Assistant professor Mikkel W Pedersen said there was 'no present-day equivalent' for the ecosystem from which the DNA dates back
Forty-one of the Ice Age-era samples discovered were useable for the scientists' research.They had to be detached from the clay and quartz in which they were buried, having been preserved by ice or permafrost and - crucially - undisturbed by humans.
That's how they were able to find evidence of predecessors of species we know today, building a picture of a previously unknown stage in the evolution of many that still exist. The DNA's survival through changing environmental conditions is the most striking feature of the discovery. He added:"On the face of it, the climate seems to have been similar to the climate we expect on our planet in the future due to global warming."

Flipping the switch: Scientists shed new light on genetic changes that turn 'on' cancer genesCancer, caused by abnormal overgrowth of cells, is the second-leading cause of death in the world. Researchers from the Salk Institute have zeroed in on specific mechanisms that activate oncogenes, which are altered genes that can cause normal cells to become cancer cells.
