If you learn one thing from this video about the development of agriculture, let it be this: you can always distract the Grim Reaper with an ear of corn.

Shmoop around 10,000 years ago the transition to agriculture was well on
- 00:07
its way it officially started in different places at slightly different [a cave man and woman digging]
- 00:10
times China West Africa South America and the
- 00:13
Fertile Crescent in Mesopotamia now that last one is not to be confused with the
- 00:17
Fertile Crescent role which is an entirely different thing

agriculture probably got the earliest strongest start in the Fertile crescent [an empty desert land]
- 00:25
which is some lovely farmland in modern-day Iraq archaeologists have
- 00:29
found evidence that there were fully domesticated animals and plants in that
- 00:32
area around 9,000 years ago we wonder if they were as obsessed with their [a man taking a selfie with a cow]
- 00:37
domesticated animals as we are with ours well they also started grinding and
- 00:41
storing grain living in settled villages irrigating their fields and making bread [someone squishing a ball of dough]
- 00:46
what about bread bowls well we sure hope so how else would they have enjoyed
- 00:50
their clam chowder but most of those changes were the result of new ideas and
- 00:54
strategies but they came with some important new tools like hose. Hose
- 00:59
were tools used to move dirt around there just sticks with some flat stone [a hose stuck in some dry land]
- 01:03
pieces at one end but don't underestimate them they can be used for
- 01:07
weeding killing digging and zombie killing in a pinch then there were
- 01:12
[a man swinging an aardvark] simple plows called ards yeah they were basically pointed sticks that were
- 01:16
dragged over the ground and named by pirates plowing the ground helped turn
- 01:21
over weeds aerate the soil and create cute little furrows for seeds sickles
- 01:25
also were also a big deal these look like clone boomerang with one sharp edge they [a furrow flying through a crop field]
- 01:31
were used by early farmers to harvest green crops by slicing the cops off the
- 01:35
stalks and by the Grim Reaper to harvest soul and corn then the Reaper loves corn [grim reaper holding corn]
- 01:41
so agriculture developed slowly and took a lot of work but why do we care
- 01:46
well farming was the basis for most of human civilization and it changed
- 01:50
everything from human health to political organization to our
- 01:53
relationship with nature so you know nothing to write home about as usual [a hand writing a letter to mom]
- 01:58
some changes were bad and some were good one positive thing was the creation of
- 02:02
food surpluses when we farmed we were making a big investment in time and
- 02:07
labor and hoping we'd come out with a whole bunch of food at the end of the [grim reaper stood in a field with two kids]
- 02:11
season if our bets paid off we ended up with a
- 02:13
nice surplus of food at the end of the day and our community would be able to [a huge field of crops]
- 02:17
survive droughts or hurricanes or marauding bands of hungry baboon those
- 02:22
guys have no manners all these food surplus is also created larger settled
- 02:27
population more people that hang out together in farm the more food they have [farmhouses and huts on a farm land]
- 02:31
while hunter-gatherers could only hunt and gather so much before their supplies
- 02:36
ran out so their populations a stayed on the low side with agriculture we
- 02:40
suddenly had towns and cities while agriculture also allowed humans to make [a boy holding a sign in a hallway]
- 02:44
a lot of cool stuff they could use certain plant fibers to make cloth like
- 02:49
cotton and silk and the hair and hides of their critters to make clothes and
- 02:53
leather goods so yep that about covers the good stuff what about the bad [children eating plants in a field]
- 02:57
well weirdly agriculture didn't make humans healthier than they'd been before
- 03:01
the agricultural diet didn't have much meat in it and sometimes people ate so
- 03:06
much of the same crops they missed out on important minerals and vitamins and [raining vegetables on a girl]
- 03:10
there were no GNC's back then hunter-gatherers had a more diverse diet
- 03:14
even if they were probably eating fewer calories per person yeah the world was
- 03:19
their GNC basically what we lost a ton of leisure time back in the [father and son hunting in a field]
- 03:23
hunter-gatherer days too - turns out farming is hard yeah we know shocker
- 03:28
it takes more hours of labour to grow our own food than the shades of sand
- 03:31
which meant that the average person's leisure time basically disappeared many [a man driving a tractor through a field]
- 03:36
scholars Imperius also think that agriculture increased the importance of
- 03:39
hierarchy in communities since farming produced surpluses of food it was
- 03:44
possible for some people to eat without contributing to the work and thus the [a giant stand with assorted fruits]
- 03:48
fat cats were born well some people even think that large agricultural systems
- 03:53
encourage things like slave labour again farming was a lot of work and for some
- 03:58
it seemed much more pleasant to force others to do that work than them Oh
- 04:02
humanity what are we going to do with us an agriculture and hunter-gatherers both [a map of a large land]
- 04:06
depleted the world's resources but the mobility and low population of
- 04:10
hunter-gatherers kept the effects of their grabby little hands to a minimum
- 04:15
agriculture on the other hand supported larger populations of people and led to
- 04:19
[lots of smoke bellowing through a town] some serious environmental damage this was especially true for soil quality if
- 04:24
we hang out and grow the same crops in the same field for
- 04:26
a decade or so we're going to have a dusty problem on our hands we might even [a persons dusty hand in an empty field]
- 04:31
have a dust bowl like America had during the Great Depression if only it had been
- 04:35
a bread bowl everyone would have been much less depressed heck if it had been
- 04:38
a fertile crescent roll folks would have been ecstatic [girl throwing a crescent roll into a crowd of people]
