The first primates arose around the same time as the dinosaurs went extinct. It is thought that the last common ancestor for all primates existed around 65 million years ago and our order has continued to diverge, producing prosimians, new world monkeys, old world monkeys and apes, which includes humans. In this video, we'll not only explore the species and groups of primates but also look at some of the techniques scientists use to calculate phylogeny including genome sequencing and fossil analysis.

[@caesumcrimson6381]

@@Textbooktravel just some feedback and please know I really like your vids and think you're doing a great job! Just for me in this recent video you detoured twice into a) fossil formation and carbon dating and then b) DNA sequencing. For me I kinda understood why you felt like you had to detour for fossilisation buttt I mean it really took me out of the immersion of the video as it is in fact about primates not fossilisation. By the second detour on DNA sequencing, I was in information overload! I mean most people know these processes already and the ones that don't would have a hard time downloading all the new info - primates taxonomy, fossilisation and carbon dating and then DNA sequencing and chromosomal structures? Yikes It also meant you talked less about the monkeys and apes which is why I clicked the video! In future maybe you could keep those detours for a separate video so you can cover the topic in more detail. Not having a dig at all just offering feedback. Although I really did love your graphics for both sequences so keep that up! All around I enjoyed the video but wanted more information on the primates.

finally! In your dog video you stated that the next video will be about snakes, and it was! Maybe there was a lot of research in your primate video, it had to be delayed. For some reason I'm getting a bit interested in rodents now, because there are literally 2000 of them little critters.

[@Textbooktravel]

Haha! I was hoping you would see this! I think this relatives series is going to take me 20 years to complete!! Rodents are so interesting and I've also been looking at how to break down birds recently too, SO many families and species!! There will be more primate videos to come soon, I decided not to stuff them all into a single video so there will be one video on each of the main groups :)

[@billyr2904]

Ok, also I did see your newest video. The thing about how, with the exception of humans, that apes have the smallest range, well that's foreshadowing humans killing everything (killing everything is just an over exaggeration). In your future ape video, can you explain how humans are foreshadowing the relatives series to why so many mammals (lemurs especially) are threatened.

[@billyr2904]

The cladogram shown in the video is a bit misleading, because there's a myth where evolution is progress, and every step progressively gets better and better till we get to the top, which humans. Now through that idea out of the window, because that's not how it works. You see evolution is about small changes in an organism's genome and doesn't Matter whether it's superior than others (that's called dominion). Humans are just what's called a more derived ape, and the other apes in the superfamily is what's called ancestral (or informally 'primitive'). The order primates itself suggests dominion, because it literally means '1st rank'.

[@agnelomascarenhas8990]

Two items missing was 1)the relationship of primates to the rodents. 2)center of evolution, it would appear that apes first evolved in Asia. Also puzzling was Euarchontaglires evolved in Laurasia, so how did cross over to Africa.

I saw Mtn Gorilla in Virunga in 93 and then in 2017 i saw the Marmoset in the Amazon and was super excited to add the 'smallest' one to my experience. maybe i need to make a list of which i have seen / yet to seen.

There are over eighteen extant families of primates, Lorisidae (Lorises, Pottos, and Angwantibos), Galagidae (Galagos), Lepilemuridae (Sportive Lemurs), Cheirogaleidae (Dwarf Lemurs, Mouse Lemurs, and Fork-Crowned Lemurs), Daubentoniidae (Aye-Aye and Fossil Relatives), Indriidae (Indri, Woolly Lemurs, and Sifakas), Lemuridae (Common Lemurs), Tarsiidae (Tarsiers), Aotidae (Owl Monkeys), Challitrichidae (Marmosets and Tamarins), Pitheciidae (Sakis, Uakaris, and Titis), Atelidae (Spider Monkeys, Howler Monkeys, and Woolly Monkeys), Cebidae (Capuchins and Squirrel Monkeys), Cercopithecidae (Swamp Monkeys), Colobidae (Colobuses, Langurs, Snub-Nosed Monkeys, and Proboscis Monkey), Papionidae (Baboons, Mangabeys, and Macaques), Hylobatidae (Lesser Apes), and Hominidae (Great Apes).

[@billyr2904]

there is actually only one family of old world monkeys (Cercopithecidae). and not 3

[@indyreno2933]

Actually, old world monkeys are a polytypic superfamily (Cercopithecoidea) with three extant families, Cercopithecidae (Swamp Monkeys (contains 6 genera: Allenopithecus, Miopithecus, Erythrocebus, Chlorocebus, Allochrocebus, and Cercopithecus)), Colobidae (Colobuses, Langurs, Snub-Nosed Monkeys, and Proboscis Monkey (contains 10 genera: Procolobus, Colobus, Piliocolobus, Simias, Pygathrix, Presbytis, Trachypithecus, Semnopithecus, Rhinopithecus, and Nasalis)), and Papionidae (Baboons, Mangabeys, and Macaques (contains 15 genera: Macaca, Pithecoleo, Oreopithecus, Cynomolgus, Calidopithecus, Indocebus, Hyocaudus, Leucocebus, Melanocebus, Rungwecebus, Lophocebus, Cercocebus, Theropithecus, Mandrillus, and Papio)), that makes ten families of anthropoids, Catarrhini (Apes and Old World Monkeys) contains two superfamilies, Cercopithecoidea (Old World Monkeys (contains 3 families: Cercopithecidae, Colobidae, and Papionidae)) and Hominoidea (Apes (contains 2 families: Hylobatidae and Hominidae)), while Platyrrhini (New World Monkeys) contains two superfamilies, Callithricoidea (Lesser New World Monkeys (contains 2 families: Aotidae and Callithrichidae)) and Ceboidea (Great New World Monkeys (contains 3 families: Pitheciidae, Atelidae, and Cebidae)).

I disagree because according to wikipedia colobidae and papionidae, don't exist, even when I type them in on Google they don't exist, and for colobidae when I type it in it says "do you mean columbidae?"

These are very fascinating things we don’t usually hear about but are what constitute the fundamental physiological differences of various primates from other primates and other mammals, not to mention the obvious reduction in jaw length, increase in cranial volume and the shifts in diet.

Here's a new idea. What if the earliest hominids (say 4, 5, maybe 10 million years ago) were all bipedal all along from Day 1? But we were so violent and deadly due to our bipedalness allowing for handheld weapons to be swung with greater force, we drove all the other primate groups of great apes' ancestry up into the trees for protection where they developed hands and feet for climbing. It's difficult to climb a tree and carry a rock at the same time and we're still working on improving the solutions to that problem to this day. Hominins didnt come down from the trees, we drove the hominids up into the trees.

Fun story - when I went to the zoo few years ago, I stopped by chimpanzee area to watch them. Some of them were napping while others were monkeying around. But what caught my eye was one chimp who was sitting on the rock and was doing something that looked like he was counting on his fingers. Then, all of a sudden, he stopped and threw his hands in the air and started "counting" again. He kept repeating the same process for a while until he accidentally smacked himself in a face with his hand and then he just gave up.
