They are the only traditional hunter-gatherers indigenous to Zimbabwe and are famous for the inherited ectrodactyly existing among some vaDoma families at much higher rates than typical globally.
This may refer to Khoisan hunter-gatherers who preceded the migration of the Bantu Shona into the Zambezi Valley, and the vaDoma are possibly related to this earlier population.
[6] Prior to the European colonization of Africa, the vaDoma also resisted incorporation into the Korekore Shona kingdom of Mutapa,[3] which resulted in little access to fertile land.
While possibly an aid in tree climbing, the condition prevails because of a small genetic pool among the vaDoma and is propagated by the tribal law that forbids members to marry outside the group.
[2] Due to the vaDoma tribe's isolation, they have developed and maintained ectrodactyly, and their comparatively small gene pool has resulted in the condition being much more frequent than elsewhere.
