all haplogroups are just subclades of their parent haplos. So R is just a specific variant of P that got spread around when Indoeuropeans raped a whole bunch of white wimminz. R, P, L, N, and O are all just haplogroup K--just very successful variants of it.

They don't "stop" evolving, for example haplogroup B will accumulate just as many mutations as haplogroup K2b. It's just that B was never expansive and successful, and didn't conquer loads of territory that its subclades became important clades of their own. BT was though, and all Euro/Asian men derive from this African male marker.

They have nothing to do with autosomal ancestry. They are very useful for tracing migrations and conquests because they never recombine, and also because male identity is always more telling than female identity (females always survive and reproduce, it's not very interesting)
