When trying to decipher the etymology of a term, it helps
to know what language the roots come from.    (01)

I was reading an article about "urbilateral" worms from about
600 million years ago.   I wondered why they were called
"city-sided", obviously from Latin 'urbs' for 'city' and
'lateralis' for 'side'.    (03)

Fortunately, another article provided a clue:  the author
hyphenated the word 'ur-bilateral' for the most primitive
worm with two-sided symmetry.    (04)
