[David Attenborough] |
|
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 |
|
[Carl Sagan] |
|
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? |
|
[Attenborough] |
|
It began in the sea |
|
Some 3 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 |
|
[Sagan] |
|
The secrets of evolution |
|
Are time and death |
|
There's an unbroken thread that stretches |
|
From those first cells to us |
|
(refrain) |
|
[Jane Goodall] |
|
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" |
|
(refrain) |
|
[Attenborough] |
|
Its continued survival now rests in our hands |
