A simple statistical examination by de Sousa Campos et. al. (2002) is available for free online. www.bio.ilstu.edu/sakaluk/bsc%203....man%20behav.pdf To make it easier to discuss and to avoid muddling the "featured themes" I thought it would be better to move this part of the discussion to its own thread. |

The link above didn't work for me. The one belows seems to be OK. What are we to conclude from this unrepresentative sample from a predominantely "macho" society? Please contrast this society with that of the Wodaabe, in Niger (already mentioned). |

Sorry about the link, I thought that I had copied it true. Thanks for fixing that.
On the Wodaabe, I don't see how that is different in effect at all. They are is competition amongst the males for the favor of females.

Another paper which is decently written that addresses some of the methodological criticisms of previous research. Luckily also free online. This paper discusses sex differences in jealousy. www.epjournal.net/wp-content/uploads/ep04462470.pdf From an evolutionary approach, because of the biological investment differences between the sexes, it makes sense that males would be more jealous about sexual infidelity and females more concerned with possibly losing the resources their mate offers. "According to the theory of evolved sex differences in jealousy (Buss, Larsen, Westen, and Semmelroth, 1992; Daly, Wilson, and Weghorst, 1982; Symons, 1979), ancestral women’s challenge of ensuring paternal investment exerted selective pressures that increased women’s jealousy in response to emotional infidelity, whereas ancestral men’s challenge of paternal uncertainty exerted selective pressures that increased men’s jealousy in response to sexual infidelity." |

"According to the theory of evolved sex differences in jealousy (Buss, Larsen,
Westen, and Semmelroth, 1992; Daly, Wilson, and Weghorst, 1982; Symons, 1979),
ancestral women’s challenge of ensuring paternal investment exerted selective pressures
that increased women’s jealousy in response to emotional infidelity, whereas ancestral
men’s challenge of paternal uncertainty exerted selective pressures that increased men’s
jealousy in response to sexual infidelity." Please note, this study seeks to address specific criticism of the theory of innate sex differences related to jealousy. It does not directly address the theory itself. How much of this behaviour is learned? In some societies jealousy is heightened as instanced by honour killings, including stoning and immolation. Even in developed, contemporary societies there are wide differences in the phenomenon of jealousy. The question may be addressed by cross cultural studies with past and present matrilineal societies; by looking at societies in which promiscuity is expected, at least at different stages of life; and by introducing as a situational variable, the learned concepts of the biological fact of paternity and of the varying paternal roles in child rearing (in some cases a maternal uncle fills this role). |

Only that the criteria in this instance is diametrically opposed to that predicted as being universal. The birds of paradise use different dances. The criteria may be different but they are used to signal the same thing or are used to accomplish the same thing. The Wodaabe males are showing off their strength and appearance to win women. |

Only that the criteria in this instance is diametrically opposed to that predicted as being universal. Broadly speaking, the EP prediction was that men are mostly interested in a woman's appearance and women are mostly interested in a man's capacity as a provider. Both the Wodaabe and your avian examples are diametrically different to that prediction. |

Au contraire. Women do seek traits and characteristics that reflect health and vitality in men as evidence of the genetic strength which signifies the ability to provide. It is common throughout the animal world (and we are part of that) for males to posture and compete. Much like that damned peacock.
