Meditate on It

Could ancient campfire rituals have separated us from Neanderthals?

A couple hundred-thousand years ago—sometime after our hominid ancestors had controlled fire, but long before they were telling ghost stories—early humans huddled around campfires to meditate and partake in shamanistic rituals. Today, when we slow down for a yellow light, recognize a dollar sign or do anything, really, that involves working memory, we have these ancient brainstorming sessions to thank.

That's the somewhat controversial connection psychologist Matt J. Rossano is making. Ritualistic gatherings sharpened mental focus, he argues. Over time, this focus strengthened the mind's ability to connect symbols and meanings, eventually causing gene mutations that favored the enhanced memory we now possess.

"We have decent evidence that shamanistic rituals may go very deep into history, and that these rituals might have had positive psychological effects," says Rossano of Southeastern Louisiana University, whose theory appears in the February Cambridge Archaeological Journal.
