Other assymetries exist in nature. Nothing yet shown proves that Coriolis is the driving mechanism in draining water. What drives other assymetries?

How about assymetric life forms? Do abalone shells wrap in oppoiste directions north or south of the equator? You boys in OZ probably have an abalone shell around. Which way does it swirl? My California abalone shell, looking at the pretty inside, swirls outward counter clockwise.

How about the leaves of the begonia plant?

I seriously doubt if molecular assymetry can be attributed to Coriolis effect. D-glucose rules North or South. Perhaps identical global chemical assymetry results from similarly polarized light hitting the entire earth's surface, an identical polarization induced by a yet unknown atmospheric mechanism which.....?

Hmmmm....more coffee needed. Or maybe less. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
