Goes to show that skin color shouldn't be an indicator of "superiority" or "inferiority," it just represents how we humans have adapted to different biomes.

[@raydavison4288]

Thank you for making the subject of human evolution simple enough for this old man to understand. 😊

[@kobrateeth4673]

I’m an anthropology minor in college- this is an amazing introduction to human evolution

[@briobarb8525]

Love your intelligent but light-hearted approach and presentation. Thank you. Look forward to more! 😊

[@GlorifiedTruth]

Agreed, Dr. Sammy does a great job.

[@sqrt2295]

0:46 Very suspicious looking cave paintings...

[@sparkle5318]

[@user-wh8fb8mw4s]

i love evolution

[@wotsup9oo]

The way you explain things are simple, but the actual content is very sophisticated. Great.

[@quorrexnoway9127]

Nice video! :) 11:16 Wasn't there the coincidence, that all other human subspecies vanished once homo sapiens started to settle near them? Like it strongly indicated that the thing they did not survive were homo sapiens? Not to be prejudgment against our own species but.... *gestures wildly at everything*

[@hollyhobgoblin8838]

This episode was so good! I love learning about early hominids, and the Thought Bubble renditions of early hominid species were just precious.

[@truejim]

It’s fun to ponder that once upon a time Middle Earth (mediterranean) really was populated by multiple human-like species.

[@Beryllahawk]

This was a good one. I came across an old issue of Nat Geo recently (from 2017) discussing how race has nothing to do with genetics and everything to do with social constructs. A lot of the info there on things like melanin and migration was presented here, but the details are better refined now, and it's both interesting and really just NICE to see that we're still learning - and still going in the right direction for a more inclusive understanding of humans.

[@Rubyshadows]

I'm loving this course so far! Dr. Samuel has 100% Reading Rainbow Llevar Burton vibe. ❤️

[@sophiekook1699]

i was just explaining this to my friends the other day and didn’t have any resources to point to (aside from what i remembered in class) !! thank u !!

[@INSPIRITM]

I absolutely loooove your presentation Dr. Sammy! Such a good host for this series. I wish my biology teacher had been like this back in school. I love that I get to reclaim my interest in learning with crash course that school kinda stole from me.

[@AngryKid55]

we can't even get along among different skin colors and ethnicities 😢 i can't even imagine what having more than 1 (sub)species would be like

[@KelseyWolf]

❤ 🎉 fantastic episode and can’t wait for the next!!!

[@imghoti]

I just stumbled onto this channel. It's my new favorite!

[@JC-ji1hp]

So many things about science I swear I have thought about on some level but have never articulated or done some sort of study on. I truly believe their is a deeper understanding within us all we just need to tap in.

[@robabiera733]

This caught me by surprise. Somehow I wasn't really expecting such a deft summation of the latest findings. Or such an engaging presenter. There are some nits I could pick but overall I'd have to say this was pretty awesome! I also have to recognize that I'm already pretty familiar with this subject and I have to wonder what somebody who is new to all this would make of it. Hmmm . . .

[@Terminally_rizible]

I found a mental floss video nine years ago hosted by Hank Green that brought me to Crash Course. I have been enjoying infotainment like this ever since. Thank you, PBS studios for keeping it going.

[@fkhan2006]

this would've been so useful when I took high school biology! Great video!

[@mattsteve7229]

Some of them even learned to control fire they were called fire benders. And the world was never the same.

[@dariann1661]

Love this video and love the host!! More of him please !!

[@AnasSchoolAccount-gh3fl]

This helped me with my school project ty!

[@fayehyuga5259]

I ALWAYS wondered how different coloured people evolved, THAT makes SOOOO much sense. Thanks dude. 😊

[@FranBunnyFFXII]

I'm loving these Anthropology episodes on CC. I studied Bio Anthro for years, but wasnt able to get agree. These are nice to keep up with where I left off. And the host, he got flair! Thanks for teaching us Dr.Sammy!(Did I spell that correctly?)

[@AmandolinJay]

Loved the mohawked Hank icon for humans! :)

[@NguyenHuynh-wv7jt]

Bro also cured my Hippopotomonstrosesquipedaliophobia (fear of long words) problem

[@martyes9563]

Can't wait to see what's next coming from that last one!!

[@charchar456]

Great episode! I love Dr. Sammy's shirt, the embroidery is really cool

[@simonmcglary]

When I first learnt about Denisovian in Asia, and having learnt before about Neanderthal and Homo Sapian it brought to mind the complexity of the reality of the situation. Evolution helps to understand ourselves as well as other species shared traits with us. Evolution is absolutely fascinating, as is nature in general.

[@kaylee8451]

This video cleared up soooo many questions I had about our hominid relatives that didn’t survive. Thank youuuuuuu ❤❤❤🎉🎉🎉

[@andrewroos9583]

Loved this, the presentation style was excellent, great for all ages, fun to watch, engaging

[@dylansearcy3966]

8:44 breath of the wild/tears of the kingdom

[@theboldandthebeautiful3729]

Great episode

[@Soyrubes]

Loved the animations and storytelling!

[@user-sd3mt1rg3f]

AWESOME VIDEO THIS IS SO SO IMPORTANT TO KNOW ALL ON EARTH

[@drewdavis1962]

Fantastic video! Thanks for sharing.

[@joshuateubanks4302]

I m going to listen to this every morning until I can recite it. Thank you.

[@Roboheart1119]

Great video and awesomely researched

[@jasminwoods7758]

this is amazing!!

