Complete mtDNA phylogenetic tree of haplogroup H6.

<p>The schematic tree is based on phylogenetic tree presented on <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054360#pone.0054360.s002" target="_blank">Figure S2</a>. Time estimates (in kya) shown for mtDNA subclades are based on the complete genome substitutions <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054360#pone.0054360-Soares2" target="_blank">[42]</a>. The circle size is proportional to the number of individuals sharing the haplotype. Geographical origin is indicated by different colours: green - central and eastern Europe (Czech Republic, Poland, Russia, Slovakia, Ukraine); yellow – southern Europe (Italy, Spain); red – western Europe (Austria, Germany, Netherlands); blue – northern Europe (Denmark, Finland, Ireland, United Kingdom, Orkney Islands); black – Near East (Israel, Jordan); grey – America (Philadelphia); white - unknown origin.
