I guess I come from the "plesiomorphic" tradition :-). I don't think it is
fair to consider myself guilty of something that someone else did (Adam).
You mean that all the aborted children in the US today are going to hell
even though they never had the chance to do something, good or bad?
Anyway, evolutionists agree that there is a "human nature" and that it has
been shaped by natural selection over millions of years. How does this
human nature relate with the biblical concept?

I just gave a simple example to illustrate the fact that our genes
influence a lot our behavior. I know that genes do not *determine* whether
or not someone will be a drug addict, but they certainly play a
significant role. This was established in many studies of twins separated
at birth, for instance. I can give you some interesting references, if you
want. Many behavioral characteristics (novelty seeking, depression, drug
addiction - things that we consider parts of our "soul") have been shown
to be influenced by the metabolism of serotonin (e.g. prozac blocks the
receptor of serotonin). It seems that we are not *completely* free to do
whatever we want. This has some important implications about the way we
think about free will.
