One quote from the Real-life section says:

"Self-referential example: At one point, this editor had to remove text from another trope description stating that while a One Gender Race was plausible because there are examples of parthenogenesis in real life, this was "rarely seen beyond the reptile stage." Headdesk. "

I seem to be missing something. What exactly is the problem in that claim?

From the description: "Another popular form involves something evolving while still alive, on its own. While individual cells can mutate, as can the entire life form, this isn't evolution, but simple mutation. Evolution is defined as a population/species wide event. So one person cannot super evolve, as above, into the what would happen in the future."

So, what would be a more accurate way to call such a phenomenon? Mutation sounds quite bland, and covers both beneficial (what the phenomenon is) and deterimental (what it is not) cases.
