  1. Comment on gaulin and schlegel (1980)Wolfe, Linda D. - Ethology and Sociobiology, 1981 - 1 Hypotheses

    This comment suggests methodological flaws in Gaulin and Schlegel’s (1980) article on male parental certainty and investment practices. The authors take issue with multiple coding decisions and suggest that the findings from the 1980 study ought to be rejected; data does not support a positive association between male parental certainty and investment practices.

  6. Latitude and intersocietal variation of human sexual dimorphism of statureWolfe, Linda D. - Human Ecology, 1982 - 2 Hypotheses

    This article examines the relationship between sexual dimorphism of stature and latitude; data support the association. The authors also find support for an association between latitude and human marriage systems, a variable proposed by Alexander (1979) to explain variation in sexual dimorphism of stature. When societies are categorized by latitude, the relationships between marriage systems and sexual dimorphism do not reach significance. Overall the authors emphasize the influence of environmental adaptation on sexual dimorphism rather than an explanation solely focused on male-male competition.

  10. Sexual selection under parental choice: the role of parents in the evolution of human matingApostolou, Menelaos - Evolution and Human Behavior, 2007 - 7 Hypotheses

    This study reveals that in hunting and gathering societies thought to be akin to those of our ancestors, female choice is constained by the control that parents exercise over their daughters. Since parental control is the typical pattern of mate choice among extant foragers, it is likely that this pattern was also prevalent throughout human evolution.
