Sexual Dimorphism in Middle Pleistocene Humans - Ipiña - 2001

Sexual dimorphism in a Middle Pleistocene human population (Atapuerca, Sima de los Huesos, Spain) as well as in a modern human population (Coimbra, Portugal) are analyzed and compared through a measure proposed elsewhere (see Ipiña, Durand 2000) by the authors of this work. The point estimate for the sexual dimorphism in the Atapuerca population has turned out to be twice as large as the one corresponding to the modern human population here analyzed. Although such results should be considered cautiously, given that the sample size of the Atapuerca remains is small, they show disagreement with the hypothesis according to which sexual dimorphism is comparable in the above mentioned populations (see Arsuaga et al. 1997).
