The crazy thing with Asari reproducing the way they do though is there are actual real animals that reproduce that way. In particular, there are a few species of carp that are all-female and reproduce by swimming into the middle of schools of other species, then literally use the sperm of those species to initiate what’s effectively cloning. As well, there are lizards that are facultatively parthenogenetic, so if no males are present they reproduce by (basically) pretending to have sex, which leads to hormonal changes that trigger clonal reproduction.
From this, I conclude two things:
1) Carp are kinky freaks
2) To put it simply, ‘life, uh, finds a way’
