Whoopi Goldberg, like many others, is turning to DNA testing to learn more about her ancestry. Goldberg participated in the PBS program African American Lives which used DNA testing in conjunction with traditional genealogical research methods to elucidate the genealogy of famous African Americans (including, among others, Goldberg, Oprah Winfrey, and Dr. Mae Jamieson). The results of Goldbergâ€™s mtDNA testing has revealed that her maternal line descends from the Papel and Bayote tribes who are found in the tiny West African Nation of Guinea-Bissau. Her admixture test suggested that her ancestry was 92% sub-Saharan African and 8% European.As with all DNA testing, Goldbergâ€™s results only examined a small fraction of her actual ancestry.

MITOMAP Publishes an Updated mtDNA Phylogenetic Tree
MITOMAP, the human mitochondrial genome database, has recently published a paper in Nucleic Acids Research (Free Full Text Here) announcing the completion of a full human mtDNA phylogenetic tree.
This tree, available here(pdf) was constructed from 2959 mtDNA coding region sequences (using the rCRS as the reference).In addition to listing mutations and the study that identified each particular sequence, the tree labels each mutation as a substitution mutation, a silent mutation, a tRNA or rRNA mutation, a mutation in the noncoding region, or a pathological mutation.MITOMAP also provides another valuable tool, tables of mtDNA polymorphisms with source information.
The tree will potentially be very useful to both researchers and genetic genealogists by providing a quick and easy way to characterize new sequences.Anyone interested in learning more about their haplogroup or how their haplogroup fits into the human mtDNA tree will find the new mtDNA phylogenetic tree extremely informative.
New estimates for the arrival of the earliest Native Americans
Scientists have analyzed the mitochondrial and Y-chromosomal DNA from a 10,300-year-old human remains found in On Your Knees Cave on
DNA sequencing showed that the individualâ€™s mitochondrial DNA belongs to an ancient subhaplogroup of haplogroup D that was brought to the
