Context: <response>: Popper dey compare im views with di idea of di "hopeful monster" wey get big mutations for phenotype and e call am di "hopeful behavioural monster". After behaviour don change drastically, small but quick changes for di phenotype go follow make di organism fitter to im changed goals. Dis one dey make am look as if di phenotype dey change dey guided by some invisible hand, while na natural selection dey work in combination with di new behaviour. For example, according to dis hypothesis, di eating habits of di giraffe suppose don change before im elongated neck evolve. Popper compare dis view as "evolution from within" or "active Darwinism" (di organism dey actively try to discover new ways of life and dey on top quest to conquer new ecological niches), with di naturalistic "evolution from without" (wey get di picture of a hostile environment wey dey try to kill di mostly passive organism, or maybe segregate some of im groups).
