The first quick look revealed a pearl of citizen science using a large collection of Direct to Consumer […]


Ötzi the Iceman’s Y-haplogroup update

The power of citizen science unfolds by the comparison of public research data with thousends of DTC-test-results. In the case of Ötzi the Iceman the Y-haplogroup found in research papers as terminal is so far G2a2a1a2-L91/PF3246/S285 (b37 position 21645555 G->C). Ray Banks, the very active and skilled citizen scientist for Y-Haplogroup G has unveiled the […]
