In a study published in Science, paleontologists have found strong evidence that human arrival in Australia significantly contributed to the extinction of numerous kangaroo species.
Larisa DeSantis cautions that focusing on only one point in time may overlook critical roles climate changes have played in past extinction events.
Kangaroos adapted their diets and locomotion to a progressively arid climate over millions of years, which led to their diversification into various species.
Understanding whether human impact or climate change was a more significant factor in the extinction of large mammals could provide insight into today's biodiversity crisis.
