In 1991, German tourists in the Alps discovered the mummified remains of a man who died approximately 5,000 years ago. Named Ötzi, the remains have been studied extensively and have revealed a wealth of information about life in this region.
Of note to genetic genealogists, Ötzi’s DNA has also been the subject of extensive analysis. In February 2012, sequencing of Ötzi’s full genome was announced (see here and here) which revealed, among other things, that the Iceman probably had brown eyes, belonged to blood group O, and was lactose intolerant. He may also have had Lyme disease, as the genome of the infectious agent Borrelia burgdorferi was also identified in the sequencing effort.
Ötzi’s Y-DNA belongs to a subclade of Haplogroup G defined by the SNPs M201, P287, P15, L223 and L91 (G-L91). As far as I know, he has not yet been typed for any of the subclades downstreaming from G-L91. More information can be found at the G-L91 page of the Haplogroup G Project, and elsewhere online. ...
