Yes, it does appear that invasive species don't suffer much from the lack of
genetic diversity. I wonder if you were to compare the genetic diversity of
early generations to later generations, whether the results would be close or
identical, or whether you would actually find MORE diversity over a few
generations. Moreover, if you found that such a population had sprouted new
genetic material, whether those same genes would be found in other populations
which are isolated from the first one.

Sorry, this thread is wandering a bit and I guess I should think about shutting
it down.

Where am I going? And why am I in this handbasket?
