The relation between hand morphology and quadrupedalism in primates.

Primate hands can be classified into two broad categories on the basis of ray proportions and other features. Ectaxonic hands are characterized by a longer fourth ray and are found in most strepsirhines. Most haplorhines possess mesaxonic hands which…
