Viking burials yield uncontaminated Viking DNA for important analysis
Vikings are well known in mythology and stories for wearing their famous helmets and being buried with their treasures. Archeaology has discovered some of these helmets, which has provided much detail about the lives of Vikings. Now scientists have now used the human teeth and tissue from the Viking skeletons that have lain undisturbed, buried with their artefacts for over 1000 years, to extract pure Viking DNA to tell us more...
The researchers overcame problems that have plagued previous studies - that of contamination. All living things have DNA and examining archeaological finds always leads to investigators DNA being left on the finds. Danish researchers planned this excavation carefully. They took samples from teeth and bones for DNA testing moments after the ancient skeletons were first unearthed, before any DNA could contaminated the area.
