BSCI 222 Lecture Notes - Lecture 17: Nuclear Dna, Bantu Languages, Lactase
Document Summary
Certainty vs probability: firm belief vs scientific likelihood. African populations have lived in their native continent for longer than any other indigenous populations in other continents. Phylogenetic tree shows the l branches and their relationships to each other and to the m & n. Bantu language arose 3000-5000 ya in cameroon. They developed agriculture and had defined languages: these were the farmers who evolved lactase persistence in africa, because of mixing and migrating has been hard to distinctly define, but they are not usually l0 of l1. They moved physically to other parts of africa, taking their languages, agriculture, and dna with them. Yes, but only in conjunction with historical records. Haplogroups-remember haplogroups are stretches of dna that tend to be inerited as a block. Autosomal-some stretches of nuclear dna inherited as a block.
