The Red Queen hypothesis of why we need sex. Susceptibility to disease typically has a genetic component.  Since asexuals keep almost the same genes from 1 generation to the next, parasites can easily evolve to infiltrate their defenses, annihilating clones.   In contrast, sex, by mixing up genes, prevents parasites from becoming too well adapted to their hosts. Sex is an advantage because it breaks up gene combinations, creating a genetic version of a moving target.

Red Queen Hypothesis: proposes that organisms must constantly adapt, evolve & proliferate not merely to gain reproductive advantage but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment; intends to explain the constant extinction rates observed in the paleontological record caused by co-evolution between competing species & the advantage of sexual reproduction at the level of individuals;

Red Queen (extinction by pestilence)  -  organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but  to survive while pitted against ever-evolving opposing organisms in an ever-changing environment. Explains constant extinction rate and the advantage of sex reproduction. Chart: RQ at the genus level. The linear relationship between number of genera and the logarithm of survival times suggests that the probability of extinction is constant over…
