But every time her lab publishes research relating to the reasons why the mammoth went extinct, she told Salon, someone calls her up (sometimes it's her mom) and asks, "Does this mean we can clone a mammoth?"

Beth Shapiro is an evolutionary biologist specializing in ancient DNA, a complex field (which she pioneered) that uses genetic information from long-dead species to learn how past populations responded to previous periods of rapid climate change - lessons she hopes we might use to preserve biodiversity today.
