Join Professor Anthony Martin, Ph.D., on an amazing exploration of evolution’s most important moments—the giant leaps that gave rise to nature's boundless diversity—in the course "Major Transitions in Evolution" from The Great Courses Plus. Complex life traces back to the Proterozoic eon, when simple one-celled organisms called prokaryotes evolved specialized structures and became new types of cells called eukaryotes. In this third of 24 lectures, Professor Martin investigates how this major transition took place, paving the way for the profusion of life forms explored in the rest of the course.
