Male Chimpanzees Prefer Mating with Old Females
Martin N. Muller et al
"Cross-cultural studies indicate that women's sexual attractiveness generally peaks before motherhood and declines with age [1]. Cues of female youth are thought to be attractive because humans maintain long-term pair bonds, making reproductive value (i.e. future reproductive potential) particularly important to males [2, 3]. Menopause is believed to exaggerate this preference for youth by limiting women's future fertility [1, 4]. This theory predicts that in species lacking long-term pair bonds and menopause, males should not exhibit a preference for young mates. We tested this prediction by studying male preferences in our closest living relative, the chimpanzee (Pan troglodytes). We show that despite their promiscuous mating system, chimpanzee males, like humans, prefer some females over others. However, in contrast to humans, chimpanzee males prefer older, not younger, females. These data robustly discriminate patterns of male mate choice between humans and chimpanzees. Given that the human lineage evolved from a chimpanzee-like ancestor, they indicate that male preference for youth is a derived human feature, likely adapted from a tendency to form unusually long term mating bonds."
Klevius comment: How come that a scientific magazine approves such nonsense?! Ever heard abt kinship, kin recognition etc - the most essential relationship in the living nature? If the "research" team compared a chimp kin-society/family/group with a non-kin human dito, then not only their conclusion but the entire research project was pure nonsense! It's a well known fact (albeight today surprisingly surpressed) that most creature/plants have a strong tendency to avoid incest! Take a human kinship family and you will find a striking resemblance with chimps (albeit such an experiment would demand that both chimp- and human cultural bias/traditions somehow are taken into account)! This also explains why bio-parents are the least likely to commit incest as shown in Klevius revealing comparison of incest research as well as in the thesis "Pathological symbiosis" in the sex segregated social state.
