These are neat findings. Apparently Pastoralism (animal herding) began in the Fertile Crescent and migrated through ancient Egypt (roughly around the time of the early kingdoms) and migrated into subsaharan Africa—a slow process where cattle (generic) were exchanged and traded but people, so far it seems, didn’t intermix as much as one would think.

It’s only scratching the surface; the ancient DNA data for the region is sparse, but it’s slowly contributing to a better picture of how people and animal husbandry spread across continents, among other things.
