On the contrary, there is alot of literature on this fascinating subject, many books and papers, TL;DR - as a first approximation: (1) In asexual reproduction, each successful offspring generates about 1 bit of useful information ("entropy") (2) In sexual reproduction, each generation of offspring from population n can generate on the order of log(n) bits of information Ref: Information Theory, Inference and Learning Algorithms by David J.
