  1. I am so loving all this work on the great oxidation event! I’ve been talking about it for decades and it’s great to have some high quality videos to share with the less informed😁 way more palatable than the usual scientific article or paper, although that is a staple of my diet😎 keep up the good work!🥳🎓🍻

  2. Thanks so much for posting this! The world sucks extra hard right now and it's wonderful to hear cool stuff to the sound of an awesome voice.

  3. Maybe a few little details (birds before, grass after) weren't quite right but this was the most satisfying YouTube thing I have seen in quite a while.

  4. Great video! Only one comment. Life would have never made it to become a simple bactaria. Some bacteria have made it to live amon us. Our neighbour, our manager… etc. Regretfully to say, but there are still too much amon us. 😉

  5. This is by far the best you tube channel I’ve ever watched! Everything about these videos is perfect! The narrator, the script, the visuals! I’m seriously blown away! 💜

  6. Yes, but how did the sexual reproduction evolve? How did cells develop halving their DNA without dying. How did these halved cells get the ability to merge to make a whole cell? I feel their is a big chunk left out in the end.

  7. Did you skip the proto-mitochondria? When did non-photosythesising oxygen-loving come about? Was it before or after predation? Otherwise great work.

  8. Thank you so much for this! This is very quality content, i enjoy this story and how it is presented. Subscribed right away, keep em coming 🙂

  9. You sir are high quality speaker. Nature is strange and fascinating. The smallest organism can change the face of a planet. Yet it's fragile and could disappear in the blink of an eye. And here you are, after billions of year of evolution. Think about all the unexpected events that led to you. From you parents meetings to the cell that divided in the primordial soup. It's been quite a journey. I'm burrying my grandma tommorrow, and that's how it is. I'll pray for her, and remember that she was part of that journey. And my childrens will have to continue it. And theirs, after i'll be gone t'ill the end of the universe. Life is beautifull and a poetic thing.
