Khan helped me pass chemistry in high school and here I am 10 years later learning out of pure curiosity lol
What's even more amazing is that for those who didn't know: hunting-gathering has actually been going on for nearly 2,000,000 years! All of our early relatives were also hunter-gatherers beginning with homo erectus nearly 2 million years ago.
Now try comparing 10,000 years with 2 million years.
They were scavengers and herbivores, not hunter-gatherers

Kahn Academy is simply amazing. Informative, clear, concise, and interesting. Thank you.
kewl
you could have talked about theories how and why agriculture emerged. there were findings of early forms from 20k years ago and theories about the use for alcohol.
this is the most informative and concise video I found! Some of them went very very deep and kind of missed what I needed.
As an educator I want to know, what program or device is Khan Academy using to present these videos? Can anyone answer this?
software called virtual blackboard is a possibility
There are some studies estimating the first sporadic domestication of plants at least 23,000 years ago. I guess since the Ice Age was subsiding gradually, starting in different places, the same theories still applies. Some areas with micro-climates must have become favorable before the 15,000 years mark for the end of that glaciation.
Khan Academy is very informative, precise, and the videos are very informative for the students as well as for the teachers to use it as reference..
Love your explanations, sal! Makes everything interesting ...
Agriculture didn't lead to warriors. They already existed. Nomadic hunter-gatherers were warriors. Look to the historian and author David Frye.
You've made an error, I think, regarding agriculture.
You are likely correct about when people developed agriculture, but not correct about the transition from hunter gatherers.
Long before humans started cultivating plants they were harvesting wild plants. Archeologists have found clear evidence of pulses and grains being ground for food tens of thousands of years earlier. We don't yet know how this transpired, but it seems reasonable that pre-agriculture gatherers would settle seasonally to harvest regular wild crops.
Once humans discovered sizable wild crops could be converted to food, it would dramatically change their approach to where they lived. This need not have waited until we learned to cultivate those plants. In fact, who knows how long it might have taken for humans to realize they could or should cultivate crops?
It seems most likely to me that cultivation began after tens of thousands of years of making settlements near those naturally occurring crops, before demand caused them to plant those crops themselves. If that wild food stopped growing, or didn't produce enough, they would migrate to new areas.
Hunter-gatherers became hunter-harvesters, and much later hunter-cultivators.
The birth of agriculture followed tens of thousands of years of collecting wild crops. This allowed settlements prior to humans actually cultivating crops. Sites in Turkey like Gobekli Tepe are showing people in large settlements much earlier than we thought. I suspect we will find earlier ones still.
And when it comes to hunter-gatherers, it probably should be changed to gatherer-hunters, if defined by caloric quantity. Wild meat is an unreliable food source. It runs away and fights back. It is hunted, but not as a main food source, save some particular isolated groups. Populations thrived and grew where food was abundant, even before they started planting it.
I mean this series is much better than the crash course one!! Why do people tend towards that!!
Udai Gill Crash Course is for less intelligent or maybe younger audiences
Yeah those want to be impressed by the host's style rather than learn the topic in depth!
1:00 wow the first stone really doesn't look any different from the other stones when you think about the time difference between them
Helps Alot!
Thank you!! I love all your videos :)))
the biggest population boom was caused by a specific type of agriculture called Terraforming. Its all thanks to the domestication of the cow and her 4 stomach she can eat almost anything even grass and moss or evergreen tree spikes. And after digestions 63% of the energy of the plants the cow ate end ups in this fertile dirt that she produces. (i say dirt because youtube considers the real word as taboo) Most of the dirt in farms today is actual cow made dirt. Without it, the yields of all farms drop by between 80% to a hundred depending on what kind of soil you are on.
The video is talking about timeline and importance of agriculture. Only very less content about origin and spread.
The person who talk is Salamn Khan but is it he who prepare all informations or others persons ? If is it other persons, could I have the names of these persons please ? It's for my dissertation.

How Artistic! 👌 👌 👌
Excellent video, thank you.
this helps me out
How do we know that before the 2nd ice age, there was no agriculture? I mean it was probably inevitable that in a population of 10ml, over dozens of thousands of years, somebody came up with that idea
I don't think they've found evidence to support that
Hard to believe that you could do that without the use of language (around 50k yrs ago)
For 180k years nobody figured out how to plant a seed
Well they used to say 150.000 to 200.000 but I believe they have pushed that up. In my opinion it's more like 350.000 if not more you got to think we change that when we find more fossils and we know there more. We found alot tho.

