PIP: The relationship between anthropometrics and 3 measures of Darwinian fitness--number of surviving children, number of living siblings, and marital status--was sought in a population practicing no contraception.

The dimensions studied were those least intercorrelated one with another. Stabilizing selection for human physical characteristics may not be a universal phenomenon.
