Seashells, like people, exhibit right and left symmetries. (In people this is obvious as right and left handedness).
Before the great Permian extinction 90% of Nautalis fossils were "left handed". Now 90% of seashells exhibit a "right handed" symmetry, certain shells with a left based symmetry are highly prized by collectors. Why did this change? And what survival value, if any, does this provide?

Being something of a closeted artist myself I thought I'd share some of my sources of inspiration. No Raphael, Van Goghs or Picasso's here, rather the kind of Ordinary art we all can afford. 3 Links today - in no particular order: http://www.thriftstoreart.com/, http://www.museumofbadart.org/ and finally this: The Throne of the Third Heaven of the Nations' Millennium General Assembly. Of course there's lots more, but this is only the "link of the day" and I don't want to spoil you.

Not to spoil the surprise, but having perused the preview of the book, treat yourself to the reviews, (Over 100 at last count!) or maybe even write one yourself. More collaborative genius here than can be found in any government. . . Link: www.amazon.com
