On reading a book review entitled “In Darwin’s Footprints”

The new and improved opposable thumb
Can handily (you will pardon the pun) grasp
A tool, a stick, a pen, a glass of ***
(But dareth not to clasp Cleopatra’s asp)

If we are descended from sophomores
Then why are there still sophomores in the wild
Or random selection from random spores
Mutating from flower to flower child

I don’t know

But it’s a useful thing, my dear old chum
This new and improved opposable thumb
