about how evolution works; with no challenge (Evolution)

dhw: There is no disagreement here. You are repeating my own arguments in your own words: "environmental changes cause modifications" = adapt; “how complexity advances”, “increasing complexity” = my “innovations”; “very specialized process” and “certain groups of organisms” = my “exceptional individuals”. The only difference between us is your insistence on “a designed evolutionary plan”, whereas I would argue that the whole process smells of organisms doing their own thing.

Instead I am suggesting that this history can be explained by the fact that some organisms adapt to changing conditions, others fail and so die out, and others find their own ways of exploiting new conditions and “complexifying", as dictated by their individual ability to master changing conditions, and not by some overriding anthropocentric purpose. -Based on your worry about an IM with guidelines, I went back to this entry. What occurred to my was the obvious appearance of organisms changing their phenotype for no apparent reason. How many species modify and there are no environmental challenges? I think humans are one prime example. What I am claiming is that it is obvious some changes and advances are not due to stress, but simple innovation. The whale series is another example. The changes only served to complicate the physiology of the animals as they progressed from land animals to sea-dwelling whales. Natural selection played a role but initial stress didn't as far as can be told.
