Able To Adapt Poem by Ima Ryma

In the day of the dinosaur,
The penguins were able to fly,
But then decided they liked more
To be in water than in sky.
It took penguins a while to solve
How to be more fish and less bird,
But slowly did reverse evolve
From wing to flipper, in a word.
Bigger muscle and denser bone
To make a body torpedo.
Light/dark feathers - camouflaged tone.
In time, transition was a go.

The penguins left air - who knows why!
Water was where they picked to fly.
