Thanks for the support. It helps to have someone point out the same concepts I've been trying to explain, but with a different perspective.

You're welcome. And thank you for all the information you've shared. I'm not a scientist myself--more of a science fan and occasionally a science writer. So I'm enjoying what I'm learning. I never knew that a challenge for experimenters with...was it bacteria?...is to keep them from evolving. That's pretty cool.

That's a challenge when working with any microorganism or cell line. Explaining how one controlled for evolution is SOP when doing those kinds of experiments.

Ugh, I'm sorry, I made a horrible grammatical error in my previous response.

Correction: Explaining how one controlled for evolution is SOP when communicating the results of those kinds of experiments.
