Early Genus Homo: Homo habilis and Homo rudolfensis

We've finally arrived at our own genus, Homo! But we aren't talking about human beings yet, there are a number of species in this genus that are now totally extinct, but are important to learn about in order to understand how our species came about. The first two species from Homo that we will look at are Homo habilis and Homo rudolfensis. When did these emerge? What was their morphology? How did they differ from us today? Let's find out!

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

Was going to make a joke about putting a flat earther in the thumbnail haha

Gutsick Gibbon got me into anthropology. I like how you break things down fast and easy.

Areas of London have very similar people living there

Congrats on passing the 3 million subscriber mark, I've been watching your videos for a while now, love the debunks, keep it all coming.

[retrodaze]

Absolutely love your work, brother... Please keep pushing science, logic and reason and please keep pushing back on the unreasonable... Im here for it. And the world needs it...

Probably also worth saying that huge jaw muscles that attach around the skull restrict how large the skull can develop. Moving to foods that require less chewing allows these muscles to reduce in size, and their attachment points to also reduce, enabling the skull to be larger.

Great explanation into how we got the brain structure over time, love this stuff thanks!

Some of the best videos on the site. Thank you

I remember going to the Natural History Museum in DC last year, and we went to the place with all the wax sculptures of proto-humans, and I judged them all based on if I could fight them, or if they would be chill to hang out with.

"Homo Habilis is nothing to write home about...."
I guess I'll have to tell my dad to disregard everything I wrote in the birthday card I sent him.

I want a full playlist of evolutionary biology from this channel. Please

[crow-dont-know]

Just noticed that Gutsick Gibbon wrote the script for this. Where does she find the time!?

[Moist._Robot]

What’s a good book to read on human evolution?

[KeithCooper-Albuquerque]

Thanks for another fascinating video, Professor!

[martinlulak]

This is a great series, thank you professor Dave!!

[TheRedRaccoonDog]

Whoa. Nice Joe Rogan photo for the thumbnail.

[Rio-unjl]

Professor Davecan can you do a video reviewing Dr. Steven Greer's appearance on the PBD podcast?

[michaelcarrig]

Hey Dave, I know this isn't the subject of the video, but I have been going over your Tour videos and I wanted to ask what you think of this guy Dr. Hector Zenil and his "8 Fallacies" blog post. He is certainly not a demagogue and his analysis seems fascinating, though it is entirely focused on Cronin's work with algorithms. I am unclear why he would go onto Tour's channel, given Tour's implicit anti-intellectualism. If you have any insight into his work, I would love to hear your view.

Thanks for the class! May you be well!

i heard some interesting speculation that the increase in brain size was made possible by more efficient heat loss due to our ability to sweat across our entire body.
