Creationists just can't keep things in context.
No educated person claims that evolution is the explanation just because it's reasonable.

My statement above is consistent with what I have said innumerable times in this forum; namely, that unless something produces hypotheses that are testable, then it isn't addressable by science.

We can debate all day about the reality of altruism (or free will), but as of this moment, neither has been fully answered by science. I say this in ignorance, actually. I haven't actually been looking at the evidence here. And this is something that marks a significant difference between myself and you, anyman - I actually admit that the reason I may be unaware of any evidence that decides the issue of altruism is that I haven't actually looked.
