Behaviour's not part of the physical world, bw, it's got effect but it's not a _thing_. evolution's a theory with some bits of evidence fossilised in physicality. science basically _is_ the scientific method; otherwise it's speculation and philosophy.
bob, never heard of phycology, care to explain that? pathology is the study of disease- what causes it, how the symptoms come about, and those are effects coming from physical things. studies of behaviour and emotion- i grant you that one. but they come from physical causes, indirectly.
fp: universe has several sets of laws but only physics happens to have direct physical effect.
(i'm not trying to be annoying or whatever bob, but how can anyone have a decent discussion if you're only allowed to ask questions?)
