The mitochondrial tree of humanity has been rewritten, connecting all of us more closely than ever before on the new Mitotree. Everyone receives mitochondrial DNA only from their mother, who receives it from her mother, and so forth, all the way back in time to Mitochondrial Eve. Mitochondrial DNA is never admixed with the DNA of the other parent, so you never have to sort out which lines it comes from. We are all leaves on the twigs on the branches of the tree of humankind. The mitochondrial tree had not been updated since 2016, but now, with more than a Million samples to work with, 50 times more than before, the tree structure has been expanded eight-fold by combining samples from academic publications, ancient DNA, public sources and testers at FamilyTreeDNA. The new Mitotree and tools provide information never before available to genealogists about their matrilineal lineages. In addition to the vastly expanded genetic tree, FamilyTreeDNA has rolled out the companion MitoDiscover, a dozen fascinating chapters in your mitochondrial book. As a Million Mito Team member, Roberta will explain the challenges we overcame to create the tree of humanity – and how it’s useful to genealogists. All genealogists can benefit from the results of the Million Mito Project, because everyone has mitochondrial DNA that holds keys to information never before available! Let those brick walls fall!!!
