Economics and sex

Petty et al have drafted a paper "Why sex and why only in Paris?" The abstract says
No single question has been more central to our understanding of sex than the question of why a species reproduces sexually when asexual reproduction avoids the twofold cost of males. Surprisingly, an equally fundamental question has received virtually no attention at all. That is, why are there no triparental species in which an offspring is composed of the genetic material of three individuals?

I have no idea what this actually has to do with economics, nor why we are interested in this. Usually I think the most useless papers are usually written in game theory, but this one actually uses a statistical model.
