The question "How did life first come to be?" gets a lot of attention in media. What we fail to understand is that for the vast majority of time that life has existed, more than 3.5 billion years, it has been exclusively single-celled organisms. Only in the last half billion years have multi-cellular creatures such as plants and animals existed.
This documentary focuses on these themes: how, approximately half a billion years ago, the first complex organisms came to be and how these organisms quickly evolved to later become all macroscopic life forms such as plants, insects and dinosaurs.
What else can I say? It is written and narrated by Sir David Attenborough: that should be all you need to know. This series opened my eyes to the fascinating period in time called the Cambrian explosion, and made it clear how far life has come in a comparatively short time. It is one of my favourite documentaries of all time, and I highly recommend it.
