The Unbroken Thread
All life is related
And it enables us to construct with confidence
The complex tree that represents the history of life
Our planet,the Earth, is as far as we know
Unique in the universe
It contains life
Here plants and animals proliferate in such numbers
That we still have not even named all the different species
Darwin's great insight revolutionized the way in which we see the world
We now understand why there are so many different species
Every cell is a triumph of natural selection
And we're made of trillions of cells (Within us is a little universe)
Those are some of the things that molecules do
Given four billions years of evolution (We are, each of us, a multitude)
Now how did the molecules of life arise?
[David Attenborough]
It began in the sea
Some three thousand million years ago
Complex chemical molecules began to clump together
These were the "seeds"
From which the tree of life developed
They were able to split replicating themselves
As bacteria do
The secrets of evolution
Are time and death
There's an unbroken thread that stretches
From those first cells to us
The secrets of evolution
Are time and death
There's an unbroken thread that stretches
From those first cells to us
Every cell is a triumph of natural selection
And we're made of trillions of cells (Within us is a little universe)
Those are some of the things that molecules do
Given four billions years of evolution (We are, each of us, a multitude)
There isn't a sharp line dividing humans
From the rest of the animal kingdom
It's a very wuzzie line
It's a very wuzzie line
And it's getting wuzzier
All the time
We find animals doing things that we
In our arrogance
Used to think was "just human"
It's a very wuzzie line
and it's getting wuzzier
All the time
Every cell is a triumph of natural selection
And we're made of trillions of cells (Within us is a little universe)
Those are some of the things that molecules do
Given four billions years of evolution (We are, each of us, a multitude)
Every cell is a triumph of natural selection
And we're made of trillions of cells (Within us is a little universe)
Our planet,the Earth, is as far as we know
Unique in the universe
It contains life
Its continued survival now rests in our hands
