Making Sense with Sam Harris

#382 — The Eye of Nature

Sep 6, 2024
In this engaging discussion, Richard Dawkins, a renowned evolutionary biologist and author of The Genetic Book of the Dead, explores the profound connections between genetics and ancestral legacy. He delves into epigenetics, the complexities of predicting phenotypes from genotypes, and the ethical implications surrounding genetic engineering technologies like CRISPR. Dawkins also reflects on human cultural dependence for survival, the role of symbiotic viruses in our evolution, and the future of resurrecting extinct species. A thought-provoking dive into the science of life!

  • Richard Dawkins highlights that our genes act as a palimpsest, encoding ancestral environments and adaptations over evolutionary time.
  • The podcast discusses the distinction between genotype and phenotype, underscoring the limited role of epigenetics within Darwinian evolution.

Deep dives

The Genetic Book of the Dead

The concept of the 'Genetic Book of the Dead' is introduced, which likens genes to a palimpsest—a historical document that contains layers of erased and overwritten information. Richard Dawkins suggests that our genes serve as an encoded record of our ancestral environments, capturing adaptations from past eras. Future scientists may potentially decode these genetic histories, allowing them to understand how different factors influenced evolution over time, such as the transition from water to land by ancestors. This notion illustrates that genes not only dictate physical characteristics but also offer insights into the evolutionary path of species.
