- Scientists often use the phrase “anatomically modern humans” to describe the point when our ancient ancestors looked like us. But when did humans become behaviorally modern?

I had no idea hashtagging had such a long history.
Yeah, they used the wrong term. It's called "hatching".
It's an octothorp.
Asking when humans became behaviourally modern feels like the anthropological equivalent of asking when a collection of sand grains becomes a pile of sand...
Oh my goodness! Yes!!! Exactly!!!
May I steal that analogy?

I mean even things like “abstract thought” is just advanced generalisation, which is seen in hundreds of species.

Alright, why? Do you actually have an argument? And please don’t just bring up religion, that’s not a valid counter argument.
Flutes on the other hand were invented shortly after Uncles, so we could give our nieces and nephews gifts that make noise at 3:00 AM
westtech001 yoooooouuu know it, lil buddy!!! remember to practice lots & lots so you’ll be real good next time you see me, okay?
This sound so mo to me, op comment below makes it worse
...."Crosshatch pattern", guys.
Crosshatch tag pattern it is then.
I remember some quote from a lady who claimed she believed one of the first important markers in a peoples advancement was a healed femur. To show that care for another and the ability to collaborate in such a physical manner was essential to the first etchings of a society.
Margaret mead is the one to have said that
When Monoliths taught us we could use bones to break other bones
This was gold and honestly deserves more recognition.

A huge part of 'behaviorally modern' is _learned behavior_, and every bit of that learned behavior had to first be discovered/invented - and probably several different times (and it also took a long time for all that learning to become 'sufficient'). I'm tempted to argue that we had the biology for being 'behaviorally modern' before we crossed the threshold into 'modern behavior'.

You mean we are still living within our ecological means and not causing global climate change? You mean a lot of us are hunting with spears and curved throwing sticks?

The oldest instruments they found were flutes? Idk but i feel like drums wouldve come about first but since it wouldve been made with animal hide i imagine it broke down long before we couldve unearthed them.

I know there's better terminology for this.
hash marks or cross hatching perhaps?
Fascist indoctrination and the double cross patterns ftw

I've been watching Sci Show Psych for some time. I liked their videos. That is why I decided to create my own sci-fi/futurist Channel 👍🙂
Well, first you have to ask "where" and "if": it seems that even now not all can make tools, compose meaningful sentences or be artistic beyond hashtagging
That's the milion dollar questions they are trying to avoid for PC reasons. Men were not created equal. Most of us stand in the shoulders of very few giants.
Well these behaviours are not determined by our genome in most people, but it can and did get learned by the "anathomically identical humans" from 200000 years ago.
Ilya Shmakov, Your comment is so true that most people who read it aren't even going to understand it.
The difference between now and then is the clan didn't go out if it's way to support members who wouldn't contribute to the whole. You either worked and learned to benefit your clan or you died, it's one of the reasons the species survived this long.
@@jamesmerkel1932 Nice trolling.
I seem to recall a documentary I saw over 10 years ago on the bottleneck period of ancient humans around 70,000 years ago. Something that was brought up was that apparently in a cave on the African coast that had been occupied by humans around that same 70,000BP time anthropologists found scratch marks on the cave walls. They theorized that an ancient tribe that lived in the cave was trying to work out the tide cycles so they could hunt and gather seashore life at low tide safely. If that's true then that pushes abstract thinking to around 70,000 years ago.
Yay Sci Show Psych!
very good
+sub
This is a question where you get a different answer depending on what you're looking for although I argue even homo erectus was pretty up there. They were capable of fairly impressive tools, in some evidence even boats, and still looked very little like modern humans. I'd say a very important factor overlooked is just how sociable we were at any given time. That is the core of what really shaped humans and lead us into civilization. Human "domestication" as seen by our skull size shrinking and facial features becoming more adolescent is a good clue as to when, but more importantly the trade of red ocher (beyond it's use) is a good benchmark. It's a very old and physical encapsulation of humans slowly laying out the foundations of what we are today.
I’m confused why you didn’t mention evolutionary psychology at all in this video about human behavior evolving
Thats what I was expecting when I read the title. Very interesting topic.
6:09 the most stock-y of stock videos
As soon as I heard “hashtagging” I came to the comment section.
Hank is the end result of human evolution
Especially muscle hank.
"End"? Aren't we still evolving? At least some of us?
@@youmaycallmeken Scientists assumed Evolution would be a continuous process, but once you become Hank it just quits, and all your offspring will just be Hank from then on. Other people will still evolve to try and get lucky enough to become Hank, too, but so far there is only 1 winner for the big game.
Ok . This was very interesting! Please do one on the evolving nature of societal behavior or whatever you call it when a structured language started affecting us, when we started wearing clothes for decoration instead of for protection, when we decided that rotating a cat over a fire until they died wasn't the coolest block party ever (I don't like cats either but that's too far!) or how social media is affecting our society.
Where do burial rituals (+/- ochre) fit in?
This is a fantastic video. Right on point and well done!
This just made it glaringly obvious to me what a blip humans have been time-wise on the Earth's stage.

