Reference: Hallam, Anthony, An Outline of Phanerozoic Biogeography,
Oxford, 1994, 191.

In Hallam (1994), the author states: "The tendency of small herbivorous
mammals, such as rodents, to enlarge, and carnivores and ungulates to
dwarf on islands seems to have fewer exceptions than any other ecotypic
rule in animals (Roth 1992). 250 gram (the weight of a small rabbit) is
the fulcrum, . . ."

If Alex Duncan is correct, we should see a secular increase in hominid
size during the evolution of bipedality, but if Elaine Morgan is correct,
we should see dwarfing during the same period.
