The Impact of Ancient DNA Discovered in Siberia Essay -- Exploratory E

The Impact of Ancient DNA Discovered in Siberia For many decades, there has been an overwhelming curiosity about what life was wish well before humans ruled the earth - back when life on land, off land, and even the very land itself was very different than it is today. Pieces of this stay put have been discovered all over the world, ranging from perfectly preserved skeletons at the bottom of bodies of water to fragments discovered in vast deserts. Due to the conditions of the old-fashioned regains, there is only so much that can be decode about the past, which leads to the creations of various theories of what life was like in different areas and wherefore and when it changed. However, in at least one stretch of land, there is a lot that can be told thanks to one of the best finds in recent history some of the oldest DNA ever recovered.This amazing find was first reported in April of 2003, when it was told that animal and plant DNA was make up in the permafrost of northeastern Siberia (doubting Thomas 2003). The permafrost was located between the Lena and Kolyma rivers of former western Beringia and was drill out under scrupulous conditions using extreme care not to let any of the precious samples be have sex contaminated. In fact, strains of specialized bacterium were used to ward off any possible contamination (Willerslev 2003). The topic was led by Eske Willerslev of the University of Copenhagen in Denmark (Thomas 2003), whos international team looked towards oil production for sediment deposits in the layered ice when other areas containing possible ancient DNA samples provided only rare samples that were highly susceptible to extraction and mental test difficulties (Willerslev 2003). Fortunately, luck was with the international t... ...nd, oddly enough, the frozen digestive remains of prehistoric animals, important questions have been answered and fierce debates have been settled. This just goes to show that you neer know w here the next big ancient discovery is going to come from and gives hope for others to keep searching. Works CitedThomas, Abbie.
