Precambrian Earth and Life History The Hadean and Archean - Part 1

[@SamtheIrishexan]

I just want to say thank you for uploading all of this on KZbin. I am in debt up to my eye balls after going to college for finance, but would have rather taken more sciences if I could go back and go into debt for something I would actually enjoy. This is like a free course it's excellent.

[@tomlavelle8518]

I know nothing about geology. These are wonderful lectures in which to learn!

[@JMDinOKC]

It's about rocks.

[@gerrardjones28]

@@JMDinOKC well it depends what type your doing but even a thing as simple as rocks can be interesting to some people, i personally love learning this stuff, if only school was like this

[@walkerpierce5446]

I really want to watch/listen to a lecture like this on the meticulous development of life.

[@trexxg1436]

Great Documentary thank you enjoyed learning about the early Earth.

[@vexiii7102]

It's 12 am, I have never been interested in this topic yet I am so engaged in listening about it for some reason, thank you!

[@SueFerreira75]

Thank you, Dr Chris White. I am very grateful for all the work you have put into this extensive, excellent basic course on Geology. You have help me clarify the time and space sequencing of the past life of our planet.

[@RafaelSCalsaverini]

Dude, I just found your channel completely randomly and I'm in love with it. Thanks for putting so much effort in putting free, quality content here.

[@GreySectoid]

These stimulate my imagination greatly, thank you doctor.

[@mdhbigdog]

Very good and clear explanations of complicated matters. Thank you!

[@mrtoastyman07]

Im sharing this playlist everywhere - it is top teir info and very well done. I would love love love you to update this series with the latest research and go into even more detail, just so interesting - thanks you!

[@SajoGotoru]

Ga in these slides stands for Giga Annum, if anyone was wondering. It means a billion years. 1 Ga = 1 Billion years

[@MemeMaradith]

These are great! I love documentaries but they tend to burry the timelines under theatrics. Thank you for making these comprehensive lectures

[@charlotte-mg9wj]

I love documentaries to but if you are hard of hearing like me those theatrics and "background" music can ruin it. It's refreshing to be able to watch something without subtitles for a change.

[@MemeMaradith]

@@charlotte-mg9wj that's a good point. I hadn't even considered that.

[@itzelpretzel]

So interesting.. It makes my imagination run wild!! I could probably use a primer on the basics of geology though

[@gerrardjones28]

A nice suprise, thank you once again for these lectures!

[@JameBlack]

Lol, I thought I'm the only one watching this

[@gerrardjones28]

Yeah lol, its so undrated!

[@ellenbryn]

Holodno Bez Tebe - Look at how many subscribers there are. I don't think we're the only ones :-)

[@ellenbryn]

Dr. White - Thanks from all of us rando occasional online "auditors." You need a Ko-fi lik or something so we can show our support. ;)

[@mcshach9982]

The best stuff on prehistory out there! Thanks for letting us comment, i tried on the videos you made 2 years ago when i found these geology lessons but there wasnt an option.

[@LDrosophila]

Thank you for this content

[@historicalgeologywithdr.ch9083]

My pleasure, thank you for watching.

[@nobody8328]

"Remember this diagram, as it has a tendency to pop up on exams" Im 51, but i still had a lil moment of pure panic! 😂

[@pratyushkumardash4410]

Thank you so much for all the knowledge. I am too grateful for all your lectures about precambrian, proterozoic, mesozoic and cenozoic times...

[@roykay4709]

Love this channel. Is there any way to make a modest contribution to the cause?

[@mentally_infirm]

rock chemistry. 😊 perfect playlist for sleep

[@nicholasmaude6906]

Wouldn't the Hadean atmosphere also include methane?

[@eoachan9304]

What about the Room Problem for granitic intrusions? Any solutions?

[@clarkharney8805]

Thanks for the information in these lectures! I like how you did the Zoics (3) and the Precambrian separately.

[@Mayo-Lord]

Just discovered the channel. Out with a back injury, ep 1 here we go lol!

[@SamtheIrishexan]

If we could revive the bacteria or whatever that led to the great oxygenation to Mars or even bioengineer other colife forms and spread them on high co2 worlds.

Precambrian life topic explain from paleobotany 🙏

[@satanofficial3902]

Little nothing-in-particular thingies would eventually turn into plant-like thingies and eventually turn into lovely turnips. (This comment has the Baldrick seal-of-approval.)

[@satanofficial3902]

Luckily, those plant-like thingies didn't turn into... triffids... Or not so far, anyway.

[@satanofficial3902]

Fact checkers say..."True!"

[@gerrardjones28]

What?

[@satanofficial3902]

Very nice lecture. Quite nice indeed. About the only thing i could possibly get nit-picky about is the mispronunciation of the word "Uranus".

[@eoachan9304]

New research has shown that multicellular very small life appeared 1.2 billon years ago :) There are also indications that life probably got going around 4 to 4.3 billion years ago. You skipped over the Theia-earth mk 1 collision? Recent research proves that there indeed was a crust 4.4 billion years ago based on the Australian zircon inclusions as you mentioned, most amazing,plus the Acasta gneiss is 4.03 billion years old, and the Nuvvuagittuq greenstone belt in Quebec is 4.28 billion years old. Most definitely these oldest rocks are rare! Do you agree with some ideas that the 1st granite may have been formed from asteroid impact melts? Also, you 1st say that water would be rare to absent on Hadean earth, but then you say common volcanism would have released water vapour alongside other gasses. does that not imply more water was present earlier, esp in line with the Jack Hill zircon research? Do you agree with some research which suggests Archean earth was mostly basaltic crust with many volcanic islands and a few tiny mice continents?

[@fishtank1015]

I didn't know water was watery

I can't pay attention after the dog The real mystery is who's the dog

[@kuntface5]

Stop trying to make Precambrian a thing

Nerd lol
