D#  E

F  E
Mm yeah
F  E
Mm yeah

[Verse 1]

C
People thought all animals
Am
Arrived here unrelated
    Em              D#m
The world began, and then came man
    Dm        F
All perfectly created

[Pre-Chorus]

    F
But then someone looked up a tree.
               E
And said "That monkey looks just like me!"
      F
So it really was a mystery
         G
What I'd learned in natural history!

[Chorus]

     C          E
So I joined HMS Beagle
            Am             C
Watched the eagle and the seagull
   F
We studied rock and plants

Flowers, trees and bees and ants
         C                E
Slept on hammocks without pillows
       Am       C
Eating rats and armadillos
       F
Till I realised on reflection
     A#      C
It's natural selection!


    F        E
             Yeah!

[Verse 2]

C
Natural selection means
     Am
Each animal evolved
   Em             D#m
To blend with its surroundings
      Dm           G
Ch-ch-changes were involved

[Pre-Chorus]

   F
So birds with different foods to seek
              E
Seem to have developed different beaks
         F
And over time they'd modified
            G
So just the fittest of them all survived!

[Chorus]

       C        E
On the Isles of Galapagos
  Am            C
I noted the giant tortoise
    F
Had interesting shells

And I rode on them as well
C                E
Iguanas land and swimming
         Am             C
Meant my new theory was winning
       F
It all led in the direction
   A#           C
Of natural selection

[Bridge]

    F
My findings met with outrage
         A#
From the ch-ch-ch-ch-Church of England
C           F  C
And from me.
    F                            A#
The idea that we came from ch-ch-chimps
                         G
Questioned my own Christianity

But it was hard to disagree!

[Chorus]

      C           E
Every species new mutation
      Am             C
Had a perfect explanation
   F
It seems the world's inception

Must predate common perception
       C            E
And if lack of adaptation
        Am         C
Means a fatal limitation
        F
So each creature's imperfection

Over time gets a correction

        C      E
Meaning animal collections
        Am              C
Grow unique means of protection
       F
And to fail nature's inspection
      F
Means immediate rejection

Which all leads to the detection
   A#      G# A#   C
Of natural selection!
A#           C
Natural selection!
