Things are seldom as simple as they seem. Religion, for example, is frequently cast as the villain or the hero of human society, when, in truth, like most human institutions, it is a little of each. I’ve read many theories on the origin of religion, and none has been completely convincing but most contain persuasive aspects while I’m reading them. After having read several books proclaiming the end of religion in the last several months, I just finished Matt J. Rossano’s Supernatural Selection: How Religion Evolved. Many books with a similar goal begin with the suggestion that religion may have had some biological utility for people at one time, but that we’ve outgrown our need for it and we should classify it with other obsolete, arcane concepts that have no further purpose. Rossano suggest that religion grew out of the need for social bonding and that we could not have become human without it.
Basing his ideas on genetics and anthropology, Rossano notes that even with our genetic similarity to chimpanzees there remain striking differences. Mostly they are social in nature. Many of the differences are reflected dimly in our primate cousins, but the human penchant for gathering in groups with ritual behavior to offset overwrought emotions applies only to us. That ritual behavior includes healing rites, something that Rossano suggests might be the earliest, shamanistic, religion. Back in my teaching days I’d been telling students that the earliest evidence for religious behavior dated to the paleolithic period. This is something I’d reasoned from the artifacts found in pre-historic communities. I was happy to find confirmation in a more competent scholar than myself.
While I’ll no doubt revisit some of the fascinating hypotheses of Supernatural Selection over the coming days, one point especially stood out on my initial reading. Religion is a communal phenomenon in what is a largely individualistic society. In other words, religion itself continues to evolve. Even the hermit in his or her cave is only considered religious in comparison with his or her less dedicated, secular compatriots living la vida de fe. Since religion is communal, Rossano suggests, it is impossible to argue someone out of their religion—based on perceived relationships as they are. Indeed, it seems that his hypothesis predicts a behavior we find only too evident when we prepare to line up at the polling booths, but which will immediately fall into the background again once the level is pulled.




The specific form of penny offerings seems to go back to Benjamin Franklin’s burial, at least in America. A few years back while in Philadelphia, I saw for myself that people still leave pennies on Franklin’s grave in Christ Church Cemetery. 
I recalled having seen stones on tombs outside Jerusalem some years back, and I even had a student bring me a stone from Israel to keep as long as I promised to put it on her grave after she died. This practice in its recent form is associated with Judaism, but again, it has ancient roots. The building of cairns, or piles of stones, is often associated with the Celts or the pre-Celtic inhabitants of the British Isles. On our many wandering through the highlands and islands we saw several Neolithic examples in Scotland, particularly in the Orkney Islands. The practice of putting stones atop the dead also goes back to ancient times. One plausible suggestion is that it was intended to keep the dead in their graves. A more prosaic conclusion is that digging deep holes takes more work than hauling over a pile of rocks.
