Update: Humans linked to animal extinction WASHINGTON (AP)
For more than a century, scientists have debated what killed off the big animals in Australia and the Americas. Now, two studies blame ancient human hunters equipped with fire, spears and an appetite for meat.
The studies conclude that after early humans migrated into Australia and the Americas, the heavyweight animals of these new continents were driven to extinction within a few thousand years. The research contributes powerful new evidence to a century-old debate among scientists intrigued by the question:
What killed off the big animals in newly settled continents of the world?
Some have long blamed humans, but other experts say it could have been climate
change, disease or a gradual change in habitat. The two new studies pin the
blame firmly on humans.
