the data indicate that about 99 percent of all humans measured have duplications in the salivary amylase gene at least one duplication if not you know five six seven duplications the more there's a history of starch eating in that group the more duplications there are but even when there's no known historic contribution of starch to the diet those duplications are still there they're not found in any of the other Apes except bonobos who have but there's a inactivated and they're not found in the end their falls are not found in Denisovans so my impression from that is like no one knows when the salivary amylase gene was duplicated but I think that data indicates that if it's so almost Universal among all humans from very disparate ancestry for example like when was the last time that a European had common ancestry with like a hodza you know we're thinkin common ancestor in that area it's clearly after we split off from the other Apes it's clearly after we split off from the Endor thousand and Denisovans but it's clearly before the most recent common ancestor of all humans that have been measured
