I’d equate that theory to the virus that becomes immune to a vaccine. Very plausibleWhat people who dismiss evolutionary theory do not understand is the concept of deep time.
Given enough time anything is possible. I'm currently reading 'The Rise And Fall Of The Third Chimpanzee' which makes some interesting points about human evolution. For millions of years we stagnated culturally and then some tiny genetic anomally happened and we had muscles and nerves and a palate that allowed for speech. And then we really took off.
We were all modern humans by 60 000 years ago.
The hard thing to understand about the theory of evolution is deep time. We only really think of time in terms of one lifetime.
Maybe 100 years.
We can just about get our head around the Roman or Egyptian times (5000 years max).
It's when we are faced with 5 million years or 5 billion years that our idea of time gets confussed.
It's like Einstein's stuff. We are used to time at below light speed where physics is Newtonian. Get to light speed and weird stuff happens.
So given enough time tiny changes begin to have big spin off effects that mimic intelligent design.
