''.........Organisms which are not sentient, that is, have no mental life, display at most Level 1 reactions. Insects, worms, and other invertebrates react to noxious stimuli but lack the neurological capacity to feel pain. Their avoidance behavior obviously has a selective advantage in the struggle for survival and so is built into them by natural selection ....... ''

rephrase: Their avoidance behavior obviously has a selective advantage in the struggle for survival and so is built into them by natural selection.

rephrase: Their behavior has an *obvious* selective advantage .... and so is built into them by natural selection ....... ''

rephrase: Their behavior has an *obvious* preservation(selective) advantage .... and so is built into them by natural selection ....... ''

rephrase: Their behavior has an *obvious* advantage .... and so is built into them by a coo-coo-clock ....... ''

finally: Their behavior has an *obvious* advantage .... and so is built into them  ....... ''

'has an *obvious* advantage' and 'built into them' allude to the same fact, saying the same thing twice and thus guarantees the truth of the proposition, making it a rhetorical tautology. Especially the term *obvious*, facts such as what happens, happens are obvious, so are the tautological fact A or not-A. Explanations which are *obvious* aren't therefore falsifiable theories. Newtons inverse square law isn't obvious, it isn't a fact, but a falsifiable theory.
