Prehistoric specimens being prepared for DNA test. Researcher handling specimens that will be tested for their DNA (deoxyribonucleic acid) content. DNA is the genetic material that controls the growth and development of living organisms. These specimens were excavated at the Cova des Pas prehistoric site, a cave on the Mediterranean island of Menorca, Spain. It was used as a burial site by the pre-Talaiotic and Talaiotic cultures. Around 100 burials have been found there, including 70 nearly complete skeletons, with preservation of organic matter and soft tissues. The burials date from between 1200 and 800 BC. The site was discovered in 2005, with researchers carrying out excavations and laboratory analysis of their findings. Photographed in 2005, in a laboratory at the Autonomous University of Barcelona, Spain.
