00:00

as the science of Life biology is about

00:02

everything that lives grows poops and

00:05

dies if you're breathing right now and I

00:08

sure hope you are that's biology at work

00:10

and it's not just happening inside of

00:13

you but also above you below you and all

00:16

around you basically biology has got you

00:18

surrounded it's in the medicine you take

00:20

when you're sick and the vaccines that

00:22

keep you from severe illness it's in

00:24

your dog selectively bred to be your

00:26

best friend it's in your body's 30

00:28

trillion cells working hard behind the

00:32

scenes as you belt out some Beyonce in

00:34

the shower I can see your bio oh your

00:37

bio and in the 40 trillion microbes

00:42

treating your guts like an apartment

00:43

complex as you digest last night's Pizza

00:46

it's also in last night's Pizza we owe

00:49

the wonders of tomato bread and cheese

00:51

so the power of soil sun and

00:54

photosynthesis biology is behind the

00:57

pineapple as well though I'm not sure

00:59

who's to blame for putting pineapple on

01:01

pizza and I know that this is like a big

01:03

argument these days but my hot take is

01:05

it's all right no shade so really

01:07

biology is about everything alive and

01:11

what makes life worth living now I know

01:14

some of you might be thinking didn't you

01:16

already do a biology series yes we did

01:19

and Hank's goatee won't be back for this

01:22

one but we're using everything that

01:24

we've learned over the past decade of

01:25

Crash Course to make you an even better

01:27

series biology 2.0 if you will

01:32

hi I'm Dr Sammy your friendly

01:35

neighborhood entomologist and I'll be

01:36

your host I'm the endowed professor of

01:38

Entomology at the University of Colorado

01:40

Boulder where I study honeybees and

01:42

teach about symbiosis and science

01:44

communication my work focuses on how

01:46

creatures form super close amazingly

01:49

complex relationships like the ones

01:51

between pollinators and flowers that are

01:53

responsible for much of our food or the

01:55

parasites munching on the bee's liver

01:57

that threatened that intricate balance

01:59

of pollination

02:00

we'll talk about lots of fascinating

02:02

stuff like this and more in this series

02:05

our new crash course biology or head on

02:09

over to crash course in espanol to watch

02:12

Crash Course biology hosted by many

02:14

Contreras over the next 50 episodes wait

02:18

50 we get so we're gonna put

02:23

this fine we got this we got this

02:27

over the next 50 episodes we'll find out

02:30

just how connected life really is we'll

02:33

Zoom between itty bitty cells and vast

02:36

Global Cycles we'll discover how species

02:38

evolve how genes work and what the heck

02:41

happens inside a cell anyway and what

02:44

sends nutrients ricocheting from soil to

02:46

your stomach and back again we'll also

02:48

take a look behind the science through

02:50

the stories of biologists both past and

02:52

present that you might not have heard

02:54

before like how Dr anurag Agarwal found

02:56

out that chewed up radish plants fight

02:58

back against very hungry caterpillars or

03:01

how Dr Jane cook Wright proved that a

03:03

chemotherapy drug still in use today

03:05

could work at a time when chemotherapy

03:08

was thought to Taboo or absurd at the

03:10

same time we'll see how biology can help

03:12

us respond to our Global challenges like

03:15

hunger access to clean water and climate

03:17

change we'll find that it's not so easy

03:19

to pin down exactly what life is but

03:23

that one little word life connects

03:25

living breathing you to every bug bat

03:29

and Barnacle that has ever well lived so

03:32

join me as we explore our place in a big

03:35

diverse family tree about four billion

03:38

years in the making I'm so excited to

03:40
