Re: Existence of life
That’s a question you need to answer for yourself. If you have evidence, then you don’t need faith. Opinion isn’t evidence! Using a holy book to verify it’s own claims isn’t evidence!
By the way, it’s not my definition…it’s the accepted definition.
The question you’re asking, for clarity’s sake is: Without the presence of one of the stimuli, can mutation occur?
If that is your question, then the answer is yes.
I don’t understand your second question. You’re asking if you can have change without change…that’s not a reasonable question.
