- Now that we have some background information out of the way, we can really dig into the good stuff. Anthropology is concerned with the order Primates, so where did this order come from? What is the origin of primates? When did they emerge, and what did they first look like? This is a complicated question, but this is where we have to begin our journey, so let's take a look at what we know so far!

I know the comment section has a big chance of being on fire in the next few days with all crazy stuff coming from creationists.
I can't wait to check this out in a few hours/day.
See you guys then.
I'll keep you informed
Creationists show up at evolution videos like ants show up at picnics.
Hey, I am a muslim, Islam has thousands of evidences and proofs for it validity and it authenticity, search on CZcams about : The Last Prophet - More than 1000 Evidences for the Validity of Islam - Full Video/Audiobook w/text by Dr. Haitham Talaat , this book also is a book in tge atheism criticism.
They struck my temples with a socket wrench in battle,be cautious!
Came for the creationists, stayed for the science.

Literally my experience lmfao
I’m an undergraduate anthropology student and I’m working on an honors thesis that takes a critical look at the current taxonomic placement of species within Hominidae, basically asking the question are we using human exceptionalism to artificially push back our last common ancestor with chimpanzees further than what the molecular clock suggests in order to refrain from adding them to our genus Homo? Adding the two members of Pan to genus Homo has been proposed since 2001 by the late Dr. Goodman, which him and his team were responsible for making Ponglidae obsolete and adding all great apes to the family Hominidae as well as condensing gorillas into the subfamily Homininae and Pan and Homo into the tribe Hominini. I primarily take a critical approach utilizing a mixed-methods methodology using a systematic literature review while also critiquing the colloquial terms used in the articles noting when the term “ape” or “great ape” is used to either include or exclude humans. So I find videos like this one fascinating and informative.
That’s a super cool thesis and I want to know more about this
Same as my predecessor said, curious to hear/ read more
@@noahdelo I’m buried in research as it’s a lot to go into, but I have presented the introduction at an honors conference where I briefly covered the history of pithecophobia in academia and western society with political figures in America today rejecting evolution and our relationship to other apes. Then I explored the genetic and morphological similarities between Homo and Pan and mentioned how the current accepted theory of our last common ancestor with chimpanzees was a knuckle walker. I pointed out how the hip bone of Australopithecus and Ardipithecus are intermediate between humans and chimpanzees, and despite all findings of long armed fossil hominids said to be transitional between a knuckle walking apes and humans lacked the wrist bone necessary for knuckle walking. I pointed out how the similarities between us and orangutans imply a more basal common ancestor while chimps and gorillas are more derived fitting into their niches. I also pointed out that despite the molecular clock estimating a 4-6 million year split between us and chimpanzees, most researchers use the lack of ape fossils in the Miocene and the assumption of a knuckle walking ancestor to date the last common ancestor approximately 7-8 million years ago. Even know the genetic evidence shows were more closely related to chimpanzees than what lions are to tigers (according to identical base pairs) estimating about 3-5 million years split comparatively and still grouped together in the same genus. Then I challenged the concept of using the tradition use of the word “ape” being 1) being polyphyletic and scientifically inaccurate and 2) if the Felidae family is the cat family, and the Equidae family is the horse family, then the Hominidae is the human family consisting of eight extant species of humans. There’s a lot more involved with complex topics of ape hybridization and great ape personhood that also was covered in the discussion after that I can go more into later.
I remember this being a point in Sir Terry Pratchett's "The science of Discworld" which he co-authored with two science writers.
Except that they didn't elevate chimpansees to Homo genus, they downgraded humans to the Pan genus, calling humans Pan Narrans, the storytelling ape rather than "wise man". One can see where they were coming from.
@@frankpulmanns6685 I’ve read the same. I would agree however because of the rules of taxonomy the oldest name gets priority and Homo is older than Pan since Linnaeus grouped all Catarrhines from chimpanzees to vervet monkeys in genus Homo with humans.
thank you Dave and Erika!
I'm subbed to Erika too. Two-hour long discussions and explanation of scientific papers, I love it.

