| Research Abstract |
Fossilized DNA are sometimes preserved in anaerobic marine strata. This study is attempted to find fossilised DNA from deep-sea drill core beneath sea floor. Genome-level evolutionary biology for marine organisms are probably made with fossil DNA.
We tried to amplify DNA fragments from core samples collected by deep-sea drill vessel CHIKYU. We found DNA fragments with 100s to 1,000s bp from the core. Amounts of DNA are more than 0.6ng/ul/mg dry weighted sediments. Two to four marine eukaryotic groups were identified in the DNA fragments. We believe that we have gotten a proof that fossilized DNA are certainly preserved in anaerobic environmental conditions which are created in the deep-sea sediments.
