Two separate incidents in a span of three weeks show how scientists who hype up and sensationalise their work end up diluting the significance of their discovery. In a paper published online in the Science journal in the first week of December … Continue reading Editorial: Hyping up science
Published in The Hindu on May 15, 2010 Did Neanderthals and modern humans interbreed? While several methods, including the study of mitochondrial DNA of Neanderthals, failed to resolve this longstanding controversy, a comparison of the genomes of Neanderthals and modern humans shows that between 1 and 4 per cent of the DNA of humans living … Continue reading Editorial: Neanderthal genes in us
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
Published in The Hindu on February 25, 2009 The successful completion of a rough draft of the Neanderthal genome — this is the first time that a genome of an extinct organism has been sequenced — marks a giant leap in evolution science. The announcement coincided with the 200th birth anniversary of Charles Darwin. The … Continue reading Editorial: A giant leap in sequencing Neanderthal genome
Published in The Hindu on February 19, 2009 Preliminary study of the Neanderthal genome reveals many thousands of differences between the two closest relatives The genetic makeup of chimpanzees and modern humans differ by only 1 per cent. And in the case of Neanderthals, the difference is as small as 0.5 per cent. The rough … Continue reading Unlocking the secrets of human evolution
