The Origin of Life on Earth

You must have wondered about it before, haven't you? How did life begin on earth? I mean the very first thing. The first unicellular organism, billions of years ago. Is it even possible? As it happens, our understanding of chemistry, biochemistry, and biology has become so sophisticated over the years, that we now have a pretty reasonable grasp as to how abiogenesis must have occurred. This is the spontaneous generation of life from non-living material. As incredible as it sounds, there is a lot of science to discuss here, so let's get into it!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

This is eye-opening. I always thought an organism was just the thing that she did with a vibrator after you left the room.

For anyone seeing this in the future. About a week ago japanese scientists conclusively proved that the components necessary to form life can be found on meteorites

HS Bio and Physics teacher here. The kids really "get" you. I so appreciate all you do for me and my students' learning

[Plinian]

Your channel has been incredibly helpful both for my university studies and convincing my skeptical father of the validity of evolution. He was really into Stephen Meyer and the Discovery Institute, said stuff like "there's no proof for animals being able to change phylums" even when offered evidence of transitional fossils, and how "we don't see evolution continuing to happen today in any species", so these videos have really helped him be more supportive of the field I want to study. Thanks.

I really like how you speak, very clear. I'm not a native speaker, and i'm enjoying your videos!

[chimchu]

Thanks for making this content, i never went to college, but I've always been fascinated by science. Your videos make these complex subjects fairly easy to digest and learn, even for lay-people.

How about uploading a video about Cryobiology and how certain chemical compounds block ice growth and reduce or eliminate freezing damage? I would very much like to see that.

[johnwilson]

I have seen your 4 videos . I am a science master. I am going to teach heredity and evolution to 10th standard students on Monday. Your explanation skill is very good . animations made the lessons more illustrated. Very good keep it up bro

80% comments : Dumb video! I'm religious so this can't be true
10% comments: Nice video! Thanks!
9% comments : when will you bring out X series?

So there was a study in 2012 where they conclude that hydrothermal pools would be the most suitable environment for proto-life form in based on high ratios of potassium since cells need a ton of potassium to synthesize protein.

I love how simple it is to understand. That is a very useful component, especially for me.

May you prosper, whomever added the Arabic translation.

I watched six prior videos on how life began on Earth. Yours was the last video i watched. You were very straight forward and easy to understand. Plus you spoke slow and easy. I subscribed to your channel. Thank you for teaching me this!!

[canbest]

Love reading the comments from all of the triggered theists

[Roycec]

Hey professor Dave, I'm currently restudying the biology and chemistry I learned while studying biomedical engineering. I really like your videos and explanations. I'd appreciate it if you could make more videos about biology, chemistry and biochemistry, with lots of practice problems, thanks!

[DillyThePickley]

Hey! James Tour supporters! You might want to start studying this instead of putting faith in someone who has not studied enough biology!

[timothyvenable]

I thought the Miller-Urey experiment produced amino acids randomly, both right and left handed, but living organisms only use left handed? So the experiment produced hundreds of ONLY left handed amino acids?

Also I’m always skeptical when a scientist says “it’s not a stretch to assume”… that means they don’t know the answer for sure but it’s only a guess. So I don’t take their word for it unless they have the evidence

[eltonron]

When he proves Tour wrong, he can be famous.
When he creates life, he can be God. When he creates consciousness he can prove he's God.

THANKS FOR LL YOUR EFFORTS TO MAKE THIS UNDERSTANDABLE!!
