Pythagoreans -> Essenes -> Christianity -> Darwin ?
It recently came to my attention that Jesus may have been a member of the Essenes, and that the Essenes may be an offshoot of the Pythagoreans. The Essenes are suspected of being responsible for the dead sea scrolls. The Essenes were vegetarians, and Jewish books that allowed for eating meat, or slavery were seen as fiction by them. As Darwin was a Christian there seems to be the possibility of a direct line between Pythagoras, and Darwin.
