回答: Human hunting is one of the prevailing hypothesis these days. 由 Latino2 于 2005-5-12, 12:39:02:
because of climate change, human saw a need and/or opportunity to move. Large animals then suffered the ruthless killing by migrating human beings, in addition to the disastrous climate change.
One hypothesis is that if animals died out due to climate change, it should occur at a slower pace, as the last climate change was not particularly dramatic.
