>>11099099>by that example you mean to say there is a fairly recent genetic relation of those people in china with those native australians.Not necessarily recent, and the place with the highest concentration of a Haplogroup isn’t necessarily where it originated because humans have migrated all over the damn place.
> 1. what do the names mean (e1b1a1 etc.)?I’m not really sure how they do it, but I think they go by order of descent, with Haplogroup A being the oldest one and all the others descending from it. It’s complicated.
> 2. what important application could this have outside of shitposting on 4chan?It tells us things about potential vulnerability to disease, history of human migration, and ancestry which lots of people find interesting.
> 3. you said this indicates descendance from a specific person, family, group etc. but what happens when they marry other groups? are new haplogroups created, do we call it a combination of two haplogroups?You can only have one Y-chromosomal Haplogroup because=
1. Only human men have Y chromosomes, and they only have one.
2. Men only reproduce with women, who have no Y chromosome.
