Where did the ninja clans other then Senju and Uchiha originate from?


In the anime, it is shown that the Senju and Uchiha clans originated from the
Sage of Six Paths who is the God of Shinobi. Where did the other clans like
Sarutobi, Nara, Inuzuka, clans from other countries originate from?




Recall that the Sage of the Six Paths discovered the existence of chakra and
used it to create jutsu. The direct descendants of him became Senju and
Uchiha, where their powers were split between body and eye.

Other ninja clans were not descendents, however they were able to learn how to
use chakra as well in different forms of jutsus. Of course there are some
clans, like the Hyuuga where the series notions the possibility of them
deriving from the Uchiha.

Clans like Sarutobi, Nara, and Inuzuka clans are not related to the Sage of
Six Paths though. On the other hand, Uzumaki is blood related to Senju.
