Chris Packham presents a landmark five-part science series exploring the extraordinary story of animal evolution. Across millions of generations, every creature alive today has been shaped by survival, chance, adaptation and extinction - from bats with ultrasonic hunting abilities to peacocks transformed by sexual selection and kangaroos whose success lies in unexpected evolutionary advantages. Using cutting-edge CGI, genetic research and vivid natural-history storytelling, Evolution travels deep into Earth's past to reveal the strange ancestors, dead ends and dramatic turning points that created the animal kingdom we know today. It is a visually ambitious, accessible journey through the tree of life, showing how one original spark of life became the astonishing diversity of creatures that share our planet.
