Hello. This is my opinion on how the power got split from Kaguya into following generations.

Many people believe, because of Orochimaru and Kabuto's hypothesis that Rinnegan is an evolution of the Sharingan. First, they were operating under the notion that Uchiha powers + Senju powers = Rinnegan, but they were only partially correct, because it has to be Asura's + Indra's chakras, which they didn't know.

I disagree with this common notion. In my opinion, the Sharingan and Rinnegan are two separate, but related doujutsu. I see it differently why the Rinnegan surfaces when Asura and Indra's chakras are combined.

If it were true that the Rinnegan is an evolution of the Sharingan, then it should be enough for any Uchiha like Itachi, Shisui etc. to just get Asura's chakra for the Rinnegan, but it doesn't work that way, so the Sharingan DOESN'T evolve into Rinnegan.

This is how I see it. The Sharingan is part of Indra's chakra and Indra's descendants inherit fragments of Indra's chakra thus have a chance to inherit the Sharingan.

The reason why combining chakras of Asura and Indra creates the Rinnegan is obvious, it's because the two chakras mixed together equal Hagoromo's chakra, who possessed the Rinnegan.

But if I'm saying that the Sharingan doesn't evolve into Rinnegan and Indra got the Sharingan... you might be asking where does the Rinnegan part come from. 'Asura's chakra? But Asura had no Rinnegan!' might be what you are thinking and you are correct.

The way I see it, the Sharingan went to Indra's part of chakra, while the Rinnegan went to chakras of both Indra and Asura.

What I'm saying is that Sharingan is part of Indra's chakra, while Asura's chakra is Hagoromo's 'body' but both of them also have one half of the Rinnegan. Simply put:
 * Indra's chakra = Sharingan, 50% of the Rinnegan
 * Asura's chakra = Hagoromo's body, 50% of the Rinnegan

Thus that's why combining the two recreates the Rinnegan, meaning the Sharingan in Indra's chakra doesn't evolve into the Rinnegan, rather Indra has parts of the Rinnegan in his chakra while Asura's chakra has the remainder of the Rinnegan.

So since my claim that the Sharingan and Rinnegan are two separate, but related doujutsu, this is how I see it went down:


 * Kaguya eats chakra fruit, gets Rinne Sharingan as 3rd eye on forehead
 * Hagoromo not having 3rd eye on his forehead, instead inherits power of the Rinne Sharingan split between his two ordinary set of eyes, as a pair of Sharingan and a pair of Rinnegan
 * Indra inherits Sharingan and half of the Rinnegan
 * Asura inherits body and half of the Rinnegan
