It took some heavy digging and a lot of clever research.
But scientists have now explained in full detail how evolution works.
Finally it all comes together after much debate and so much time.
(To appeal to the little 'uns they even told it in rhyme).
"And from the mud-baths of primordial soup we came to be.
Rising from the currents of a ginormous boiling sea.
Once things cooled down a bit, leaving cells with room to breath,
things developed quite gradually,
as each individual body part became part of the team."
The Mouth said to the Ear:
You there! Get your Butt over here!
What the Mouth didn't yet know, however,
was that that the Butt was still processing
in some foul smelling black ether.
(Just ask Nose and he'll tell you clear as day,
that smell was nothing short of risque.)
Mouth's voice was very muffled you see,
lacking the Ear's wondrous ability
to take in sound.
You could see it for yourself if you wanted too
(still Eyeball was no where to be found).
Somewhere along the road the Head came rolling down.
He had great determination in his jaunt,
though those big gaping eye-holes were sure to haunt.
And after a two million year nap,
at long last, the Elbow and Knee Cap
came oozing their way from the horrid soup.
Once attached to Mouth and Vocal Chord, they beamed,
"Pee-YOU that reeks, if Stomach were here I'd surely turn green.
One sure develops an appetite after a billion year fast.
If someone doesn't throw me some grub I don't think I'll last!"
After such great struggle there was still so much to be done
Feet and Legs were still in a hot sweaty run
trying for a thousand years at least to find Crotch and Torso
(To make matters worse they needed Esophagus to get re-hydrated also!).
But after all that I think you will find the struggle worth it.
What great things can happen when we're all so close knit.
We're not perfect yet, as you can see, evolution is a work in progress.
Things could always improve, it just takes time to process.
One fellow man of science inquired a rough estimation
of just how long it would take to grow wings
(some bickering was involved, due to his ridiculous proposition).
The real concern is however being totally ignored,
of which I think you will be completely appalled.
It will probably take another 17 billion years,
at least, to get the Brain installed.
