 Y-DNA was extracted from the same aboriginal Guanche samples used by Nicole Maca-Meyer et al., and compared to samples from 17th-18th century remains post-dating the Spanish conquest of the islands, and samples from the present population.They found Berber Y-chromosome lineages (E-M81, E-M78 and J-M267) prominent in the indigenous remains, confirming the North West African origin for the Guanches deduced Nicole Maca-Meyer et al.from mitochondrial DNA results.
