The Development of Life: Life Through the Ages

In this episode we will learn about the geological time scale – what was the climate like a billion years ago and what living organisms existed on Earth at that time? Why did the dinosaurs actually die out? We discuss concepts such as Precambrian, Paleozoic, and Mesozoic, and learn what an Archaeopteryx is. We will explore all these things in the second part.
