Eight samples of ancient spruce DNA were found frozen on the North Slope. The samples are about 80,000-130,000 years old. 50,000 years ago, the North Slope was glaciated. We have successfully extracted DNA from 1 sample. We will conduct future extractions on the remaining samples and identify their species.
