Life is dynamic, and things change: natural selection - adaptations, phenotypic traits, behaviour is a phenotype. Natural selection: two phenotypes, over generations, one phenotype is more successful than the other, how can this be selected upon, there (cid:272)a(cid:374) (cid:271)e (cid:373)orphologi(cid:272)al a(cid:374)d (cid:271)ehavioural phe(cid:374)otypes that do(cid:374)"t (cid:374)e(cid:272)essarily (cid:271)e(cid:374)efit that specific phenotype.
