Sure women probably hunted, but claiming there is no evidence for a "sex-based division of labor" is hogwash. Some hunted the same game as men, some probably other prey. Some probably gathered food depending on their child status and physical capabilities. The article focuses much on the advantages women are provided due to estrogen. Sure for some activities (like child rearing) and general health the female hormones make sense. But, I have yet to see any athlete in any sport (including ultra marathon) taking estrogen for an advantage. Willing to be proven wrong.
