What if the story of life on Earth wasn't fixed, but a constant process of change? In On the Origin of Species, Charles Darwin revolutionized science by unveiling the theory of evolution through natural selection. With careful observations of finches, fossils, and the struggle for survival, Darwin showed that species aren't static—they adapt, compete, and transform over time. The book wasn't just biology; it was a seismic shift in how humans understood themselves and their place in nature. Controversial then and still debated today, its ideas continue to shape science, philosophy, and culture. If you've ever wondered how the incredible diversity of life came to be, this episode will take you inside the book that changed the way we see the world.
