Bret Weinstein and Heather Heying join Bridget to discuss their latest book A Hunter-Gatherer's Guide to the 21st Century . They have a fascinating conversation covering how so much in evolutionary biology is obvious in retrospect, why an explicitly scientific and evolutionary understanding of who we are as humans doesn't take away the sense of awe or miraculousness of our humanity, and how the rate of change we are living through now is so great that there's really no comparison to any other point in human history. They discuss the Precautionary Principle, the function of religion, the fourth frontier, organic food, hyper-novelty, banishing your fear, what makes a good partner, and the Omega Principle.
