Women’s wide hips

According to the article cited below, women’s wide hips do not mean inefficient locomotion. The author also seems to be arguing that childbirth does not require wide hips. So, why wide hips? I am wondering if it is something to do with the strength and/or stability of triangles (such as that made by a wide pelvis and the legs) and the way women need to carry babies and young children efficiently, with the downward force towards the ground.

Stability might be particularly important when carrying a baby or child because of the risk of injury to the young.

This includes several interesting essays including some thoughts on benign patriarchy. I believe we currently have a benign patriarchy in the West, which should be conserved.

James Doyle on lordosis in women

 

Lordosis?

The emphatic curve in these ladies’ backs, making their buttocks more prominent, resembles lordosis. Wikipedia considers whether this ancient mammalian posture has a role in humans here.

I have written at this blog about why certain female body parts have such appeal for men. In reflecting on female legs, my feeling was that heels work mainly by accentuating curves. I wonder if the real fundamental “sexual releaser” for men might simply be curves. In lordosis. With breasts. With legs …

Are long, gentle curves the most attractive? Like the Eiffel Tower:

I am not sure if the girl below shows the blue skin effect, but I include her because she is rather lovely:

Another woman with skin so dark it looks blue?

I have written about this blue effect and its possible relationship to the optical “Tyndall effect” here.

Did Low Ultraviolet Light in Their Rainforest Environment Cause the Dwarfing of Flores Man (Homo floresiensis)?

I spent a lot of time last night thinking about Flores Man (the “hobbit”). Why were these people so tiny? One theory is that it was a case of “island dwarfing”, due to limited resources on an island, although Flores is not really that small an island – it’s bigger than Jamaica and the big island of Hawaii.

It now seems to be accepted that Homo floresiensis (the “hobbit”) was derived from a population of Homo erectus that founds its way to Flores.

It also seems to be accepted that Homo erectus likely had dark skin.

Dark-skinned humans that move into rainforests typically become dwarfed (Pygmies and Negritos). Years ago, I suggested that this is due to the shortage of ultraviolet light under the rainforest canopy to make vitamin D in human skin. Vitamin D is needed for calcium uptake and bone growth. (It seems to be accepted that Homo erectus needed vitamin D, like modern humans.)

I have put a copy of this note for discussion at Academia.edu
