Lichtenstein Cave Data Analysis
Any type of content formally published in an academic journal, usually following a peer-review process.
Felix Schilz reported in his PhD Thesis [May 2006, http://webdoc.sub.gwdg.de/diss/2006/schilz/schilz.pdf] DNA analyses of ancient skeletons found in the Lichtenstein Cave of the Harz mountains in central Germany. Since this important information was at the time not available in English, the author wrote an English summary of it in March of 2008. This summary focused on the data of his thesis which is relevant to Genetic Genealogy.
