Y-SNP calls from Mesolithic Scandinavia

In the table below are links to Y-SNP calls for DNA samples from Mesolithic Scandinavia.

    To samples from Hummervikholmen in Norway, dated 9452-9275 cal BP, came up with mito U5a1 (Hum1) and y-dna I2 (Hum2). Gunter et al, 2017.

    Can you check Motala2 sample if also belongs to I2c1 s6635?

  3. Bo S. Olsson says:

    Gunter et al claims the 9.000+ yrs old Hum 2 to be U5a1d and I2-M438, while their contemporary relatives buried at Stora Bjärs shows U4a1 and I2-M68.

    Then the 5.700+ yrs old Steigen comes up with U5a1d and I2a1b-M423.

    Any idea what caused the difference in y-dna, while the mt-dna-groups remained (seemingly) unchanged? Does that reflect an ‘evolutionary’ mutation of the y-dna, while the mt-dna remained more stable?!
