If this were true... the Senju would not have been the strongest clan. And there would be more than TWO clans rivaling if all of the descendents directly after the brothers werent Senju and Ulchiha.

Uzumakis could be descendants from a third line, a third son/daughter that SO6P had.I think some of you are misunderstanding the concept of the sons and SO6P.
The Uchiha and Senju are the decendents of the SO6P's sons. So the sons could not have been Uchiha and Senju. They could have been called something else and down the line after all the ages and decendents it ended up being the Uchiha and Senju.
Now this is where the Uzamaki come in. There obviously wasn't only one clan (Senju) that were the decendents, same as the Uchiha they weren't the only clan that were the decendents.
So in conclusion it's not neccessarily true that the Senju was first or the Senju has the stronger body or physical energy. (This hasn't been exactly stated in the manga, so this would still end up as just being a theory, but I'm 98% sure this is what the manga is implying)
Ummmmmmmmmmmmmm no the Uzamaki was there way before Hashirama. Mito was Uzamaki so what is she his daughter and his wife??I had a thought today about how the Uzumaki's came to be. We know they are related to the Senju but how so? While i was reading the manga and seen the rebirth regeneration technique it made me wonder. Did Hashirama teach it or perform it on a woman of the Senju clan who was giving birth and thus the longevity and possible special chakra from hashirama's technique??? Just a guess
