Where It Could Go With An Evolving Flow!

So the cat will tangle with old Darwin today. What else do I have to do at my bay? I could eat a little hay. But that might cause my digestion dismay. Maybe a past version of the cat needed the hay for this and that.

Humans were small,
Humans were wimpy.
Not even the size of a ball,
They were really shrimpy.

Then along comes this,
Along comes that.
Science is bliss,
Not to the cat.

They grow into an ape,
They even have a tail.
With a brain like a grape,
Could be an epic fail.

Isn't a fail a fail?
Epic is a strong word.
What is that you wail?
Okay, on with it, you turd.

They get a club,
They get some meat.
What's up bub,
They do the caveman beat.

Then they wear clothes,
Thankful for that.
Could cause eyes woes,
To this poor cat.

Now here we are,
Fighting from afar.
Which is still on par,
With every past sand bar.

Maybe backwards it will be,
Humans turn to paste.
Shrimpy from sea to sea,
What a waste.

At least the cockroaches will be happy,
They will dance a jig.
Maybe they'll eat Flappy,
Then they'd grow awful big.

Or maybe they won't terminate,
Instead add mechanical parts.
That would be an interesting fate,
A machine with a heart.

That is where the cat's thoughts roamed today. Well actually months ago at my bay. But what they heck, good to have another on deck. Now I will evolve my sass, right, not likely from my little rhyming ass.

Fill your rummer, get drunk all summer.
