Ancient DNA from rare fossil reveals that polar bears evolved recently and adapted quickly (3/4/2010)

Ancient DNA from rare fossil reveals that polar bears evolved recently and adapted quicklyDNA 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 pieces of the evolutionary history of both polar bears and brown bears. The fossil's DNA is, by far, the oldest mammal mitochondrial genome to be sequenced -- about twice the age of the oldest genome sequence from a woolly mammoth. ...> Full Article


An answer to another of life's big questions (2/6/2010)

Monash University biochemists have described the process by which bacteria developed into more complex cells and found this crucial step happened much earlier in the evolutionary timeline than previously thought. ...> Full Article



DNA testing on 2,000-year-old bones in Italy reveal East Asian ancestry (2/3/2010)

DNA testing on 2,000-year-old bones in Italy reveal East Asian ancestryResearchers excavating an ancient Roman cemetery were surprised when DNA testing on a set of bones revealed East Asian ancestry. ...> Full Article



Wild Iberian horses contributed to the origin of the current Iberian domestic stock (1/9/2010)

Wild Iberian horses contributed to the origin of the current Iberian domestic stockSome modern horses of Iberian origin are descendants from wild horses from the Early Iberian Neolithic, dated around 6,200 years ago. Ancient lineages are mainly represented in the Lusitano group C, constituted by some modern Lusitano and American horses. This is one of the conclusions obtained by a researchers' team from Spain, Sweden and Denmark and published in Molecular Ecology. ...> Full Article

Ancient penguin DNA raises doubts about accuracy of genetic dating techniques (11/16/2009)

Ancient penguin DNA raises doubts about accuracy of genetic dating techniquesPenguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent. ...> Full Article

Scientists present the largest-to-date genetic snapshot of Iceland 1,000 years ago (1/18/2009)

Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors. The study is published Jan. 16 in the open-access journal PLoS Genetics. ...> Full Article


Woolly-mammoth gene study changes extinction theory (6/11/2008)

Woolly-mammoth gene study changes extinction theoryA large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity. ...> Full Article

Mitochondria Regulates Cellular Copper Levels (5/6/2007)

Copper is an essential part of our lives. From copper pipes and wires - to important copper-containing proteins in the body, copper is necessary for healthy growth and neurological development. Researchers at the Montreal Neurological Institute at McGill University are studying how copper is processed in our bodies and its distinct role in early development. ...> Full Article
