Australian Megafauna Extinction Caused by Humans

From the BBC:

Humans hunted Australia’s giant vertebrates to extinction about 40,000 years ago, the latest research published in Science has concluded.

Human-lit fire – deliberately targeted and more frequent than lightning – had a devastating effect of plants that had previously been protected.

“Any climate change at those times was modest and highly unlikely to affect the outcome,” author Matt McGlone wrote in Science.

He said the latest study “supports a mounting number of studies that have argued that climate change was not primarily responsible for the Late Pleistocene extinctions in other parts of the continent.”
