Origin and early evolution of life with William Martin | Reason with Science | Hydrothermal Vents

[@kamrupexpress]

Jitender , your channel is such a wonderful pastime for me. So much to learn. Though I am a mathematician by profession you can say that I am very obsessed with Charles Darwin and Evolution. I would be grateful if you could have Prof. Janet Browne on your shows. I also have a suggestion that these wonderful interviews can be put together into a book specially the ones on biology with providing a little explanation of the technical issues in the beginning of each chapter. I am sure it would be a best seller in the scientific community. You are doing a great job. Joydeep Dutta Professor IIT Kanpur

Thank you Joydeep for your kind words. I will definitely try to contact Prof. Janet Browne :)

This channel deserves more views

Wow. For once, I truly believe Bill Martin has it--the origin of life. This makes so much sense. I particularly like the compartmentalization that happens within these vents: they're like pre-made cell membranes to get everything going in an isolated environment. Finally. I'm glad I lived long enough to see this solution. Wow, and I love the idea of two separate escapes that led to two separate types of life. So it was still a very singular rare type of event. Perhaps it only reached the escape peak twice. Could there be "competition" within larger/later compartments: competition for compounds generated from lower compartments? Could the "evolution" and natural selection be occurring before cells escape? A "fight" for resources that led to optimizing the system while it's still within the vent compartments? And perhaps leading to lipid formation as some sort of optimization within the compartment for the sake of surviving there and using more resources. Almost like a buffer within the compartment: a buffer against the compartment itself, or perhaps against the relative acidity threatening to get into the structure from the outside? Wow, very interesting.

This is amazingly rich info source thank you!

Hi Jitender. I only came by chance to your video. In fact I had a long discussion with Chat-GPT on the origin of life and found there that prof. Bill Martin is investigating some aspects in University of Düsseldorf, where I was led to this video. What I am really interested in, is if the forming of life is straight forward, why can we not see it happening every day at a hydrothermal vent as a continous process ? I mean, it should be a continous process and not one in a lifetime, since else entropie would always destroy anything build. Am I correct ?

Hi, it's a good question. So far, it is conceived to be dependent on the conditions at the planet around that time. We still need a better understanding of the chemistry at hydrothermal vents. I asked similar question to Nick Lane: kzbin.info/www/bejne/j6DPep6hlNR9mqs

Presumably the hydrothermal vents are now populated by anaerobes which consume any geochemically derived organics so they can't combine into new lifeforms. I suspect the ocean pH has changed over the eons as well as the oxidative state meaning the equilibrium of the H2/CO2 couple no longer sits on the reduced side.

It seems impossible to me to get molecular evolution without having first evolved compartmentalization. If all the biochemicals are in a soup, even if a rare efficient machine like a DNA polymerase were to have arisen, would not that new machine be lost without some way to have a cell selected for? how can biochemical evolution occur without selection?

I think Darwin's original "warm pond" idea is simple and sweet. Modern biologists overthink the origin of life. Keep it simple.
