Genetic Footprint of Natural Selection
March 2, 2010 A further step has been taken towards our understanding of natural selection. Scientists in France have shown that humans, and some of their primate cousins, have a common genetic footprint -- i.e., ... > full story -
Ancient DNA from Rare Fossil Reveals That Polar Bears Evolved Recently and Adapted Quickly
March 1, 2010 DNA from a rare, ancient polar bear fossil is yielding information about the response of the species to the devastation wrought by past climate changes. Analyses of the fossil's DNA reveals key ... > full story -
By Tracking Water Molecules, Physicists Hope to Unlock Secrets of Life
February 27, 2010 The key to life as we know it is water, a tiny molecule with some highly unusual properties, such as the ability to retain large amounts of heat and to lose, instead of gain, density as it ... > full story -
DNA Sequence of Extinct Ancient Cattle Uncovered
February 27, 2010 Researchers, based in Ireland and Britain, have found the complete mitochondrial DNA genome sequence of ancient wild cattle using a sample from a 6,700 year-old ... > full story -
Stickleback Genomes Shining Bright Light on Evolution
February 25, 2010 Twenty billion pieces of DNA in 100 small fish have opened the eyes of biologists studying evolution. After combining new technologies, researchers now know many of the genomic regions that allowed ... > full story -
Interactions Between Species: Powerful Driving Force Behind Evolution?
February 25, 2010 Scientists in the UK have provided the first experimental evidence that shows that evolution is driven most powerfully by interactions between species, rather than adaptation to the ... > full story -
Small Dogs Originated in the Middle East, Genetic Study Finds
February 23, 2010 A genetic study has found that small domestic dogs probably originated in the Middle East more than 12,000 years ago. Researchers have traced the evolutionary history of the IGF1 gene, finding that ... > full story -
DNA Sequencing Unlocks Evolutionary Origins, Relationships Among Flowering Plants
February 23, 2010 The origins of flowering plants from peas to oak trees are now in clearer focus. A new study unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of ... > full story -
Ancient DNA Reveals Caribou History Linked to Volcanic Eruption
February 22, 2010 DNA recovered from ancient caribou bones reveals a possible link between several small unique caribou herds and a massive volcanic eruption that blanketed much of the Alaskan Yukon territory in a ... > full story -
Scientists Create Tiny RNA Molecule With Big Implications for Life's Origins
February 22, 2010 An extremely small RNA molecule created by scientists can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward ... > full story
