Too many good-smelling males is not good

Typically, I would not take the journalistic liberties I’ve taken here. But this article prompted me to throw caution to the wind that’s distributing our pheromones.

Natural selection limits how many attractive males can exist in a population

We certainly cannot have all males smelling as good as you do after you become human pheromone-enhanced. Nature won’t allow it, at least not in flies. Men might still benefit from pheromone-enhancement in short-term endeavors, nonetheless. Species survival isn’t always the most important thing that’s on our mind.

Genetically engineering male flies to release highly attractive pheromones worked — for a few generations. Females were more attracted to them. Seven generations later, however, the genetic engineering seemed to have no effect. “The authors conclude that being overly attractive must carry a disadvantage…”

I’m not sure how journalists translate these research findings to mean that there are limits on “…how many handsome men can exist in a population.” But I’m relatively certain that pheromone-enhanced men are not concerned with the attraction of other males who arrive on the scene seven generations later. Pheromone-enhanced attraction in most men is a here and now kind of thing, as we have reported in our findings from recent research.
