آدم سے پہلے کے حیوانی انسان کہاں گئے ؟؟
Are you tlaking about homo genus? If yes, there is evidence of their extinction. We know before humans there were homo erectus and homo neanderthals etc. modern humans are only surviving specie of homo genus. How they got extinct, it is disputed topic though. Neanderthals are reported to be alongside homosapiens for sometime.
I recently published an article which might answer this question: http://www.monthly-renaissance.com/issue/content.aspx?id=38790
