Who is the most diverse of them all?

Here is the diversity ranking of Howells' 28 human populations based on 45 cranial measurements. The numbers are the average population standard deviation (for each population over all 45 measurements) as a percentage of the average human standard deviation (for all groups over all 45 measurements). In parentheses, the racial cluster of each population according to my previous analysis.
