Talk: Obstetrical dilemma--or--changes in the conformation of the pelvis
Why is the obstetrical dilemma put as an afterthought and so hard to find? If I didn't already know about it I wouldn't have known to look for it! (..And I was about to refer someone to Wikipedia about this--but obviously not yet). The change in the conformation of the birth canal is absolutely essential to an understanding of how Homo sapiens developed. The birth canal narrowed with bipedality at a time when the brain was increasing in size. Understanding post-natal brain development in primates is important; in humans it is absolutely essential. In human infants the brain doubles in volume in the first year and then continues to increase, especially the "social brain" (I can't remember the scientific term but you can quickly find it in Sue Gerhardt--Cradle of Civilization published by the Guardian within the last 10 years and still online). Some comparative illustrations of pelvi--Lucy, Chimp, Homo sapiens--would make it much clearer. Sorry I didn't take the time to sign in. Margaret9mary.

Interesting new evidence suggests that metabolism is the primary factor behind this conundrum
I'm new to editing wikipedia but added a small edit with reference to a study that suggests this theory may be obsolete. I suck at this apparently and me reference link isn't properly annotated. If someone is willing to fix it or point me in the proper direction for future edits I promise to not leave a mess behind. A bit too busy tonight to spend more time on it right now though.

Adding to the page
This article seems to be missing a lot of information. I think that neonatal rotation in humans is important to understanding the obstetrical dilemma and how other non-human primates do not have neonatal rotation. Also, there are other adaptations to solve the obstetrical dilemma that aren't covered such as assistance in birth and malleability of the cranium. Tanyamcamper (talk) 04:14, 9 October 2013 (UTC)
