[Intro by Dr. Bill Durham from Stanford University]

VERSE 1

So there's this little theory. Some people fear it

But if you wanna know the history of life you gotta hear it

And if you’re feeling leery, then stop and hear me

And what better place to start then with Charles Darwin?

DAAAANG

That's the fattest book I’ve ever seen

The Origin of Species got me feeling like I’m fiending for some

Reading on descent with modification

So many barnacles so much variation!

He got inspired by some finches

Not to mention Thomas Malthus and the struggle for existence

Think about it. If there were hella elephants

Growing exponentially with none remaining’ celibate

We’d all be swimming in elephantal juices!

So what decides who survives and reproduces?

Diverse competitors, environment conditions!

Plus remember what C.D. learned from fidgeting with pigeons

By selecting their fates, and matin 'em

He could shape some pretty wild traits as if creatin' em

And if man could do it. Then why not natural forces?

Diversity + heredity + struggle for resources

Combined together. Weeding out the mockingbirds -

Whose lack of fitness leads to lack of offspring

The successful lineage is free to grow

It's evolution, and is started 3.5 billion years ago

CHORUS

This is how life builds from 3. 5 ‘til…

This is how life builds from 3. 5 ‘til… (X4)

VERSE 2

Yeah, the theory’s making sense

But this is science, so where's your evidence?

Life makes colossal moves

That’s what fossils prove

And archaeopteryx should really jostle you

Plus - take a look at deoxyribonucleic acid

In every cell that I know

The basic building blocks of life – in me

In your mama, in a llama, and in boooobies

Plus in newts, fleas, and protists

And comparing embryos in vertebrates should help you notice

You know this, so let’s hit Galapagos

Where we dropping flows while lava gulls stop and pose

Galapagos – it’s evolution in the flesh

A few millimeters might mean life or death

Speciation got me feeling psychotic

Got 20 finch RIMs and they all prezygotic

A gular pouch! The fire of criers females desire

A sexually selected trait that males acquire

An extraordinary adaptation

A frigate prerequisite for copulation

Amazing! The way that life keep’s living

But the truth is with humans that’s not always a given

So best to show some respect for life lest ya

Forget we all share a common ancestor
