Gill speaks to Scientific American about fossils in La Brea tar pits

Scientific American spoke to Jacquelyn Gill, associate professor of paleoecology and plant ecology with the University of Maine School of Biology and Ecology and Climate Change Institute, about new research into the famed La Brea Tar Pits published on Aug. 17 in Science. “We know that in modern systems, extinction is very rarely unicausal. You often need to have some force that’s stressing this population. Then there’s often an element of bad luck or some other stressor that comes in. We see that over and over again,” Gill said.
