The Cognitive Trade-Off Hypothesis

[Verse 1]
Did you know
That years ago
All we had
Was sticks and stones
To make our food
And build our homes
We collected birds
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
And eatin’ on bugs and little berries

[Chorus]
We climbed down from the trees
And we learned to speak
We lost all of the hair from our bodies

[Verse 2]
Our ancestors were very weak
The other chimps kicked 'em out of the trees
And they were forced to learn how to speak
In exchange for other important things
But 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

[Chorus]
We climbed down from the trees
And we 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?

[Chorus]
We climbed down from the trees
And we 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 down from the trees
And learned to speak
We lost all of our cognitive abilities
We climbed down from the trees
And learned to speak
And we lost all of the hair from our bodies
