People thought all animals
Arrived here unrelated
The world began, and then came man
All perfectly created
But then someone looked up a tree.
And said "That monkey looks just like me!"
So it really was a mystery
What I'd learned in natural history!
So I joined HMS Beagle
Watched the eagle and the seagull
We studied rock and plants
Flowers, trees and bees and ants
Slept on hammocks without pillows
Eating rats and armadillos
Till I realised on reflec-tion
It's natural selection! Yeah!
Natural selection means
Each animal evolved
To blend with its surroundings
Ch-ch-changes were involved
So birds with different, foods to seek.
Seem to have developed, different beaks.
And over time they'd,
Modified
So just the fittest
Of them all survived!
On the Isles of Galapagos
I noted the giant tortoise
Had interesting shells
And I rode on them as well
Iguanas land and swimming
Meant my new theory was winning
It all led in the direction
Of natural selection.
My findings went with outrage
From the ch-ch-ch-ch-church of England
And from me.
The idea that we came from ch-ch-chimps
Questioned my own Christianity
But it was hard to disagree!
Every species new mutation
Had a perfect explanation
It seems the worlds inception
Must predate common perception
And if lack of adaptation
Means a fatal limitation
So each creature's imperfection
Over time gets a correction
Meaning animal collections
Grow unique means of protection
And to fail nature's inspection
Means immediate rejection
Which all leads to the detec-tion
Of natural selection!
Natural selection!
