That from the dinosaurs the birds in nature have evolved.
Some insects have four wings, while some but one pair sprout,
But birds with only two wings in the clear air fly about.
Yet now from China comes the word, with evidence from yore,
That early birds - and dinosaurs - had not two wings, but four!
While normally from Nature our wisdom we derive,
In this instance from engineers to learn our ways we strive:
Recall the early biplanes – two wings on either side!
Modern technology would not such things abide!
For in nature, as in our lives, the answer is sublime:
What is more efficient will win out every time!...
