Is there any "uniform culture?" -- LOL
No, it's built around enslaved Africans who were sold into slavery and enslaved in America -- and who they and their descendants -- had to create their own culture.
Drawing from influences from their ancestors no? It’s why African Americans eat okra and Jamaicans eat ackee, it’s funny because Jamaicans will argue their not Africans while having a quarter of their newly formed dialects patios derive from various African languages, what makes Ados unique is that, you had African slaves from different parts of the west and centre come together as one new people..
But this isn’t even a new thing, if we want to be truly pedantic, yorubas igbos you name it can boast of the exact same thing if they truly knew their history, Akans eat jollof rice from Senegal and wear Nigeria inspired garments, all groups have links with mali and Timbuktu, migration and amalgamation of cultures and ethnicities amongst even west Africans isn’t new, so your point about trying to separate and establish Ados as a whole separate entity is a fair one, but how long can it last, black gravitate and borrow from other blacks, so the Jamaican American biggie smalls becomes the biggest rapper in the world, 20 years later the Canadian American drake does the same, who really cares, when it comes down to it?
