0031938415300196-main.pdf?_tid=98720c20-f57b-11e7-bf84-00000aab0f01&acdnat=1515529865_c1356975c0f921965c98af7fc07a1940 …
