    Is Climate Change Driving Another Mass Extinction?

    Darwin Day at Duquesne Explores Evolution and the Future of the Planet

    Every fifth-grader knows dinosaurs roamed the Earth once but don't live here anymore. If we adults think we're smarter than fifth-graders, are we aware of extinctions occurring before our very eyes?

    Extinction, evolution and rapid climate change will be the topics of Duquesne University's annual free Darwin Day discussion on Friday, Feb. 17 at 7 p.m.

    Renowned paleontologist Dr. Peter D. Ward, professor at the University of Washington in Seattle, will address the causes of major mass extinctions-periods of time when more than half of all species on Earth disappeared-and the evolutionary effects they had in shaping our world.

    Ward, a favorite on PBS, NOVA, TED and Animal Planet, will discusses Mass Extinctions: The Third Tier of Evolution, and will weigh whether we are experiencing a new mass extinction driven by human-induced climate change.

    "There have been five major mass extinctions, all attached to rapid climate change, requiring rapid changes in organisms," said Dr. David Lampe, associate professor of biology and Darwin Day organizer. "Organisms that didn't adapt went extinct."

    Already, about one-third of all amphibian species are endangered and nearly 170 species are believed to have gone extinct over the last two decades, even in protected habitats. Many plants are also in danger.

    "Everything," Lampe said, "is based on a predictable climate."

    To learn more about extinctions, past and present, attend the free, public event in the University's Power Center Ballroom, Forbes Avenue and Chatham Square, Uptown.

    Duquesne University

    Founded in 1878, Duquesne is consistently ranked among the nation's top Catholic research universities for its award-winning faculty and tradition of academic excellence. The University is nationally ranked by U.S. News and World Report and the Princeton Review for its rich academic programs in 10 schools of study for 10,000-plus graduate and undergraduate students, and by the Washington Monthly for service and contributing to students' social mobility. Duquesne is a member of the U.S. President's Higher Education Community Service Honor Roll with Distinction for its contributions to Pittsburgh and communities around the globe. The U.S. Environmental Protection Agency and the Princeton Review's Guide to Green Colleges acknowledge Duquesne's commitment to sustainability.
