Frazzled UBM - "...rather than identifying those elements of Christianity that have pagan roots it would be easier to identify those that don't as they would be far fewer."
I dunno, something tells me you wouldn't have much left to work with.
Frazzled UBM - "I think you are on to something - certainly the Bible and Christianity in general are full of plagiarism or at least taking soemthing from another religious tradition and adapting it..."
cofty - "Chapter 15 of Susan Blackmore's book 'The Meme Machine', is titled 'Religions as memeplexes'."
While I get what both of you are saying (and, in fact, agree with you), I was actually talking about literal reproductive advantages; as in the propagation of genes i.e. sex (which was why I suggested that the idea seemed initally counterintuitive).
Before anybody says "Whaaaaa???", stop and think a minute.
Humans are essentially tribal creatures i.e. pack- or pride-oriented animals, and we are all - subconsciously or otherwise- concerned with our status or position in the group.
Why?
Time and again, biologists have observed that in pack/pride group dynamics, it's the alpha leader's' genes that dominate and - more importantly - are passed down to subsequent generations, because the alphas are the ones that mate the most (either because there's only one alpha of a certain gender present, or because he/she physically prevents competitors of the same gender from mating).
The vast majority of human organizations are heirarchal, just like a wolf pack or a lion pride, and for all their talk about sexual restraint, (male)leaders in religious organizations - more often than not - have far more sexual opportunities than the rank-and-file, simply because individuals in leadership roles naturally attract more sexual partners.
We're (arguably) wired that way psychologically.
Genes don't care whether a certain action is viewed as moral or otherwise, their goal is simply to propagate, and it's pretty clear at this point that they have a significant impact on our behavior, whether we're aware of it or not.
Is it so much of a stretch to suggest that religion evolved as yet another way for competing genomes to gain a reproductive advantage over their competitors?