Learning within a small group means more authority to the teacher and better communication between the students. The difference between groups were connected with their skills and resources. On some point people have started to share things and the authorities changed. The more there were people the more difference became and it compensated with common problems. Something valuable could be lost forever, but the problem solving united everyone and made people better. Preparing and testing ideas also played a great role to the evolution.
The ancient engravers were trying to create a viral meme
Memes are cognitive viruses. They evolve inside us, suffering some random mutation every now and then and being selected if more successful on transmitting itself
Technically, yes.
Without cheeseburgers, can they ever be called truly "modern?"
Only if they served them with pickles.
There must be a cave painting somewhere with a guy with neolithic glasses and a check shirt standing in front of an audience teaching them how to make things. Archeologists need to see if it has hashtag Hank written in the corner.
“Just a little Time. Just a little something else instead. ...”
"hashtag patterns" I'm crying now.
I would say that a big part of the world still isn't behaviorally modern.
funny how I live in South Africa but never heard of blombos cave 😂😅
Ancient humans be tweeting hard
You might also consider the leap in mutuality and cooperation that go hand in hand with the evolution of the female pelvis. Look for the point in time when women could no longer give birth quickly or alone, but needed the help of the tribe. Labor and delivery would require planning, language, and a certain level of abstract thought about what was going on inside on the part of the assistants.
What about studying when ancient humans were first buried? I would imagine the process of burying to indicate some level of abstract thought.
agreed
homo naledi, first discovered in south africa in 2013. It's 335,000-236,000 YA. The cave has been geologically stable for millions of years, and the bodies would have had to have been placed there purposefully to get there. The 'homo' title was debated for a long time because the features of the speciens seemed so primative, however the date turned out to be much more recent than initially projected. And yes, ceremonial burial is was considered a uniquely modern trait of humans. But our evolution and deep past is a very messy field and constantly in flux. I've followed it almost all my life, and the one thing I can say for certain, is that it makes it facinating to watch the sceintific method unfold in real time.
Nope dead bodies stink , bad , fast , ugly stink , no mistake they burry 6 feet down , and did you ever dig ,digging sucks . Bring water and liqire and food , it's hard long and exhausting.
I'm pretty much convinced that the big shift happened for us about 75,000 years ago, when Mt. Toba erupted and the global sapiens population dropped to 10,000 individuals, maybe even lower. I think that event would have really sharpened our cognitive abilities as well as shaped us genetically. Of course, there are those who disagree with this theory, but they have yet to convince me it's wrong.

I have heard a poem written on a cup in Crete was the first recorded evidence of common literacy

