The Forgotten Chimpanzee .... ?!

[Sahara]

I haven't heard Jane in quite a while, so I put it in the CD player and this line just jumped out at me...

"Children of the world
The forgotten chimpanzee
In the eyes of the world
You have done so much for me..."

I rewound several times to make sure I heard it right, and yes, the word really was "chimpanzee"...

Not a word I ever expected to hear in a Stevie Nicks song, if I'm being honest... so what on earth is that line about?!
