To appreciate this statement, one has to be quite clear about the biological notion of adaptation. It is not—as one is often led to believe—an activity of organisms or species. It is the result of natural selection and refers to the ability to live and reproduce in the present environment. We can visualize it with the help of a metaphor: the environment “selects” in the manner of a screen used to grade gravel: the screen admits what falls through and discards what does not. Similarly anything that passes through the constraints set by the present environment is adapted, or, as evolutionary biologists sometimes say, everything that survives is viable in the given environment. But just as having slipped through, does not tell the pebbles anything about the screen, so, to have survived does not tell the biological organisms anything about the constraints they have not met, i.e., the constraints that eliminated those that could not survive.","highlights":Ӷ^"jQuery321091777439976599082":^°°Ӻ,"text":"","order":"mw-content-text","category":"Argumentation2","data_creacio":1564141466193°
