From an earlier post (Mike Summers):

********** Let me reiterate ,and I think you will agree, racism does exist! Since it does, the theory of evolution and its alleged process infers that it (racism) had to be selected for. Logically then any act of racism or violence is due to selection processes at work. Persons that were killed were obviously, unfit and were not selected for.There is no explaining "it" away! **********

While this is true up to a point, there is an additional point missed here. That racism (or any other trait of an organism, physical or behavioral) exists today does not mean that it is being selected for by evolution today. It means that at some time in the past, it was selected for. We humans carry a lot of evolutionary baggage. Some we have to live with (an appendix, our dissappearing third molars, our bad backs, etc.) but others, particularly behavioral traits, we do not have to live with. Religion, along with other systems of morals and ethics, is one of the things that lifts us up beyond our evolutionary heritage.

Also, I hope no one makes the common error of thinking that races do not exist, therefore racism should not exist. Races, even human races, are a biological reality. Our behaviour towards those of other races is not biologically determined, only, perhaps, biologically suggested, an echo from our past. We are free to behave differently if we choose.

How are behaviours selected for via evolution when the mechanism of selection is genetic.... Are you suggesting that behaviours are coded within our genes? (The same as what Dawkins goes on about... the same thing which you claimed to not agree with?)

The specific behaviours are not coded, of course. But the ability which enables the behaiours certainly is. And culture today has largely replaced genetic change in our evolution - perhaps because it occurs so quickly relative to the usual course of genetic evolution. The basic "flight or fight" response, for example, originates in the hypothalmus, and is a reminder of our far distant evolutionary precursors - at least 300 million years ago. And we still rely on it to some degree, especially in the absence of time for careful thought. "Us or them" is just another facet of that same response.

This doesn't address what I was getting at. You claimed on another thread, that you do not believe Dawkin's claim that our behaviours are determined via our genes... Yet before you were talking about how behaviours evolve, yet considering that evolution is a purely genetic phenomena then you are making the claim that our genes do determine behaviours. Which therefore demonstrates a contradiction within what you claim between thread to thread, (anything to get those damn Creationists I suppose eh...)

You attempt to dodge this by claiming

"The specific behaviours are not coded, of course. But the ability which enables the behaiours certainly is"...

yet this undermines what you said about behaviours evolving.

"That racism (or any other trait of an organism, physical or behavioral) exists today does not mean that it is being selected for by evolution today. It means that at some time in the past, it was selected for."

Again I ask, which is it? Do behaviours evolve?