Exactly what i learned a year ago in my biology class. This is a nice refresher.
Yippee! This was partially covered in my Human Biology course earlier this semester! I've already done the exam for that part of the course but it's always nice to revisit this.
Thanks for this series, Prof Dave
fantastic video, I love digestible and informative videos about phylogeny and evolution like this!
Hey Prof Dave, I recently bought your book (Is My Wifi Organic?) and I'm currently reading it. It's really good and informative! I only learned about it from a youtube comment, but I do see you have it linked at the bottom of the vid description. My humble recommendation is maybe have a couple secs of your vids making more people aware of it? The book does people a great service in science literacy and they should buy/read it! Thx!
I watched your popular debates and laughed a lot thanks for that. I don’t get half of debate about life beginning but it was also fun. Great job man congrats.
Hey professor dave! Wondering if you'd ever do a more detailed explanation of general relativity, I watched the modern physics playlist and while the quantum mechanics was great, the GR felt a bit unexplained
it's on the list! just need a good writer
TEACHER , I love you ❤
Everything that I need are here in your channel ❤
I've never clicked faster in my life
Great summary.
Yaaaaas! Monkey time!!!!
It's always so fun learning about these origins and anthropology dodads. I hope Dave goes up to and over Genus Homo, too. It's still really amazing and confusing how there got to be so many human-like critters but then we Homo Sapiens are the only ones what stuck.
i've been waiting a while to ask this but are you going to continue the geology playlist? i loved looking forward to seeing new videos come from it, especially since im starting a geology degree in fall this year 🤩
Good degree!
I’m done with geology for now
@@ProfessorDaveExplains:( alright, that's fine, still great to have it
I knew most of this in general, but the early evolution of primates/pseudo-primates was all new to me!
this is great!
Another collab with GG? Awesome.
Nice video as always
Also, "Purgatorius" is a really badass name for such a tiny animal lol
I love how everyone unanimously clicked the video to look for creationists in the comments but instead found themselves enjoying the video as well.

Love that colour gradient metaphor. I like to tell people to try to imagine 500,000 pictures of individuals down a hallway with a chimp at one end and a person at the other. Now make the necessary changes from picture to picture to make the chimp face morph to a person face incrementally. Would you be able to tell the difference from one person to the person immediately next to them since they have only changed 1/500,000th what about 2 over? What about 200 over? Now I tell them 200 over is the difference between them and someone who built the great pyramids. Just 499800 generations to go. Then I explain that our common ancestor with chimps wasn't a chimp actually and that the chimp is just a place marker for the thought experiment. My methodology is also loose and based on an estimated average of 20 years between generations from our LCA with chimps to now but it works for a thought experiment.
Oh boy the creationist are gonna have a field day with this one
Get ready to read recent comments, it's about to get fun!
More of the usual sneers & snarls, attempted gotcha questions, biblical quotes and, of course, displays of basic ignorance. They play the game so predictably.
How goes the hunt?
Extremely interesting stuff
Hey, Dave. Did you see the Netflix special about the evolution of life? I thought it was good, but I'm glad you went into more detail about primates.
Netflix is shitballs.
When I think about the formation of life on Earth, and I picture the Hadean, and Archean, lending their energy to the simmering rise in complexities, in the warm waters of the Proterozoic, I imagine the energy that must have been absorbed into so many, countless chemical reactions. Electrons zipping from one orbit, to the next. I can't help but to see a similarity, between the explosion of new life, at the Cambrian, and crystals falling out of saturated solution.
I think I made a Creationists head explode the other day when I kept calling him a hominid. We're literally IN the ape family tree, and he just couldn't handle it. LMAO!
I remember years ago a creationist idiot kept writing comments calling atheists "super monkey"s, thinking himself so clever in how he mocked us. Of course, he just kept exposing himself as a religious moron.
Almost like they don't understand that hominid comes from homo.
Ofc, then they'd probably be outraged that you're calling them gay. 🤦🏻
Did you tell the creationist that a Christian (Linneaus) was the first to identify humans as apes in a classification system?
Purgatorius sounds like an animal that got stuck between others.
I have human evolution this year it helps a lot ..... Thanks ....

A bit dated "Prof". Eukaryotes from a fusion of Archaea and Bacteria, and endosymbiosis of another bacterium to form the plants. LUCA could not have eukaryotic then, as depicted with a nucleus and ER.
Look for accelerated speciation during times of rapid environmental change. Thus morphologically similar but genetically divergent parent & daughter species can be distinguished as pre vs post some volcanic eruption or ice age or, if our retroviruses can tell the tale, a disease epidemic.
hooray new video
I do wonder about the evolution of primate vision compared to other mammals. Our ancestors were probably the few who came out during the day during the Mesozoic.

Hello

Best definition for "primate" I've found so far:
“Primates” are collectively defined as any gill-less, organic RNA/DNA protein-based, metabolic, metazoic, nucleic, diploid, bilaterally-symmetrical, endothermic, digestive, tryploblast, opisthokont, deuterostome coelemate with a spinal chord and 12 cranial nerves connecting to a limbic system in an enlarged cerebrial cortex with a reduced olfactory region inside a jawed-skull with specialized teeth including canines and premolars, forward-oriented fully-enclosed optical orbits, and a single temporal fenestra, -attached to a vertebrate hind-leg dominant tetrapoidal skeleton with a sacral pelvis, clavical, and wrist & ankle bones; and having lungs, tear ducts, body-wide hair follicles, lactal mammaries, opposable thumbs, and keratinized dermis with chitinous nails on all five digits on all four extremities, in addition to an embryonic development in amniotic fluid, leading to a placental birth and highly social lifestyle.

