Bret Weinstein and Heather Heying, the hosts of the renowned DarkHorse Podcast came to Prague for the book launch of the Czech edition of their book "The Hunter-Gatherer's Guide to the 21st Century". Seizing this unique opportunity, our institute's director, Adam Růžička, invited them to our podcast, Společná řeč. For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our woes is clear: the modern world is out of sync with our ancient brains and bodies. We evolved to live in clans, but today most people don't even know their neighbors' names. Survival in our earliest societies depended on leveraging the advantages of our sex differences, but today even the concept of biological sex is increasingly dismissed as offensive. The cognitive dissonance spawned by trying to live in a society we're not built for is killing us. In this book, in Czechia under the title "Průvodce lovce-sběrače po 21. století", Heying and Weinstein cut through the politically fraught discourse surrounding issues like sex, gender, diet, parenting, sleep, education, and more to outline a science-based worldview that will empower you to live a better, wiser life. They distill more than 20 years of research and first-hand accounts from the most biodiverse ecosystems on Earth into straightforward principles and guidance for confronting our culture of hyper-novelty.
