Understand Evolution tells the sweeping story of life on Earth. From primordial beginnings and the first cells to viruses, bacteria, plants, fungi, and animals, this series follows the long arc of life as it changed, adapted, and diversified.
It explores how single-celled life evolved and how that life eventually gave rise to animal reproduction and complex traits. It is also the fascinating story of how two single cells—a sperm cell and an egg cell—can join, mix DNA, and divide again and again until a fish, dog, or ape is formed. It explores the evidence, the mechanisms, and the major turning points while tracing the rise of traits that shaped every species on Earth.
