The researchers are explicit about this: more ancient Egyptian genomes from different sites and periods are needed to understand the range and distribution of ancestry profiles across Egyptian society.

And it certainly does not support any theory about ancient Egypt being populated or civilized by people from outside Africa.

The 80 percent North African Neolithic ancestry is the dominant component of NUE001’s genome, and it places him firmly within the genetic landscape of ancient North Africa — the descendants of the early farmers and herders who had inhabited the region for thousands of years before the pharaonic state emerged.

Ancient Egypt was an African civilization, built by people whose primary genetic heritage was African.
