Recently a study of Cornish traits revealed that a large proportion of people of Cornish descent had second toes that are longer than their big toes. We all took our shoes off at the Cornish Association meeting I was attending and sure enough - most of us had Cornish toes. This trait also occurs when the transverse arch is flat (Morton's syndrome) but many of us had normal arches.
As an interesting side note - the statue of Apollo in Bendigo, where Cornish miners made up 80% of the miners there in the mid 19th Century, has very Cornish toes.

How many Mudcatters have Cornish toes? Just wondering.
