"The Cognitive Trade-Off Hypothesis" lyrics

Did you know that years ago
All we had was sticks and stones
To make our food and build our homes
We collected berries and we lived in holes
And most of us lived in the trees
We counted things at incredible speeds
We lived a life of simplicity
Eatin' on bugs and little berries

We climbed out from the trees and learned to speak
We lost all of the hair from our bodies

Our ancestors were very weak
The other chimps kicked 'em out of the trees
And they were forced to learn how to speak
And exchange for other important things
Once on the ground, we were exposed
To lions and tigers and predators
So we learned to speak, to share our strategies
On how to survive as naked monkeys

We climbed out from the trees and learned to speak
We lost our detailed short term memories
But what's all of this got to do with me?
Is there some sort of connection to my ADD?

We climbed out from the trees and learned to speak
We lost our detailed short term memories
But what's all of this got to do with me?
Is there some sort of connection to my ADD?

We climbed out from the trees and learned to speak
We lost all of our cognitive ability
We climbed out from the trees and learned to speak
We lost all of the hair from our bodies
