Not known Facts About dogs
Mitochondrial DNA indicates that nearly all modern dogs slide into one of 4 monophyletic haplogroups which are named haplogroups A, B, C, and D. Many dogs fall in haplogroup A. The mDNA "molecular clock" implies that 22,800 YBP the initial genetic divergence (break up) occurred in haplogroup A, leading to the lineages A1b and A2. This timing is the
