Origin of Uchiha and Hyuuga Clan

Takl "it's said that the origin of the Uchiha clan can be traced back to the huga clan.
Byakugan is a kekkeigenkai that has been inherited in the hyuga family and a dohjutsu similar to(/like) sharingan but..."
"when it comes to penetration ability
its the stuff that is even superior than sharingan."

「うちは一族も元をたどれば日向一族にその源流があると言われている ”百眼”ってのは日向家の受け継いできた血継限界の一つで写輪眼に似た瞳術だが... 洞察眼の能力だけなら... 写輪眼をもしのぐ代物だ」
"Uchiha Ichizoku mo moto o tadoreba Hyūga Ichizoku ni sono genryū ga aru to iwarete iru. 'Byakugan'tte no wa Hyūga-ke no uke tsuidekita Kekkei Genkai no hitotsu de Sharingan ni nita dōjutsu da ga... Dōsatsugan no nōryoku dakenara... Sharingan o mo shinogu shiromono da." 

"It's said that if you follow the Uchiha Clan further to its origins, it would be (where) the Hyūga Clan (is located... or so). The "Byakugan", one of the Hyūga house's Kekkei Genkai passed on by inheritance, is similar to the Sharingan - a Dōjutsu. Only when it comes to the power of insight... these are goods that even surpass the Sharingan."
