These DNA studies have been debunked for sampling bias. Essentially they only tested mummies from one location in northern Egypt that was known to be used by foreign occupiers like the Ancient Greeks during periods of non-native rule. And they didn't sample any remains from southern Egypt where the Pharaohs and Ancient Egyptian civilization as we know it originated.
It's sorta like if I tested the remains of graves in Harlem, NY during the Harlem Renaissance and said this proves that the Founding Fathers of America were of black African descent. It would be ludicrous.
Here's the AI breakdown of the study refuting the study you cited:
AI Overview
The Scheunemann et al. 2017 study, which analyzed ancient Egyptian DNA, has been criticized for its limitations in sampling methods, sample size, and the interpretation of comparative data. Specifically, concerns have been raised regarding the study's assertion that there was "no sub-Saharan genetic component" in the Egyptian population.
Here's a more detailed breakdown of the critiques:
- Sampling Issues:
The study focused on mummies from a single site in Middle Egypt, limiting its ability to represent earlier populations or those from Upper Egypt, which are geographically closer to Sub-Saharan Africa.
- Small Sample Size:
The 2017 study, while the largest on ancient Egyptians at the time, still relied on a small sample size.
- Biased Interpretation:
Critics argue that the study's authors may have biased their interpretation of the genetic data to fit their conclusions, particularly regarding the lack of a sub-Saharan genetic component.
- New (Untested) Sampling Methods:
The 2017 study employed a new, untested sampling method, raising concerns about its reliability.
- Problematic Comparative Data:
The comparative data used in the study were also questioned for their relevance and accuracy.
These criticisms have led some researchers to conclude that the Scheunemann et al. study's findings, while valuable, should be interpreted with caution and should not be taken as a definitive representation of the genetic history of ancient Egyptians.