[@ArleneDKatz]

So well done! Thank you! 🙏🏻. AMNH NYC

[@skybluskyblueify]

There is no beating the wardrobe for this series. I can barely pay attention to the content with how spiffy the host's clothing looks. Great series!

[@OBTX91]

Wow, that was great! I've been looking for a good video for my kid about human evolution and Inthink I've found it

[@gailaltschwager7377]

Thank you!

[@colormegrumpy]

Love Love Dr. Sammy!

[@Darkbox11]

I got chills when you speak about the dogs human relationship ✨👣🐾

[@sarahleonard7309]

My brain is too fried to say something clever, but here's a comment to help with the channel analytics.

[@akankshameena5485]

😂 loving it, man who is writing the script. Kudos team CC

[@Syco108]

Hey y'all! I'm learning!

[@Davlavi]

Another great video.

[@davidletarte214]

thanks, maybe you can go more in-depth on specific species/ subspecies at some point..?

[@ronm6585]

Thank you.

[@neilm2794]

Very interesting. I don’t ask the evolutionary question “if we evolved from apes, why are there still apes” but do sometimes ask “why did none of the other ape species evolve as we did”

[@HGrimes]

thank you ❤

[@kab6754]

Didn't know I'd get a philosophy lesson with my science lesson today. But I'm not complaining ❤❤❤

[@pedrostormrage]

3:43 Interesting implication of the _Homo_ _erectus_ migration: we all have African descent 🌍

[@braxtonanderson3870]

Love these videos.

[@HookBeak_66]

I particularly liked the section: They're not sure who initiated the human/K9 bond & our close relationship first, so I'm thinking it was a trial & error process, until the way things are today.

[@twistedoperator4422]

Makes sense.

[@tyronenorth6644]

I remeber watching this 7 years ago

[@nickstacey3066]

That dub at 3:33 is wild lol

[@Troyless]

where did he get that shirt, it's cool

[@FreeXenon]

I seriously like this guy

[@brothermaynardsbrother]

Very nicely done, Doc! You successfully fed us a tasty repast of the latest advancements in human evolutionary research in a succinct, engaging and entertaining manner. I look forward to consuming more of your cognitively satiating content in the future. Merci, Monsieur Hamlet. Qapla'!

[@kasetophono]

You're hilarious

[@yay-cat]

I did not know that sunshine and folate aren’t pals

[@ericfieldman]

I can appreciate the dubious food

[@MubashirullahD]

who wouldnt laugh at Homo Erectus XD

[@kiransubba2308]

😮wow😊

[@LayingInAMeadow]

Exactly

[@samuelzev4076]

This is real anthropology and not what was taught by Ancient Alien theorists that we are descendants of Ancient Aliens 😅

[@classical_apologetics]

from Ethiopia adis abeba 🇪🇹

[@r4ined492]

what is the first human ancestor?

[@nk3582]

In my mid 30s watching these for fun

[@binkbonkbones3402]

Ahhh I've been writing about this what are the odds!?!😅 I call it middle earth and a bunch of tribes represent various stages interact like lord of the rings complete with faufnir, a "dragon" aka feathered winged dinosaur and the gold ring from norse myth Anachronistic, but metaphorical

[@user-pu2ho4ip3d]

One Day at a Time, that's how.

[@WxddlesHimself]

🔥🔥🔥🔥

[@pyeitme508]

Wow

[@fernparales500]

0:46 there’s an impostor among us😅

[@khaos1999]

Lol yeahhhh, I got some Neanderthal in me, apparently a lot more than most 23andme customers

[@hughmanetti1908]

I’m still not sure about some folks ...

[@jackhester5414]

Stoned ape theory...

[@Kinggenton]

this guy is pretty funny

[@grandthanatos]

I thought humans were more closely related to bonobos than they were to chimpanzees.

[@alh2515]

Genuine Question, why is it have to be species evolving into newer versions, Like when life in earth begin how many species were there, and why human didn't exist from the beginning??

[@realbangbang]

[@marsjokes]

Obviously

[@mr.fishmanman]

The Hell is The Thumbnail Bruh

[@Smokedouttasian]

It's depicting the host chill

[@youssefnaim3375]

Only reason ur saying that is cause the last guy is black. You’ve internalized the idea that chimps are associated with blacks. That’s on you. If it was white guy, you wouldn’t be saying anything. Funny though

[@TheGrifhinx]

It's the host, you new here?

[@The_PsychPlanet]

🥸🥸🥸

[@donaldham308]

6:23 well. By that definition, a donkey would be nearly the same species if only a mule wasn’t sterile.

[@dddddddddddddddf]

Lol

[@JSNY1125]

I wonder if there were any NeTRANSderthals?

[@a40o72]

This is an opportunity by the thumbnail designer to avenge historical wrongs, as blck hominids were usually put before human white Europeans. You can see designer's pattern of correct perceived historical wrongs and social reparations in the other thumbnails in the video list of this channel.

[@karteekchoudhary4837]

1st comment 😂

[@YesmanNoman]

Second :)

[@thatomofolo452]

Yes 😊

[@AmitKumar-bu4tr]

Third

[@quintapion_]

1st always the worst

[@JCM111]

2nd

[@a40o72]

For those asking, the thumbnail tries to prevent perpetuating stereotypes by placing the blck man at the end. usually they aren't, bc the 1st hominids lived in Africa, confusing them with black humans

[@AmandolinJay]

It's just the host?
