Cara is thrilled to have the opportunity to continue her conversation with paleontologist, geneticist, anatomist, and popular science author Dr. Neil Shubin (Your Inner Fish, The Universe Within). They discuss Tiktaalik's place in our evolutionary past, along with new technologies and techniques that continue to unify Darwin's prescient theory and provide new clues to the great tree of life here on Earth. Also included: answers to brilliant questions asked by previous Talk Nerdy guest, young Stella Krone. Follow Neil: @NeilShubin.
