Without sex, what is a species?
I think one of the ideas is that sex between a couple of the same species should be able to produce fertile offspring of the same species.
This sexual reproduction will stimulate variety by producing lots of different combinations of genes, and over time the production of new species.
So quite why are there so so many species of fungi?
Are we just going to say, if the dna is unique then it is a species. I bet there are tiny differences everywhere. Or if there is some visible difference which propagates? In which case there would be far too many separate species. Or significant differences?
Sounds dubious to me.
