Plants and insects of a boreal forest estimated to be between 450.

Ancient DNA suggests earth was warmer than previously believed A team of international experts has collected the oldest ever recovered DNA samples and used them showing that Greenland was very much warmer at some time over the last Ice Age than a lot of people have believed. The historic DNA was discovered in the bottom of a two kilometer thick ice sheet and came from the trees, plants and insects of a boreal forest estimated to be between 450,000 and 900,000 years-older here . Previously, the youngest proof a boreal forest in Greenland was from 2.4 million years ago. The results of the research were released today in the journal Science. These findings allow us to produce a more accurate environmental reconstruction of that time period period from which these samples were taken, and what we’ve learned is that this section of the globe was considerably warmer than a lot of people thought, said Martin Sharp, a glaciologist at the University of Alberta and a co-writer of the paper.

Notably, the team also discovered that genetic disruption of the framework of this fiber prevented effective replication taking place in T. Gondii. These altered parasites can initially infect cells, but after we turn off the fibers genes, they can not create new child spread and cells, explained study author Maria Francia, from the University of Georgia, Athens, USA, in a press statement. Because it cannot replicate, the parasite eventually dies without causing severe harm.
