Hello all! Hope you are enjoying the video. Quick correction - the image of frozen Earth does indeed hide the shape of North America. Oversight on my part. Obviously wouldn´t have been under there back then! Apologies.
-
"Ha ha! Stupid bacteria... imagine poisoning your own atmosphere out of greed and killing everyone including yourselves because of short sightedness! Sure glad we have brains to prevent that..."
-
To all the microbes that died during the great oxidation event... Rust in peace 😔
-
Most of this I've read or heard before, but the realization how fragile life really is, shocks me every time. We're living on an unimaginable graveyard of billions of wiped out species. Think about that.
-
The person responsible for this masterpiece is extremely talented. Better than what’s on Discovery for sure.
-
It takes a masterful narrator to make one feel empathy for anaerobic bacteria and cast oxygen as a villain. Well done, Sir!
-
I used to know a lot about the Great Oxidation Event, but my memory is a little rusty
-
What a great series! We are in the era when online content is more interesting than stale television. Great job!
-
It’s amazing what humans have been able to learn and accomplish in a very short period of time. I’m always blown away by the fact that the earth has lived billions of different “lives”.
-
Humans: We are the most disruptive species ever. Cyanobacteria: Hold my carbon dioxide.
-
thoughts and prayers go out to the families of the bacteria that were rusted to death
-
This is so well narrated that I didn’t even notice there were no subtitles, despite normally preferring them if at all possible. Masterfully crafted.
-
At 2:50, the video states that the Chicxulub impactor was 80km wide. Consensus today puts that size at roughly 10km in diameter (e.g., about the size of Everest).
-
"In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move." - Douglas Adams
-
I am a microbiologist and studied anaerobes and Clostrida in particular. I wrote my Ph.D thesis on the effects of oxygen on these bacteria. There is a spectrum of oxygen tolerance amongst these bacteria. They are all Eubacteria, modern microbes not Archea. I enjoyed you presentation very much.
-
I'm glad we made it through that one!
-
I took a couple of college geology courses in the early 1970's, and the oxygen catastrophe was not mentioned. Therefore I assume this is newer science. The hot controversial topic of that time was a radical theory called "Plate Tectonics" - a process we humans experience many times per year on this planet.
-
This sounds so much like a made-for-TV documentary. I've seen a fair number of long-form educational videos on Youtube, and none of them made me feel like a kid watching the Discovery Channel the way this did.
-
The concept of 2.4 billion years ago is difficult to imagine. That we are lucky enough that this blue planet has been safe for this long is hard to believe.
-
The asteroid that killed off the dinosaurs was estimated to be 10 to 15 km in size, not 80 km as is stated at 2:52.
