Getting Better at Studying Ancient DNA (1 of 7)

Caption

Scientists working in the Klondike gold fields near Dawson City, Yukon Territory, uncover thousands of bones, tusks, and teeth representing the preserved remains of the ice age megafauna. Here, Jana Morehouse crouches behind a frozen mammoth tusk that was exposed as part of placer mining activities. Remains such as these are used in paleogenomic analyses to understand processes including genome evolution and how populations respond to climate change over the short and medium term. This image relates to a paper that appeared in the 24 Jan., 2014, issue of Science, published by AAAS. The paper, by B. Shapiro at the University of California, Santa Cruz in Santa Cruz, CA, and colleagues was titled, "A Paleogenomic Perspective on Evolution and Gene Function: New Insights from Ancient DNA."
