No ah long long time ago human being started farming

00:06

and they were like hey this is kind of cool

00:09

now we don't have to eat all these critters around

00:12

us so they gathered their critters and said hey we

00:16

don't have to eat you anymore so you guys should

00:18

just hang out with us You don't even have to

00:21

pay rent and all the animals gave them a dumb

00:24

luck shrugged and kept rolling in their own Cooper that's

00:27

how animals were domesticated right Ok not exactly shmoop version

00:32

well domesticating plants and animals required some serious genetic manipulation

00:36

on the whole process took thousands of years what's funny

00:39

is that our ancestors didn't have a clue that they

00:42

were artificially selecting plants and animals for favourable genes People

00:46

wouldn't know about genes for about well another nine thousand

00:49

or so years early humans were just using common sense

00:53

by choosing to breathe the animals and plants that worked

00:55

best for their needs Well general rule of thumb in

00:58

human history humans always look out for humans first So

01:02

the deeds what We already know that the first animal

01:04

to be domesticated was some kind of dog they helped

01:07

Us out way back in our hunter gatherer days But

01:10

we didn't eat them They're usually the first animals to

01:14

be domesticated for agricultural purposes Were sheep and goats in

01:16

eurasia around ten thousand b c e mail Sheep and

01:20

goats were already pretty friendly Lived in herds and ate

01:23

pretty much well Anything green plus goats could faint which

01:27

always livened up a long day full of goats Yeah

01:31

well after goats we domesticated pigs around nine thousand bc

01:34

They were especially handy because well they're easy to take

01:36

care of clean their room Just let him roam around

01:40

eating literally everything And then a few months we have

01:42

bacon Well after pigs we domesticated cattle in about eight

01:45

thousand bc and horses in about four thousand bc Over

01:49

time each of the species became better and better adapted

01:52

to human direction She got william pigs got fatter and

01:56

nicer and cattle turned into milk's villas and goats Swelling

02:00

goats worked on entertaining us with fainting and having weird

02:03

eyes Throughout the process we were accidentally domesticating food crops

02:08

too The most important ones were probably wheat rice maize

02:11

barley and different kinds of beans Well those were that

02:14

Calorie rich crops that fed the biggest most impressive ancient

02:18

civilizations and their animals Domesticating plants and animals gave us

02:22

more than the many near mutant like breeds of dogs

02:26

We see it dog shows well here are some specific

02:28

things that domestication changed for one it's spreading new diseases

02:35

Yea well humans and animals started living closer together and

02:38

the animals themselves were not naturally selected for their awesome

02:41

immune systems So new diseases started to spring up and

02:45

jump between us Some diseases wiped out animals and others

02:49

attacked humans Can you say black plague Anyone Well plants

02:53

and animals also fundamentally changed Domesticating an animal does more

02:57

than make it friendlier Animals also get a little dumber

03:00

and slower because they no longer need to escape predators

03:03

So next time your dog fails his calculus test Well

03:06

he'll know who to blame Plants lost their defence mechanisms

03:09

as well Thorns and sticky sap went away in some

03:13

species That's right Plants and animals are totally soft now

03:17

on humans also changed That's right animals changed us humans

03:21

adapted to their new sources of food One of the

03:23

most dramatic changes was lack Toast tolerance will paleolithic humans

03:28

Couldn't drink animal milk without getting sick but over several

03:32

generations of living with herd animals and drinking milk anyway

03:36

some humans developed the genetic ability to ingest milk And

03:40

we all have these brave humans to thank for ice

03:42

cream except for the lack tose intolerant who must be

03:45

at least one part cave man or woman Domestication of

03:49

animals also had a big effect on transportation Animals like

03:52

oxen horses and donkeys were super important for hauling our

03:56

stuff around whether they liked it or not And last

03:59

but not least they were an energy source Yeah look 00:04:03.25 --> [endTime] at that little guy Go that terribles
