NYT Magazine interviews Jacquelyn Gill on Younger Dryas impact

The New York Times Magazine interviewed Jacquelyn Gill, an associate professor of terrestrial paleoecology at the University of Maine, on controversy surrounding the Younger Dryas impact theory, which claims that a comet struck the Earth 12,900 years ago and caused a sudden cooling widespread death among large, ancient mammals. Gill said she was doubtful of it because there is evidence suggesting that many large mammals were already in decline or even extinct thousands of years before the onset of the Younger Dryas, and many others lingered long after.
