How Did Life Begin? - Mysteries of Life #1

How did life begin billions of years ago? Did it start somewhere in the deep sea? Did it originate in ponds on the Earth's surface? Or was it brought to our planet from somewhere out in the cosmos? These are the Mysteries of Life, a series that aims to explore various interesting topics to do with life and our existence, from the start to the end of life.

Nursed by warm sun beams in primeval caves,
organic life began beneath the waves.
Hence, without parent, by spontaneous birth,
rise the first specks of animated Earth.

First uploaded video since i subscribed. Cant wait for the continuation of the series. So far the videos i've watched have all motivated my imagination and love of the subject matters.

Earlier on, volcanic ponds may have been present, where water collected around volcanic vents that were much closer to the surface. This is where there are vents, water, sunlight and all things necessary for abiogenesis.

Excellent show. Is there any evidence or thoughts on multiple origins of life. Surely, as many "little warm ponds" as there were, life must have started more than once. Life starting in a single pond might mean the chance of life is astronomically small. Survival would have been even more improbable.

Your ability to synthesize the vast research on biological origins and clearly summarize it for us is astounding! Thanks so much for sharing your insights with us!

This is like a really deep version of the classic "what came first, chicken or egg?"

Not all hydrothermal vents exist under the oceans. East African Rift has many of them in the Afar Triangle, and many exist along the fault lines that run along the west coast of North America on land. Mono Lake comes to mind. All of these are at the surface or just below in shallow lakes. Also back 4 billion years ago the spin of the Earth was faster and the Moon was closer to theEarth so the Earth's day was 6 hours long and high and low tides reaching hundreds of feet high and covered many miles inland for a tidal area, high tide occurring every three hours. That too would allow for dry periods for life's requirements of dry periods and exposure to UV light. One must not forget the environment in which life evolved back then. To assume it has always been like it is today, is a great mistake.

wet-drying-dry-wetting-wet just seems like a much more powerful polymerization pump than always wet. also, as mentioned, also encompasses hydrophobic interactions.

Nearly at 1k subs :) Fantastic video btw.

Life indeed is wonderful and precious. Maybe in stead of searching for how it began we should start to appreciate it and learn to take care of our beautiful Earth full of living beings.

A couple of top-of-the-head comments, both hydrothermal vent related,

1. Why restrict "lack of experimental data" to the lab? Is there no evidence for such chemistry in existing and/or older vents?

2. Warm pools are likely more consistent and widespread, but why exclude the possibility of tides creating the right kinds of cyclic conditions over hydrothermal vents for suitable chemistry? What kind of reaction timescale are we talking about, anyway?

[RealityAlwaysWins]

It was just the right combination of proteins, chemicals and environment that created life, but keep in mind it took millions of years to grow and develop.

Obviously Life was intelligently designed by our Lord and Saviour the Flying Spaghetti Monster

i just find your channel, , , , you are doing a really good job
my only advice is that you need to dive more in depth and instead of making one video talking about the arginine of life (or any subject ) make it five or ten videos. it means more for work. but if you want your channel to success you must give more information ... not just an overall view

that been said .. i really enjoy this video thanks ^_^

[captainstroon]

The panspermia theory doesn't answer the question of how life began. It just states how already existing life arrived on earth.
It's if I would explain where money comes from by telling you how I earned it. Maybe true and interesting but not answering the question.

I think regular sand might be a decent environment for biogenesis. Maybe a millimeter deep on a wet, sunny beach. Or maybe fresh water. Just an amateur's hunch.

A new book published by Austin Macauley Publishers titled From Chemistry to Life on Earth outlines abiogenesis in great detail with a solution to the evolution of the genetic code and the ribosome as well as the cell in general using 290 references, 50 illustrations and several information tables with a proposed molecular natural selection formula and a worked example for ATP.

4:21 I've read the aforementioned paper, but still I'm not a fan of RNA world hypothesis. One glaring fault of this hypothesis is neglected by everyone. A smaller RNA can replicate faster than a larger one. So, in an RNA world, only small(~200nt) RNAs will survive. I don't know, how this little no. of nucleotides can evolve to genes necessary for protein synthesis and maybe, acquire a plasma membrane.

No one really knows how life was made, life is STILL a mystery!!
