>Thanks, Andrew. I feel more like a chordate now.
I'm glad that you do. These days I don't generally feel as though I
even have a notochord. More like a medusan (jellyfish)... with an
encephalization quotient to match.

Come to think of it, plants... fern fronds are coiled; many plants'
clasping leafbases are arranged in a spiral, as may be flowers on a
spike and scales on araucarian trunks & branches. Brachiopods, some
caddisfly larval tubes (freshwater)...
