a bitterly cold and inhospitable climate, today large parts of north greenland are harsh polar desert, but a new discovery suggests it has not always been so bleak. scientists have been able to turn back the clock two million years to be precise and have found evidence of thriving life. two million years, ago we had this forest and environment with mastodons and reindeer and hares running around in the landscape, together with a lot of plant species. the research was carried out in the northern most part of greenland in an area called the kap koebenhavn formation. 0ften scientists rely on animal fossils for a glimpse into the past but two million year old animal fossils are extremely rare there, so, instead, the team turned to something called environmental dna. this is genetic material shed from plants and animals, like skin cells or droppings, which build up in the surroundings.
in the landscape together with a lot of different plant species. the research was carried out in the northernmost part of greenland, in an area called the kap kobenhavn formation. often, scientists rely on animal fossils for a glimpse into the past, but 2 million year old animal fossils are extremely rare there, so instead, the team turned to something called environmental dna. this is genetic material shed from plants and animals, like skin cells or droppings, which build up in the surroundings. we are breaking the barrier of what we thought we could reach in terms of genetic studies. it was long thought that1 million years was the boundary or the barrier of dna survival, but now we are twice as old. the ancient soil offered up some unexpected results. 2 million years ago, for example, north greenland was much warmer than it is now. in fact, the average annual temperatures were about 11 to 19 degrees hotter. and the presence of mastodon dna
