Disparities in mate attraction that alone account for differences in reproductive success An important aspect of evolutionary biology is sexual selection. The nature and scope of sexual selection, however, have been debatable since Darwin first proposed the idea of it.
Recent debate has brought the fundamental topic of what sexual selection actually is back into focus. Incorporating female-female reproductive rivalry into sexual or natural selection is one example of this.
Sex roles are determined by differences in gametes: men generate significantly more plentiful, smaller, motile gametes whereas females produce relatively fewer, more nutritious, often non-motile gametes. There will be an excess of male gametes that will not fertilize any eggs since just one gamete of each kind is necessary to generate a child.