Trying to take down similarities between myself and Purgatorius😅
American Journal of Human Evolution
4 December 2018
"More than a decade of DNA barcoding encompassing about five million specimens covering 100,000 animal species supports the generalization that mitochondrial DNA clusters largely overlap with species as defined by domain experts. Almost all animal species have arrived at a similar result consequent to a similar process of expansion from mitochondrial uniformity within the last one to several hundred thousand years.”
Convergent evolution.
My cat was sitting on my lap and at 3:35 when Purgatorius came up she stood up faced the screen and watched. At 4:00 she reached over my keyboard and touched the screen. Apparently cats would like to meet Purgatorius .... it's an evolution thing.

Science isn’t inherently dogmatic, but scientists can be.
Be scientific in your critique. Give 3 examples of scientists being dogmatic.
@@AlbertaGeek I’ll give you five:
1. In faradays 1844 letter to richard taylor, faraday speaks on the atomic doctrine, he suggests that atomic models are just frameworks to understand phenomena with matter. He says that the atomic doctrine is only a hypothesis that is separate from the facts, the facts being definite proportions, prime numbers, &c. Faraday says that a common mistake people make, students especially, is that they assume the hypothesis true based on these facts of phenomena. He then goes on to show how John Daltons atomic model doesn’t account for conductivity and insulation.
2. two quotes from albert Einstein that when taken together show a dogmatic cling heliocentrism because his theory of gravity cannot prove geocentrism or heliocentrism because it is relative to any select point (you could even make a cosmological model where our moon is the center lol).
“TO THE QUESTION WHETHER OR NOT THE MOTION OF THE EARTH IN SPACE CAN BE MADE PERCEPTIBLE IN TERRESTRIAL EXPERIMENTS. WE HAVE ALREADY REMARKED IN SECTION V THAT ALL ATTEMPTS OF THIS NATURE LED TO A NEGATIVE RESULT. BEFORE THE THEORY OF RELATIVITY WAS PUT FORWARD, IT WAS DIFFICULT TO BECOME RECONCILED TO THIS NEGATIVE RESULT..."
"THE PROBLEM WHICH NOW FACED
EINSTEIN SCIENCE MAS CONSIDERABLE. FOR THERE SEEMED TO BE ONLY THREE ALTERNATIVES. THE FIRST WAS THAT THE EARTH WAS STANDING STILL, WHICH MEANT SCUTTLING THE WHOLE COPERNICAN THEORY AND WAS UNTHINKABLE."
3. The idea that the speed of light is a constant is dogmatic because the empirical data shows otherwise. MMX in the later years of observations showed that the “speed” of light changes in relation to moon cycles and motion of the sun relative to earth. The unit of measurement, the meter, was actually changed to adhere to the AVERAGE speed of light.
4. The dogmatic approach of modern medicine that models the body as purely mechanical and that we are complex organic automata. This and also the claim that the mind is entirely contained within our skulls, that the mind is physical. These dogmas are perpetuated by people who are “physicians” in the classical sense of the word. This belief makes mechanical medicine the only viable kind of medicine.
5. I’m just going to shoot off a few more short ones:
That laws of nature are fixed.
That nature is purposeless.
That Matter is unconscious.
The total amount of matter and energy is fixed.
Biological hereditary is material.
I made a reply but i think it got taken down or yt flagged it, can you see it?
In faradays paper to richard taylor 1844 he introduces the phenomena of conductivity and insulation to John Daltons atomic model showing how the void between daltons atoms is conducting and insulating which is illogical. He then points towards Boscovich’s theory of atoms which is based off mathematical points that have force properties. Faraday writes that a common mistake for those studying atomic doctrine is that they take the hypothesis, that matter is comprised of atoms, to be true based on the facts they observe suchas definite proportions, prime numbers, &c. Faraday claims that the hypothesis cannot be assumed true based off of these facts. Faraday suggests in this letter that the hypothesis of atoms is merely a way to account for the mathematical facts derived from phenomena.
Einsteinian special relativity claims that any point in the universe can be the center of motion yet Einstein says "THE PROBLEM WHICH NOW FACED
SCIENCE WAS CONSIDERABLE. FOR THERE SEEMED TO BE ONLY THREE ALTERNATIVES. THE FIRST WAS THAT THE EARTH WAS STANDING STILL, WHICH MEANT SCUTTLING THE WHOLE COPERNICAN THEORY AND WAS UNTHINKABLE."
If you want to get a better understanding of empiricism and dogmatism i would recommend ch.2 bk.2 of Kants Critique of Pure Reason.
a few more dogmas of science:
That matter is unconscious
That nature is mechanical
That the laws of nature are fixed
That memories are stored in your brain
That your mind is in your head
That biological hereditary is material
That mechanistic medicine is the only kind that works
That nature is purposeless
That the total amount of matter and energy in the universe is fixed
All of these are dogmatic claims that makeup the principles of thinking for many scientists today.
@@deed18 You clearly do not know what "dogmatic" means. Literally nothing in your reply supports the assertion you made in your OP.
And how did they evolve? 😂
