There's an enormous difference between Africa and the Caribbean due to the fact that the Caribbean has no autochthonous population.

All of its people are immigrants, either from the top of the society, the youngest sons, and so forth; or blacks who were brought there through the slave trade. The only autochthonous population, the Caribs, has completely disappeared.
