 * Trying to think of a counter example, handedness? That's fairly bimodal, not immediately obvios tha it's cannalized.  Most f the bimodal examples I can think of Does this example (borrowed from Ridley's Nature via Nurture I think) relate?  There are some mutations producing non-5 digit numbers in humans, but the overwhelming number of humans get 5.  Extreme environmental influences, chemicals inducing birth defects, or bandsaws, contribute most of the variation.  Example shows that low heritability  does not mean that genetics does not have a strong effect.  Anyway, a concrete example of cannalization would be super valuable here.
