I want to know the answer to the following question:
Which view of evolution emphasizing large changes in organisms' phenotypes does Popper oppose to his own?
All the background I'm provided with is that "Popper contrasted this view as "evolution from within" or "active Darwinism" (the organism actively trying to discover new ways of life and being on a quest for conquering new ecological niches), with the naturalistic "evolution from without" (which has the picture of a hostile environment only trying to kill the mostly passive organism, or perhaps segregate some of its groups).". Is that enough to answer the question?
Answer: no
