If it weren't for the association with malaria endemicity apparently attested in Africa and Europe, the pure gene evolution would point to a migration out of America (ancestral state) through East Asia to Europe and Africa (derived state). India is a bridge between the east and the West and a "swing" continent. Africa still preserves the original state in some pockets such as Madagascar, Horn of Africa and northwest Africa but overall it has shifted away from the original condition. <br /><br />But even with the malaria association in Africa and Europe this scenario would work.<br /><br />The map of Hbs distribution reminds me of Y-DNA YAP+ distribution, with Africa being heavy on YAP+ but with pockets of YAP-, Europe intermediary and Asia showing a strange small pocket of YAP+. India has Hbs, Tibetans and Andaman islanders have high frequencies of YAP+. America is devoid of YAP+ completely. There's a parallelism here, I think.German Dziebelhttps://www.blogger.com/profile/10703679732205862495noreply@blogger.com
