And some of them dating back 30K years or so.<br /><br />It was Y-DNA wich had always been a problem. And until "recently", one had to be extremely lucky to extract Y-DNA from something that is older than 2K or so years.<br /><br />A reason why there was so few ancient y-dna.<br /><br />It apears that methods of extraction have extremely improved. So that now, its possible to estaminate Y-DNA or even autosomal DNA under corpse conditions, in wich it was impossible 3 or 4 years ago.<br /><br />And since then, ancient Y-DNA or autosomal DNA data comes in "frequently".Fantyhttps://www.blogger.com/profile/07969348276219179258noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-4024996216093672792012-04-25T12:30:18.874+03:002012-04-25T12:30:18.874+03:00Not an expert, but clearly it depends on the state...Not an expert, but clearly it depends on the state of conservation - mostly influenced by temperature but also soil conditions etc. Farther north it's almost done routinely, now, for that time period and earlier - especially concerning mtDNA, but also y-haplogroup determination.<br /><br />http://www.buildinghistory.org/distantpast/ancientdna.shtmleurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-84101732482141669902012-04-25T01:34:30.722+03:002012-04-25T01:34:30.722+03:00I have a layperson's question for those who ma...I have a layperson's question for those who may know - has the science and technology for testing ancient DNA advanced to the point that archeologists are able to test late neolithic bone samples? I recently read up on the "death pit" at Domuztepe in Turkey and wondered if such testing there could shed light on neolithic farmer migration from that area into Europe.Mark Dhttps://www.blogger.com/profile/03792117663748801194noreply@blogger.com
