re: Prehistoric women were probably better at hunting than men, scientists suggest

Their point is that estrogen helps in extreme endurance competitions like ultramarathons, therefore it must have been useful in persistence hunting situations. BUT… what sort of hunting expedition chases prey for hundreds of miles so that estrogen becomes an advantage, a la ultramarathon?

And the study really does just brush aside the fact that a woman back then was likely pregnant every year of her adult life. How could they spend all that time bringing home the bacon, literally… in that condition year after year… more so than the men?
