Well... here we are, I guess! Just submitted my PhD and it feels pretty unreal! So proud of this journey!
More exciting data on the Nile Valley is coming, plus some new projects to announce soon.
Stay tuned, this adventure is far from over! 👀

We also discovered evidence of mobility along the Wadi Howar river during the Neolithic period: some individuals from the desert show a "Nilotic-like" signal, while individuals from the Southern Dongola Reach (along the Nile) show a forager/desert-like ancestry - suggesting regional exchanges.🚶♂️🚶♀️

Interestingly, while the new food-producing population replaced the previous hunter-gatherers along the Nile, we identified a forager-related population in the Eastern Sahara.
This suggests that Neolithic newcomers did not extend further into the desert margins and settled along the Nile only.

We found significant morphological differences between the last foragers and first food-producers in the region.
Considering the extremely high phylogenetic signal of the EDJ, this provides clear evidence of biological discontinuity and migration towards the valley at the Neolithic transition 🔄

We analyzed the enamel-dentine junction (EDJ) -a highly reliable proxy for population affinities- of 88 individuals from Late Pleistocene to mid-Holocene sites in Sudan and Southern Egypt. We focused on the first and second upper molars of these individuals. 🦷
