Belief, superstition, and conspiracy... Where did they come from?

How did our species evolve from stone axe chippers living in dank caves to the architects of artificial intelligence living in air-conditioned high-rise penthouses?

As author Jim Bucko explains, our tool-making capability seems to have preceded and then paralleled other developments in human language, art, ritual behavior, and reasoning which have led us to today, and set us up for great leaps ahead tomorrow.

Written in terms everyone can understand, this is a wondrous journey of discovery about the evolution of our brain and why we have developed mental abilities including religious beliefs, conspiracy theories, and superstitions.
