The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let’s journey back to the origin of life, as best as we know it, from the RNA world do the last universal common ancestor of everything alive today.

The origin of life… it's a big question. Maybe the biggest.

Head to PBS Space Time and Eons and watch the rest of this collab!

As a student of bioinformatics I must say:
Probably one of the best videos on this topic. There is way to much old or misinformation on the internet, it's actually quite infuriating.
Thanks for this vid guys!

I was not only surprised, but deeply gratified with the content of this video. As a long-time watcher of science and science news, and an academic who followed the fortunes and misfortunes of the philosophy of science, I found myself deeply engaged in a play by play story of the beginning of life far more plausible than those preceding it. The cooperation with Eons and Space Time was well done. This trio of PBS channels has outdone themselves recently with well-done documentary and explanatory work. I know this show is a bit older, but it encapsulates a wide variety of issues at the forefront of scientific discovery. Kudos to these producers.

This video was pretty good but in multiple places it is said that life is a "closed system". In fact, the opposite is true: Living things are definitely open systems (thermodynamically speaking) and they would not be able to stay alive if they were not. I think what you meant to say is "enclosed systems" or some sort of "enveloped systems", i.e. they have a boundary between the interior and the exterior of the cell. We like to call them "organization", since it is this very feature gives the general shape of the organisms.

And it makes a clear distinction too: Viruses aren't alive because they have organization ("enveloped system") outside the host cell but they do not have the machinery, or "activity" to sustain their order. The moment they find a host cell, they somewhat gain this activity by stealing the machinery of the cells they infect - but this time they lost all of their "organization". So life requires "activity" (to sustain order, i.e. "metabolism") and "organization" together to create life.

Everyone is asking "what is life?" but one is asking "how is life?"

These are timeless topics. Still wonderfully informative after three years.
