We all know people who have suffered with cancer. It's a major affliction of our modern world and many scientists are studying it closely to find a cure. Karl Krueger is one such scientist who has spent much of his career in cancer research. Today, host Casey Luskin speaks with Krueger about his work and what cancer can teach us about the limits of Darwinian processes. In his tenure at the National Cancer Institute, Krueger had a front-row seat to cancer research progress. After reviewing countless research projects and mountains of data, Krueger learned that cancer doesn't create new features at the molecular leveI, it degrades them. And breakage of aboriginal design is a hallmark of Darwinian processes. Krueger explains in this illuminating discussion.
