At the risk of starting a whole new level of jokes, another organ which varies a lot in size (especially if we consider volume instead of just length) is the penis.

Which suggests to me the hypothesis that features that may have been subject to sexual selection in humans have gone through a lot of change in a relatively short time and therefore show a large distribution.

Then again, there are other, non-sexual organs showing a large distribution as others have pointed out (e.g. noses), so maybe there really is no anomaly to solve here?
