History of the Earth Part 4: Phanerozoic Eon – Cenozoic Era

We are almost through the Phanerozoic eon! After the Paleozoic and Mesozoic Eras, we get to the Cenozoic era, which is the one we are still living in today. This is the age of mammals, which came to dominate the Earth, and here we also see the continents begin to approach their current locations. We also begin to see some glacial activity. Let's get a closer look!

The most hype series of 2022. Always love getting these notifications.

When I was a kid in the 60s, I told my teacher that it looked like South America and Africa would fit together. She told me it was just a coincidence.

Dave you're one of my top channels bro....i learn new things EVERYTIME i watch your videos...please keep up the great work you're doing...

One small correction: The dinosaurs did not all die off. The descendants of the avion dinosaurs are still with us and their species outnumber the mammals about 2 to 1. Yes, all the big ones died off, but not all of them. I imagine that the birds survived for the same reason the mammals did. They were small and endothermic. That made it possible for them to survive the impact winter and food shortage that likely lasted for decades.

Great info, Professor Dave. Harkening back to my school days, I recall studying the different epochs, eons, and periods, but we never really explored the impacts of plate tectonics on ocean currents and global climate. In those days, we basically studied the causes of the transition from predominant dinosaur to predominant mammals, and mixed in some info on how early primates evolved into homo sapiens. Always appreciate you taking these scientific wonders and explaining history through story-telling. Kudos once again!

Wait, this all happened before the flood? Just kidding. I am a Catholic but to believe the earth is only 6000 years old is dumb. Love your videos.

[youtubeshortuser]

So glad I can watch this videos. My catholic school doesn't talk about this kind of stuff, so I always need to learn on my own.

[carissaa]

I’m so glad I found this channel! Great videos!

[Arccosyne]

Keep making videos Dave, I dont care how niche they get. The internet needs you!

[dethspud]

I do love these bite sized chunks of science goodness.
Thanks, Dave.

[iexist.imnotjoking]

Great video! Explains it in a way that makes it very easy to understand. I really never have problems with understanding on this channel, and that even though I am a little stupid.

When I was on the Glomar Challenger for DSDP Leg 86, in 1982, we collected marine microfossil data for Project CLIMAP. Going models at the time had the Northern Hemisphere trending toward a cooling and glacial advance. Obviously we've blown that trend in a big way

I just watched the last video of geology, then suddenly this video came I think I'm first

Homo Sapiens Sapiens looking like Gigachad at 1:25, proving that we peaked 300k years ago.

[jamiegallier]

Another amazing series, thank you Professor Dave!

[arandom]

This really helped me from my report in Earth Science since the topic is History of Earth.

[wriothesly]

Thank you ! you make learning so much fun 😄😄😄

[CarinaPrimaBallerina]

It's amazing how much we're capable of finding out about everything ... hooray for science!

[himansagimhani]

This is really helpful for me, because our biology sir taught us about this time line but I couldn't imagine any of them but this vedio really gave me a idea how is it look like...thank you...

[Schizniit]

Love how you included that we're still technically in an ice age. That really drives hime the point that it isn't normal to have global temperatures changing this rapidly. So rapidly that the jet stream is permanently changed for the rest of human existence and will probably end up being partly responsible for our extinction.