What about that hammer they found in that stone or whatever that was like 2 million years old?
And that spark plug thingy that's just as old? I Need ANSWERS!

Agriculture began in Nanchoc, Peru.
woah coolio
yeah
live ur vids thank u so much
So glad we live in a time and place where we don't have to mass kill anyone just to eat. We don't even have the resources to sustain our species growing population on a diet based around meat, dairy, and eggs.
Thankfully we have no nutritional or biological requirement to consume animals or their byproducts.
Our plant agricultural techniques are becoming more efficient while demanding less resources which is cool and by feeding grain directly to humans and skipping out on feeding it to all the livestock we keep breeding then we could really begin to eradicate starvation.
This could in turn cause a spike in human population which may not be so nice lol so plan parenthood should definitely be funded. That's a whole different ball game...
Glow you THINK meat is essential to humans. Why?
Our ability to sustainably develop and scale plant agriculture is actually pretty awesome. We are technologically advanced enough to thrive on this planet but the issue seems to be corporate and political profit rather than the well-being of our species as a whole.
Plan parenthood plays a huge part in the health and wellbeing of women especially. Being able to have access to birth control should be a priority considering our systems current inability to sustain our population.
Plenty of kids need fostering and adoption anyway. Plenty of kids go hungry everyday while we fatten up cows and pigs and chickens and over fish our oceans.
It's illogical and unethical. No hate ❤✌
Neoteric Phoenix the vegan in me agrees. Not so sure abt the abortion bit, but it's a valid opinion.
@@neotericphoenix5811 meat is essential to homo sapiens as we have evolved to consume it. That's why in vegan diets there must be placeholders for meat.
Theres much evidence to suggest that not many in the paleolithic starved and if they did it would have usually been the result of an external disaster or event. The variety in paleolithic humans diet alongside their expert knowledge on hunting and gathering meant a band of hunter gatherers often wouldn't have gone hungry. Famine is the hallmark of agricultural societies.
@@neotericphoenix5811 I wonder why our current system struggles or sustain us. Could it be linked to the fact that humans evolved to live in small communities of 150 and not cities of 500,000
Not very simplistic thinking. Definitely not enough. It is just speculation far from truth.

Orgins. Oh wait, you meant to say "origins". You probably should change the title.
knight wing the title clearly says "origins of agriculture"
Blown Away Look at the first word.
knight wing yes, it is spelled "ORIGINS"
Blown Away No, they mispelled it. Look closely.
knight wing how did they misspell it? It is spelled O-R-I-G-I-N-S, at least that's what my eyes see and my brain confirms it to be true. Or we both are seeing two different things?
You may also include accidental agriculture through humans collecting the most nutritious specimen of plant food and excrete or discard seeds near their camp sites where these seeds would have a sunlight and soil fertility advantage from such compost and if they germinated and grew they would have genetic advantages of being in the vicinity of other preselected specimen. Such accidental planting sites may then attract other roving hunter gatherers who would compound this effect.
Yes, this is glaringly missing. Humans didn't just decide to try cultivation. It was a natural outgrowth of gathering, which produced refuse and indigestible waste.
It's not impossible either that some random ancient person just observed nature for a long time and thought, "Ok things grow... how is that possible and can we do it ourselves on purpose?" ancient humans weren't dumb, especially not in collectives.

SAL KHAN,
ACTUALLY, RICE EMERGED FROM KORAPUT, ODISHA, INDIA; & NOT FROM CHINA!!! IN FACT, INDIA HAS GIVEN RICE 🍚 AS A STAPLE FOOD 🍲 TO ALL OF THE EAST & SOUTH EAST ASIA, & MAYBE EVEN WEST ASIA, OR EVEN FURTHER TO EUROPE THROUGH ARABS ONLY!
Good point
pov ur history teacher made u watch this
Agriculture is mentioned immediately after being thrown out of the Garden of Eden.
profe porque me hace esto ;-;
JAJA, te comprendo amiga :'/.
@@dctorss suerte , la mandé ayer mi tarea :'v
@@celeste9173 Gracias :,)
My theory as to why humans didn't develop agriculture within the space of over 150k years is simply because our species is far younger than 200k years old. There is no way a species would take that long to develop a better or alternative way of life, especially not humans.
I think we were lucky enough to discover agriculture.....that changed everything
Dude theres still tribes that have not discovered agriculture.
@@noirchu5844 WHO? WHERE?
Are you drunk?
i dont understand that why humans took 150000years to start agriculture, untill then they were different poeple ?
