Razib thinks (but isn't certain) that King Tut's Y haplogroup is the IE R1b, not the Chadic R1b. One of King Tut's male line ancestors was a 16th century warlord who was later portrayed as a hero of Egypt against Hyksos foreigners: en.wikipedia.org
Per his line of thought, an IE group (probably a branch of the Aryans, maybe but less likely Armenians or Hittites) introduced better horses & chariots to Middle East, most famously as Mitanni. Somehow one group of them, or maybe even an individual, got in with the Hyksos.
then that family/group/clan/etc descended from the IE guy/guys built a power base in Thebes and warred with the other Hyksos & founded what became the 17th and 18th Dynasties of Egypt, their origins later being whitewashed as being Egyptian rather than as foreign.
fabricated family trees and national origins weren't uncommon in history. The ruling family of medieval Russia, the Rurikovichi, has been confirmed by medieval DNA to have at least some fraudulent branches. Vladimir the Great's story also sounds really suspicious imo.
