Denisovans & Modern Humans Introgressed At Least Twice

Sharon Browning and colleagues published a paper in Cell last week that shows there are uniquely different Denisovan genomes in the DNA of East Asian individuals, indicating that interbreeding with Homo sapiens happened in two independent episodes. See we already knew Aboriginal genomes from Australia and Papua New Guinea contain fragments of Denisovan DNA. Introgression of... Continue Reading →

The Diversity of the African Genome & Traces of an Unknown Hominin

The most comprehensive look at the genome of Africans is published in the journal Cell today. The paper titled, "Evolutionary History and Adaptation from High-Coverage Whole-Genome Sequences of Diverse African Hunter-Gatherers," focused on three hunter-gatherer populations; Pygmies from Cameroon and two groups from Tanzania, the Khoesan-speaking Hadza and Sandawe. The publication covered each of the genomes of five... Continue Reading →

Complete Denisova Genome Released

We've covered the mitochondrial genome of the Denisova individual 2 years ago, back in March 2010. For those not familiar with the Denisova hominin, this specimen represents an archaic human species present at least 41,000 years ago - coexisting with Neandertals and modern humans in the Altai Mountains of Siberia. The species is represented by a tooth and phalange. A draft... Continue Reading →

The Neandertal Draft Genome

Every time big anthropology news has come out in the last year or so, I'm too busy and drowned under the sea of books and notes for my upcoming exams to immerse myself in it. This happened with Ardipithecus last fall, and now with the draft of the Neandertal genome coming out tomorrow, I can't... Continue Reading →