We were just vibing and memeing 50 k years ago
Other scientists have said that one of the defining features of behavioral evolution is societies helping their ill folks. From this perspective, America's failed response to COVID-19 represents pre-modern behavior.
40-50ka is about as far as carbon dating can be used accurately. Whenever I hear 40-50ka, I think "at least 40-50ka, possible older. We can't tell".
Carbon dating is only used for dating specific things for that reason. There are other ways of dating things.
I misread the thumbnail
thought it asked when we became U. S.
thought 'What an easily googlable question SciShow. What's the twist?
When will human become smart enough to never blindly follow a leader that lead them to death and destruction?
From a different perspective....Could not have these "modern human" traits, been latent in the genome for quite some time? Just awaiting opportunity for expression? Could it be that it was population pressures and drivers that created language out of a newly presented need to human kind. Rather than seeing language as an independently driven expression of the genome?
I find the Stoned Ape Hypothesis compelling. The human brain developed at an alarmingly rapid rate, and the logistics and effects of psilocybin could easily explain it.
Even today, our collective nostalgia seems easily explained by a separation from our deeper consciousness - which psilocybin easily reconnects.
I find it compelling as well, but I think the question is more one of "when did our relationship with it start , 35,000yrs ago or 3.5mya, and how much of an influence has it had on our evolution in that time?"
@@Ghost2743 That's a good point. I suppose it'll be difficult to say until we know more about epigenetics. But I would guess that it wouldn't have been very long prior to the first noticeable change in the fossil record.
"when did we become the U.S.?" well as history told me, it had something to do with the declaration of independence
Uh huh, 'Murica!
My country has lost all its balls, we have a government more incompetent and authoritarian than the Brits were to us, but still no revolution.

Who is that cute sapien specimen you showed in the beginning
It seems to me that the Flintstones were behaviorally modern, although I don't know how long ago they lived.
We have arrived to a point where technology dictates our behaviour
Interesting times to be alive
Clothes, weapons and tools have been dictating our behavior since before we were any type of "modern" human. Technology was literally necessary for us to evolve into humans..
(Sorry for bad english, and im just saying my opinion. I like philosophy so i like asking questions about stuff like this.)
+@UCCsucG-6zp7-3XvvmsNKMPQ
Cant you then also say that our behaviour have dictated our use and development of technology instead? And that we have made stuff to work perfectly with our behavior and psychology. Summarized: Our behaviour dictates what we want, therby what we create is shaped acordingly to what we want. What do you think?
That tech dictates our behaviour is also a bit wrong...It predicts and responds on that prediction. Like mapping your characteristics, and then sending ads to you about stuff fitting those characteristics. It does not chose you like bikes or cars, but it predicts you do. If you know all the facts, then manipulation from computers is also mostly impossible, and there are always humans behind that manipulation as well. But i guess it is also a question of free will. Do we have free will to respond to our wishes behaviours and urges? And if yes do we have free will to chose what we wish and urge for? And if yes or no, can tech influence that decision?
I feel like behaviours are the things we do that can observed (externally). For a psychologist these are some of the only things that can be measured. Behaviours are not motivations. Perhaps motivations can be implied by behaviours (why did she get that apple? Because she was hungry) but that leads us to supposition, which often makes bad science (maybe she eats out of boredom or another reason).
To say therefore behaviours cause technologies (paraphrasing: behaviours dictating use or development of technologies) seems to me a statement that misses lots of steps and abstract thought necessary for creating technologies. The root of technology is tekhne from the greek for craft, as in a skillful thing, but the complex thought required for development also requires design, problem solving, intentionality, purpose ect
In short behaviours are the things the we do, not the why. Maybe technologies change what we do, or how we do it, but intent can no more be ascribed to a microwave oven then the act of turning it on.
To say that the advent and persistence of a technology creates or alters behaviours to me seems far less controversial,
and the point that mundane technologies such as clothes have altered our behaviour for a very long time was so in your face obvious to me I'm glad someone else pointed it out
@@cooblin3607 I like your train of thought here. I'd say that its probably a bit of both, we tailored technology to our behaviors and needs all while technology tailored our behaviors in ways we didn't expect in the process of tailoring it to ourselves? In short, technology changes us while we also change technology. Which does more changing to the other is most likely dictated differently in different situations?
Nevermind 10,000 years of religious indoctrination convincing plebes to build monuments of wealth on behalf of a minority of murdering thieves.
We are neotenic apes; many human behaviors are present in many other mammals and especially apes
Basic brain power or more advance smarts? Im seriously questioning the emphasis on brain anatomy being sole cause of human behaviour changing... I dont think humans before "behavioral modernity" had brains uncapable of doing things we started doing later on... obviously there is a connection but its also just the cultural setepping stones that have to be reached in order to advance in the complexxity of our behaviour... place a modern baby in a context before "bhevioral modernity" and he would not, as you say, have an eureka moment and start singing, and painting.. no this baby would adapt to its society in order to survive.. and while he may end up pioneering some sort of behaviour it would be, in the case of pre modern humans too, a lot of chance interactions with the environment that would develop into increasingly complex behaviours. Just like you can teach a chimp things he would never learn in his natural society, also the brains of pre modern humans could in most probability do almost averything we do today, they simply didint because their society hadnt reach that level as a cultural entity which builds up knowledge and compplexity through time and is passed through living thinking individuals, not genes, so there was no one to teach those humans the sorts of complex behaviors we arrogantly believe to be the only ones capable of. All feedback welcome, im I alone in this perspective?
Burials?
Hank: "But what about the most defining characteristics of behavioral modern humans?"
Me: Watching cat videos.
*proceeds to get disappointed*
When did modern behavior evolve? I don't think that has happened yet! I'm still waiting.
Are there any genetic differences between Homo sapiens 300k years ago versus 40k years ago? That is, does our modern behavior come with significant differences in our genetics?
Maybe a bottleneck event or two?
If you want to discuss recent evolutionary history of our specie, there is an ideological minefield in front of you. If you admit:
- there had been any evolutionary pressure on our cognitive capabilities in last 100k years AND
- you don't have a way to make this pressure perfectly uniform
THEN
Then you don't end up with perfectly equal outcomes and you are toying with concepts like "human biodiversity" and "race realism".

