This is the specific mechanism of your denial -- to 'rename' adaption.
The changes that occur in species due to natural selection is called 'evolution'. You don't like the word, for reasons you're not entirely sure of, so you play with the words until you've gotten rid of the threatening word 'evolution'. You agree with the specifics of the theory, but don't like one specific application of the theory, so try and discredit the entire theory.
But you can't ignore the truth. Adaption changes the species fundamentally. And enough small changes to a thing, and you will have a fundamentally different thing.
You say you don't believe in 'evolution', but do believe in natural selection.
What an amazing self-contradiction.
If you use MS Windows long enough, even after all the crashes, and fatal errors, it will not become UNIX.
No, no, no. Evolution is about the descent of one species from a simpler, less complex species. In fact Darwin for a long time did not even use evolution to describe his theory he called a theory of descent. In fact, adaptation is in a way a contradiction of the whole evolutionist ethos. If a species can adapt to its environment without transforming itself into another species - what need, what necessity is there for it to go through the long, dangerous, indeterminate process necessary for it to evolve as evolutionists claim it happens. The answer is that there is no need at all.
