Did hunting by humans or climate change have more of a hand in the extinction of ancient megafauna?

    It is widely believed that climate change as a result of an asteroid impact resulted in the most recent catastrophic mega fauna extinction.  This extinction is known as the Cretaceous-Tertiary event having occurred around 65 million years ago.  Scientist believe a large asteroid impacted earth around the Yucatan Peninsula off the coast of Mexico.  The resulting ash, soot, and fires blanketed the Earth’s atmosphere causing widespread extinction of non-avian dinosaurs. Since then there have been small groups of extinctions such as those that occurred with the Wolly Mammoth, however none were even close to the scale of the Cretaceous-Tertiary event.
