Material has been added recently that muddles the page further, although the wording was imperfect before. I will revert since the previous version was a better starting point. A few points:
sexual dimorphism is not relevant to a discussion of the origin and function of meiosis. The important question is whether meiosis and sex arose as a way to repair DNA or because a diploid state provides protection from the effects of deleterious alleles.
meiosis should not be referred to as a stage, it is an event, or a process. It consists of several stages or phases, such as anaphase, G1, etc.
the current version says "The evolution of sexual reproduction only occurs in eukaryotic cells", is not a useful statement since ongoing evolution is not the subject of the page, rather ancient evolution is the topic.
it is not helpful to change "Meiosis is ubiquitous among eukaryotes." to "Sex, and hence meiosis, is ubiquitous among eukaryotes" because the essence of the theorizing about the origin of meiosis is that it may have arisen before sex arose in a form that we would call it that.
