__Punctuated equilibrium__ - contrast with gradualism, which states that evolutionary change happens slowly but surely. Punctuated equilibrium states that organisms stay in stasis (period of no change) for long amounts of time, and then change quickly according to evolutionary mechanisms.

__**Lyrics (sing along :)**__

This is. This is. This is. Punctuated equilibrium. At first you'd think that evolution would go gradually. But the ancient fossil record states the theory oppositely

Rapid change. Yes there's rapid change, change. Without the proof of intermediate stages discovered, Change is, spontaneous

Now take your average kind of bird that's rather rather plain It will remain in one species so that it seems not to change In in time, in a point in time, time Dramatically evolving the new species is born in response to environmental change

__Chorus:__ Geographic isolation, where did the rest of us go there is only one of me here because of...

Punc-tu-ated Equi-li-bri-um Sudden change from environmental factors Punc-tu-ated Equi-li-bri-um New species from sudden evolution Oh Ye-a-ah

Thats right, right Life wont ever stay the same Thats right, right There's nothing we can do about that

Thats one Branch, then Two Branch To the Left, To the left One Trait, a new trait to the right (refer to picture on gradualism group's page)

This form is the best that I ever had I am so well suited to my environment Although I am so different from my parents its quite all right, I will have more children :]

When the old traits are completely wrong My new traits will be so right My brand new generation, yeah, I will be Better, Faster, Stronger (Survive)

My new generation is of the best quality Forget the traits I used to have they aren't so good for me

On and On Yes, we're going on and on

Until the next environmental change my species will remain the same

//Chorus//

Evolution occurs so suddenly One moment a species seems to stay inert For the sake of an unexpected change Species will be much transformed anew

//Chorus//
