Unformatted text preview: Selim 30 November 2007 Extended Male Growth in a Fossil Homimn Species Charles A. Lockwood, Colin 6. Menter, .Ziacopo
Moggi—Cecchi, and Andre W. Keyser “In primates that are highly sutually dimorphic,
males often reach maturity later than females,
and young adult males do not show the size,
morphology, and coloration of mature males. Here
we describe extended male development in a
hominin species, Pomnfhmpus mbusfus. Ranking a
large sample of facial remains on the basis of
dental wear stages reveals a difference in size and
robusticity between young adult and old adult
males. Combined with estimates of sexual
dimorphism, this pattern suggests that male
reproductive strategy focused on monopolizing
groups of females, in a manner similar to that of
silverback gorillas. However, males appear to have
borne a substantial cost in the form of high rates Livesfyle of Homo entry: Tor'r'alba and Ambmna,
