I dunno why you're asking this question because I suspect you prolly already know the answer! Our ancestors did OK without any high GI carbs, and some on very low overall carb diets. I think the answer lies in what kind of carbs you eat and when. It is now recognized that even the most hard-core low carbers (such as the Inuit) got a significant amount of glycogen and vitamin C from the livers of the seals, whales, polar bears and fish that they ate (RAW). Others of our ancestors that lived in more temporate climates had long hard winters as well, and hung out like crazy for the fruits of summer and autumn as well as going to incredible lengths to get stuff like honey from bee hives. To fill in their empty stomachs they ate vegetation. Overall it appears that carbs have always been sought by our ancestors, especially sugars, but these were rare and hard to get a lot of except dring short periods of plenty when we no doubt 'fattened up' to ensure reproduction and survival through the next hard time. Carb cycling used sensibly (low GI, low insulogenic ones) will no doubt be close to what our ancestors thrived on. Dr. Mauro DiPasquale, etc....seem to be addressing the hormonal benefits from a male perspective (please correct me if I'm wrong) and also use some form of carb cycling. As far as I know, women's hormonal response to a very low carb diet is different to mens. It cannot increase natural testosterone production in the same way, and will more likely increase female hormones (estrogen, progesterone etc..).
High carb/high GI diets are very tightly linked to female hormonal disorders such as PCOS, acne, hirsutism and other conditions that are directly linked to insulin's ability to increase TESTOSTERONE levels (in males AND females). Unfortunately most women (and men) also get pretty fat when their test AND estrogen levels are high. So if you want to try a high carb diet for gaining mass, I recommend some kind of antiestrogen.
