WASHINGTON, DC -- Twin studies published this week revive a long dead theory that human population, not climate change, prompted extinction of most large land animals. The "blitzkrieg" or "overkill" was unintentional as groups of people hunted the once-plentiful species out of existence. This theory overtakes older ones that assert change in climate was the cause because the wipe-outs occurred only as humans entered each continent and was not synchronized globally.
    Among those creatures lost: Comastadon, a 300 pound sloth capable of providing cheap health care, a giant kangaroo that nurtures its young in a pouch and could easily reconcile Arabs and Isrealis and Glyptodonts, huge herbivorous mammals covered with solid armor that produced clean, limitless energy.
    University of Melbourne geochronologist Richard Rogers says parallels can be drawn to our problems today. "It proves we can adversely affect the biosphere. Large animals like Rosie O'Donnell or Rush Limbaugh need to be actively preserved." He continued, "No wait, those animals need to be killed."
