A professor at the University of Alaska Fairbanks is adding new fuel to a long-established theory on what caused the dinosaurs to go extinct. Michael Whalen is a contributing author to a study published in the journal “Science” earlier this month that argues a massive asteroid slamming into the Yucatan Peninsula eventually led to the mass extinction event. The article is in part a response to another theory- that the extinction was caused by long term volcanic activity in India.
