Lobsters of the Land
Life arose from the sea, so they say,
And Earth’s family tree is still branching today.
Our view of the old structure way down below:
Mysterious, shrouded, a faded tableau.
A mandible here, a common gene there,
From shards of the past, a crusty forebear!
Butterflies, beetles, scorpions, fleas
Have much more in common with life in the seas
Than with other critters that you might expect,
Like spiders and millipedes, things kids collect.
The closer we look, the weirder it gets,
But it also makes sense – the twin silhouettes,
Those strange compound eyes, a similar brain …
Meet Pancrustacea, the base of the chain!
Crustaceans and insects, shrimp and lacewing,
Peas in a pod that sometimes will sting.
Cockroaches, grasshoppers, flies all a-flutter,
Think on them as you eat lobster with butter!
