Apparently, this can be caused for no reason, or as part of a genetic disorder, or as part of an inocuous dominant gene. The extra digits are either useless or not. It is considered one of the more common birth defects.

Interesting.

What can I say, I hate being wrong. And the easiest way to avoid that is to do the work and make sure you're right.
