Speakers Peter Ward: Paleontologist http://www.ted.com/index.php/speakers/peter_ward.html The Medea Hypothesis: Is Life on Earth Ultimately Self-Destructive? by Peter Ward http://press.princeton.edu/titles/8855.html http://press.princeton.edu/titles/8855.html#TOC “Using the latest discoveries from the geological record, he argues that life might be its own worst enemy.” “According to the Medea hypothesis, it does. Ward demonstrates that all but one of the mass extinctions that have struck Earth were caused by life itself. He looks at our planet's history in a new way, revealing an Earth that is witnessing an alarming decline of diversity and biomass--a decline brought on by life's own "biocidal" tendencies.” Yours, Paul H. ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
