"When organisms encounter novel environmental conditions – a new habitat, a changed climate, a change in resources – they survive and persist (achieve realized fitness) where and if they “fit” by means of characters they already possess. In other words, successful establishment in a novel environment requires species having reaction norms that already include conditions in the novel environment. For the species to persist, colonists facing ecological novelty must achieve realized fitness within a more or less evolutionarily unfamiliar web of species (predators, prey, competitors, symbionts, etc.) using traits they already possess. Thus within any given ecological community, and depending on time and contingency, at least some traits relevant to observed species interactions will have evolved elsewhere under different conditions, but were later co-opted or exapted to form new, ecologically fit, interactions."Interessante analogia entre a biologia e a economia. Quando uma organização percebe que tem de mudar de vida não o pode fazer livremente, tem de ter em conta o seu ADN, a sua experiência. Um pouco como na "effectuation", começar pelo que se tem à mão.
O que me faz recordar Hausman e a sua frase "Os macacos não voam. Macacos trepam às árvores"
