In sexual behavioral biology, mammalian lordosis (Greek lordōsis, from lordos "bent backward") refers to the presentation of the "tail" with upward curved spine to signal receptivity to copulation found in many mammals. Scientists claim human lordosis is only a vestigial remnant of proceptivity-/receptivity-communicative signal between male and female, but eye-tracking reveals the arched back does catch both women's and men's attention, also explaining why women wear high heels as it optimizes the "lordotic" posture. Mammalian lordosis may have an even more ancient root in reptile behavior in which the female submits itself to the most dominant male. As such, lordosis is a behavioral disposition and reflex representing the quintessence of female submissiveness and passivity.
Yoga and gymnastics[edit | edit source]
Yoga seems to be full of postures, such as the Downward Dog Pose, that present the female lordosis posture and the crotch region. Human females appear to have a natural proclivity to present themselves in this manner.
Relation to whoring[edit | edit source]
In human evolutionary history they presumably often inappropriately presented their genitals in lordosis posture to obtain resources from males. In times of economic hardship women have been observed to display more lordotic behavior.
Sodomy and homocel hypothesis[edit | edit source]
As discussed in the homosexuality article, dominating the female in lordosis posture has been historically used to denigrate males as well, especially in honor-cultures and in prisons. It has been suggested, males can adopt the lordosis posture to get resources from other horny, bisexual males as a last resort (homocel hypothesis). This lead to male lordosis being depicted in satire, e.g. by Charlie Hebdo. Depicting lordotic males has been proven to be very offensive to some.
