Talk:Human Longevity and Gender Ratio/@comment-258494-20151219011331

This article is going to have to require serious re-working.

Environmental effects are only a tack-on effect to gender ratio; the larger issue is that the female gender has a biological advantage (the Double X hypothesis) which can be seen, for example, even with higher rates of mortality for male fetuses in the womb.

I'll take a further look at this article development soon.Ryoung122 (talk) 01:13, December 19, 2015 (UTC)
