The Microbial Basis of Life
Вставка
- Опубліковано 12 жов 2022
- Single-celled microbes underpin all life on Earth, and even complex organisms like humans retain a surprising amount of their microbial heritage. Life began when free molecules became encapsulated in a lipid membrane and transformed into a self-replicating entity. Subsequently, multiple cells came together, forming a remarkable symbiosis that ultimately led to all complex, eukaryotic, cells and laid the foundations for multicellular life.
Understanding this microbial legacy has some surprising implications, such as explaining why some antibiotics have unwanted side effects.

Excellent. Looking forward to the next episode.
This was a very interesting summary, I look forward to catching up with the other episodes. I studied paleontology and evolution about 35 years ago, and we knew a lot of this but the progress is impressive.
Brilliant, engaging, playfully teaching. Loved it all
Glad you enjoyed it!
May I suggest an alternative to the "eating events". It seems reasonable that the archaea and bacteria originally formed an exo-symbiotic relationship and evolutionary pressure meant that staying together was vitally important and so evolved a mechanism to do so.
Hmmmm. A very slow start covering very basic stuff those interested in the topic surely know. But by the halfway point, he hits his stride and it becomes quite interesting. I have now seen videos 2 and 3, and each is engaging. These are more than just a review of microbes, but an intro into new ways to apply what evolution as done in the microorganism world, and how we are on the verge of developing new technologies to make use of it. I am eagerly looking forward to the remaining three lectures.
Thks
The simplest cell can afford to operate with only 580,000 DNA nucleobases only because it lives in an environment which provides essentially everything it needs whereas the first cell would have had to manufacture all of its own components and therefore would need much more DNA.
Beutiful lecture as always enjoy it every minute of it
Excellent lecture full of valuable information, amusingly presented.
If I were present in the lecture I would have asked:
In the Earth's first mass extinction, caused by oxygen, were the species all microbial?
I was aware that free oxygen killed most living things when it appeared, but had poor context.
I imagined the things killed by oxygen would be things I could see, and if I was Doctor Who I would see living things if I got the date right.
No, the Earth was entirely microbial at that time and for long afterwards.
@@sentientflower7891 Thanks for answering. Is there a fossil record of the mass extinction? Are there any internet sources for the event, do you know?
@@glynwelshkarelian3489 it is the first mass extinction event and there are entire lectures dedicated to it, along with books and articles and all sorts of scholarly articles.
Isn't science amazing? As much as we discover the best scientific principles in biology, chemistry ⚗️ physics, geology anthropology etc. We see scientific creation which no species ever created. Divine Creation and its scientific reality ✨️ how beautiful.
“Divine creation?” Whish mythology are you trying to sell us? I’m partial to the Hopi creation myth myself!
Mushrooms are also an integral part of a healthy biome.
I love shrooms.
Ikr. Great on pizza.I😂
