there are a few valid points in a. lima-de-faria's "evolution without selection form and function by autoevolution" but unfortunately they are embedded in the far-fetched examples, illogical progressions and disjointed lists with which the author attempts to demonstrate that evolution occurs not by natural selection but by autoevolution. lima-de-faria's major problem with natural selection seems to be that it is not popperian enough. the term is abstract and the concept is impossible to prove with a controlled scientific experiment; as lima-de-faria states it 'selection cannot be weighed or poured into a vial. as such it is not a component of the mechanism of evolution' (pp. 7, 312). this is a good example of the type of non sequitur that is abundant in this book, in that weighability and pourability are not criteria that come to mind when evaluating theories, nor is autoevolution itself especially weighable or pourable.
