Homo Sapiens doesn't possess those built-in impulses. Some sick members of society imprint that it on some others (usually early in their life), and with society putting some effort into it, that bad habit will be exterminated.
judging by your other comments, talking about evidence you probably mean your personal experience. Well, by the same token one would expect that people dealing with rapists would with the same validity talk about such Homo Sapiens built-in impulse too.
