Since biology is not my profession, I am not equipped to determine exactly where the threshold of possibility is, but we can rest assured that the general odds against special evolution are sufficient to demolish the idea.
Biology is my profession.
What is so “special” about “special evolution”?
Evolution happens.
If I took a single bacteria, allowed to to form a colony, then plated that colony on ten different petri dishes and subjected them to ten different stresses would they not EVOLVE to counter these stresses?
This adaptability of life due to the ability to select from genetic variation has been seen in thousands of experiments.
In fact one of the responses of these bacteria to stress is to UPREGULATE genes that will increase the mutation rate and DOWNREGULATE genes that will repair mutations.
Why would they want to do so?
