The phenotype is remarkably variable. Cockatoos, basking sharks, otters and camels display far less variability in their general appearance than we do.
I find the subject fascinating. We have very different appearances, although I have noticed some features that seem to be regional—for instance, I recognize a general “Maryland” appearance in people whose families have been established here for hundreds of years. Our genetics, OTOH, are remarkably non-diverse. Although a species’ fitness is tied to its genetic diversity, we seem to be doing fine.
