Your Place in the Primate Family Tree

Our new sticker is available here: And check out Tacos of Texas!: Purgatorius, a kind of mammal called a plesiadapiform, might’ve been one of your earliest ancestors. But how did we get from a mouse-sized creature that looked more like a squirrel than a monkey -- to you, a member of Homo sapiens? Thanks to Ceri Thomas for the Purgatorius reconstruction.

sam rizzardi : A really good sequel to this would be "Your chicken's place in the dinosaur family tree"

chegeny : It's great to see the whole family together again.

Steve2323ZX : My place on the primate family tree doesn't matter cause primates don't stay on one branch for long.

Facts in Motion : I hate family reunions.

Cities & Skyscrapers : Proud to be a primate.

Austin Rearick : Considering its controversial status in taxonomic limbo, it's sort of darkly ironic that it's named "Purgatorius."

Mr D : Such a huge family, but never a birthday card... what gives?!

chekeichan : It's hard to fit all of these names on my business card.

J Cortese : I will never understand why religious nuts are bothered by this. It's SO COOL that we're just part of a big interwoven tapestry of living things. This is way more interesting and awe-inspiring.

Mr Tumshie : “Humans are not proud of their ancestors, and rarely invite them round to dinner.” ― Douglas Adams I think this is something we should change. An all primate dinner party might be great fun. Or alternatively it might be a disaster that would make a great YouTube video.

beefteki : I knew it! Planet of the apes is a documentary!

Jetlite : The last time I was this early to a PBS Eons video, it was a RNA world...

Gravijta : "There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." - Charles Darwin, On the Origin of Species One of my favorite quotes

Turmunhk Ganba : Could you please cover the evolution of blood?

The Real Flenuan : "They're basically built-in seat cushions" But this misses the most important part. The reason they're so big, hairless and red is so that they can act as sexual signals. That is why they brighten during mating season and don't attain their appearance until after puberty. The same is true of female human breasts, which are much larger than they need to be just to provide ample milk.

Nolan Westrich : How about an episode on the other human species? I'm disappointed that this episode didn't cover neanderthals, denisovans, hobbits, eldar, etc.

Lethallizard 9 : Im interested in the evolutionary history of angiosperms, the flowering plant. How did plants start reproducing like that?

Schooley Spence : It would be fantastic if you guys could cover the evolution of blood!! Great work

Renzo C. Diaz : This is cool. Having a common ancestor with other animals makes me feel more connected to them. We aren't that different yet unique in our way.

O Deum meum! : 0:45 Add an acorn and two fangs and you got Scrat.

The incarnation of boredom : And yet "ape" is considered an insult...

H K : thank goodness someone explains this taxonomic system; this video is very useful! Can u do a video on interglacial periods

James : Can you do one that shows how we evolved over time to be adapted to eat meat (red or otherwise)?

TheJeffreyJJones : Wow, that was a lot of information to take in but I'm really glad you guys made this video. It helps my understanding of this topic quite a bit to hear explained this way.

Fire Nation Files : I am highly evolved Scrat.

R M : Because of you, I know a little more about me. Well reasoned. Thank you.

damir prado : Hey amazing video!! Could you make a video about gondwanian terrestrial crocodilomorphs? Why they got extinct and it relation with the gondwana breake up?!

Healt Desimal : idk about you, but i consider myself a quite intelligent gibbon

Rodoks42 : Evolution of insects pls

Cannon Ranger : There are some days I wish our ancestors never climbed down from the trees. I wonder, is it too late to climb back up? I love this channel.

MASTO BELGAE : Excellent video ! Could you talk about the evolution of our elephants ?

molly_disulfide : an episode on cladistics perhaps?

Mateus da Silva Simplício : Thank you so much for this channel!! It's my absolutely favorite, especially the videos about human evolution!

Symbioticism : How have lorises evolved to be so cute?? WHY?? THEY ARE SO WONDERFUL!

ChrisAntigen : PLEASE CONTINUE THIS!!! It would be amazing to see where we sit in relation to other mammals. I've done a lot of browsing through Wikipedia to see this but it would be awesome to see it in your videos.

Victoria Langerod : I LOVE THIS CHANNEL

Redline : Thanks for explaining Git branching for us, it is always nice to see people help new developers. Though maybe you should talk about Git merging as well.

Natthone Cole : Totally watched the video before I commented. (who am I kidding, any youtuber that sees a video that just came out will comment before watching) Anyway, I always click these videos. One of the most entertaining science channels out there.

Danny Chew : Oh thank goodness Youtube came back online and first video notification is from PBS Eons. XD XD

KhaanMan66 : More on Permian Reptiles.

Prince O'Humour : *What no Gigantopithecus...* 😞

Alexis Perez : In clase we saw a video where a chimp appeared. When it did I told my friend " hey look your cousin!" And she immediately retorted "he is yours too!!" Lmao:'v

Alienjests A : Why are you saying, ‘you’ and ‘your’ when talking about early human ancestors? (Instead of we’ and ‘our’) What isn’t sci show telling us about the origin of their presenters?

Alexander Freundlich : Hallucigenia ep please! I have so little info about this animal!

John Watson : You can debate all you want about evolution, but if you don't like tacos, I don't even want to talk to you...

Marin Cupples : Why are you using the Linnaean classification system instead of phylogenetic systematics? Seemed like you started going that direction at the beginning of the video

James Boaz : This was a very humbling watch. Thank you.

Bram Augat : Wow. One of your best videos. Thank you

Graeme Sharp : I would really love to see a video about the circulatory system and how it evolved from simple organisms into complex ones like ourselves. Great videos. Keep up the good work.
