Except that the question specifically asked.....”How does speciation explain drug resistance?”
NOT *How does *the Theory of Evolution* (or natural selection) explain drug resistance?*
You never answered the question. You constructed a strawman and proceeded to address that, not what was asked.
If you take responsibility for what you write, you have to take responsibility for not answering the question asked.
Why should I? I do not think that speciation has anything to do with drug resistance. Natural selection has. It's YOU guys who are trying to force the discussion in a direction that would enable you to construct a strawman.
He did answer the question. It is just that you did not like the answer and are now moving the goalpost.
This is a very common creationist/i.d. tactic.
Whether you choose to accept it or not the fact is that speciation is a part of the evolutionary process. This has been demonstrated by direct observation.
Your personal incredulity does not change the facts.
