A new scientific study suggests there was a parting of ways quite long ago dividing dinosaurs that were able to change quickly from those that were set in their ways.
The difference is this – the prehistoric behemoths who started shrinking rapidly eventually morphed into birds.
When a meteor struck Earth and changed the climate, the “bigs” were thrown off balance and began starving while those creatures who were smaller and lighter had a better chance at survival. Those that didn’t adapt or did so too slowly, were fated to perish.
I’ve struggled to imagine the dinosaurs-to-birds transition. In my mind’s eye I can put feathers on T. Rex, but I can’t picture him being chased away from the feeder by a squirrel.
So I asked Trail Baboon Poet Laureate Schuyler Tyler Wyler to pen a few lines to put this research in context. He deflected the compliment (as usual) and said the very gradual process of natural word selection that would lead to developing original verse on such a scientific topic could take years to complete.
But he could do it in ten minutes if he was allowed to steal a poem from someone else.
That wasn’t what I had in mind, but since the topic here is speedy adaptation to rapidly changing circumstances and time is short, I relented.
Forgive us, Edgar Allen Poe.
Back in the Cretaceous era, dinosaurs still roamed the Terra,
Many of them kept on doing what they’d always done before.
On they plodded, often napping. On occasion they heard flapping.
Lightly feathered flutters slapping, clapping many times and more.
Sounding nothing like the locomotion of a dinosaur.
They knew not what was in store.
One contingent started shrinking naturally and without thinking;
All the rest kept eating, eating, eating, eating, eating more;
Gorging on the food abundant, massive creatures turned redundant.
Every day another plate awash with calories galore.
Plumping up at every pore.
When the skies began to darken, many of the beasts did harken
Seeing that their kind was doomed some moped about, à la Eeyore.
Others, bent to problem solving, rather late, began evolving.
Well behind the group already changing – changing at their core.
Sprouting wings and hollow bones is rather an exhausting chore.
Transformation made them sore.
Dinosaurs becoming birds left some observers lost for words.
While others questioned feathers as an element of what they wore.
Why, they asked, would scaly creatures not retain their scaly features?
Turning into fish that swim instead of avians that soar?
Quoth the Raven: Albacore!
What was your most dramatic transition?
