Two articles in PNAS caught my attention, Rapid dental development in a Middle Paleolithic Belgian Neanderthal & Life history trade-offs explain the evolution of human pygmies. Here are the abstracts:
Recent evidence for developmental differences between modern humans and Neanderthals…
Every few years a paper comes out "explaining" short stature in one or more Pygmy groups. Most of the time the new work ads new information and new ideas but fails to be convincing. This is the case with the recent PNAS paper by Migliano et al.

"Pygmy life expectancy is low, averaging 18 years and ranging from 15.6 to 24.2 years"
I had no idea of that.
It's the upper bound of the age range that's amazing to me.
Typically low life expectancy mostly has to do with very high rates of infant mortality.
It's often instructive to know what the life expectancy is for say 10 or 13 year olds. In the pygmy case it's got to be less than 24.2 years, which is rather amazing.
