Hello,
Did you know that Homo sapiens can also be 'sinistral'? I met a lady one day whose organs are the other way round. She wore a bracelet to indicate her condition, so that if she goes to an emergency service with a severe pain on the right hand side for example, it will definitely not be her appendix!

I'm looking at shells from an evolutionary standpoint. There are so many
right handed shells and so very very few left handed shells - worldwide
(which rules out Coreolis effect as a cause). The most common example of a
"lefty" here in Florida is Busycon contrarium (sinistrum). Any thoughts on
why this should be so would be welcome to me and maybe to the list.