Scishow do a show on when science actually contradicts psychology. It has happen a few times now and most recently, especially regarding huge assumptions psychology has made. They claim psychology is a science. So what happens when "science contradicts science"
then go with the science supported by clearer numbers and more measurable results. maybe? or with the numbers of psychology only. F.e. if one of its claim is wrong 60% of cases, it is woodoo and not science.
Weapons making to use against other humans. Yep, that definitely sounds like us.
Yeh, like, totally, totally. Like let's get some coffee. Oh, I know, I know. Isn't it just. Well, it is isn't it. Let's selfy!!!
I always wondering, how science calculate the age of something.... Is there a youtube link to that?
I'll explain for you! Basically, when we dig up stuff like fossils, we know approximately how old it is based on how deep in the ground it is. The rate at which sediment accumulates is the same-ish in certain areas, so we can use that to infer how long ago it was put there. Simple, but at the same time not. Does that make sense?

Psycho Social Creation Not exactly
If you know that a free ebook Thiaoouba Prophecy is a true report, then it becomes clear that humans did not come through the process of evolution, but were "born" out of Ovoastromic Egg essentially as they are.
It might sound crazy for some people, but I know that the book is true out of my own experiences.
As for animals, they do come through the process of evolution.
What parts of modern behaviour are a result of nature and how much nurture though? At what point a person taken from the prehistory to let them grow up in modern times would be the same as us? At what point a today's baby put to grow up in the past would stop being the same as others of the time?
I have been a religious person and now am more spiritual. I absolutely believe there is another plane where life continues to exist. I have done a lot of research about religion, what have people believed and why.
A lot of religions or groups have a creation story explaining how humans, or a specific people of tribe, suddenly appeared on earth. Beliefs range from Adam and Eve to crawling out of the earth or awakening under leaves in a taro garden.
So I have wondered if humans remember back to a time when we transitioned from very primitive to advanced? Indigenous Australians speak of the Dream Time. I wonder too if many humans had to seek sanctuary in caves during the ice age and if during that time, civilization advanced? I wonder if these social advancements during a time of restrictions fed creation stories about crawling out of a hole in the earth? Maybe there was a big event which caused humans to advance rapidly?
In support of this, modern writers working from ancient texts like to claim space aliens taught humanity. I do not agree with the space alien theories but again I wonder if an event caused humans to suddenly advance in ways or learn from others to the extent it appears a superior group brought knowledge?
I suspect that self awareness had a whole lot to do with how our brains developed. I wonder if we had help?

Eh, whether or not abstract geometric art displays less abstract thought than symbolic art representing animals seems like a matter of opinion to me. Personally, I'm inclined to think that abstract geometric art like that depicted in the video requires more abstract thought than a drawing of an animal, because instead of simply trying to copy something you see, you're creating a pattern that's completely new, that you've never seen in the natural world.
In any case, at this point there's plenty of evidence of behavioral modernity in the african middle stone age (long predating the

Our modern behavior cannot be this recent, if it was it would not be uniformly or even totaly spread through all human ethnicities
