Sorry for the late response. I wanted to find time to do more research about this before responding but I'm gunnuh accept that it's not happening on a useful timeframe.

I'm not sure which Wikipedia article that is or if there has been revision between when you checked, I didn't find that in the Wikipedia articles for Telidae or Parthenogenesis. The Parthenogenesis article notes that it's controversial whether this is a threat to their ability to adapt.

So I may have been wrong with that example and I thank you for correcting me. I stand by the statement that evolution can get stuck in local minima but I may have been wrong about the Telidae.
