The Development of Life: Early Life

What were the first living organisms on Earth? How did they work? In this episode, we travel millions – even billions – of years backwards in time in order to learn how Earth was created. We study the significance of the nebular hypothesis and how Earth has changed since its inception. We also discuss concepts such as stromatolites, organelles, and eukaryotes. What were the first life forms on our planet and how did multicellular organisms develop? We will learn all these things in the first part of Development of Life.
