In this episode, we explore the revolutionary ideas that forever changed how we understand life on Earth. Through excerpts from Darwin’s On the Origin of Species, we unpack the principles of variation, natural selection, and the struggle for existence—using examples from domesticated animals, ecosystems, and fossil records. We also examine the objections Darwin faced, from the mystery of missing transitional forms to the complexities of instinct and hybrid sterility. It’s a scientific and philosophical journey into how all living beings are connected through descent with modification.
