Published in The Hindu on April 10, 2010 Nearly 10 years after the genome of a living individual was first sequenced, and shortly after the sequencing of the genome of a 4,000-year-old male Eskimo, scientists have successfully sequenced the mitochondrial DNA (mtDNA) genome of a nearly 40,000-year-old hominin. The study, published recently in Nature, was … Continue reading Editorial: A new human species

Published in The Hindu on March 25, 2010 A team of scientists has successfully sequenced mitochondrial DNA (mtDNA) of a hominin who had lived in the Altai Mountain region of Siberia, Russia. This hominin had shared a common ancestor with anatomically modern humans and Neanderthals about 1 million years ago. Further investigation reveals that the … Continue reading New species in human’s family tree found
