Researchers suggest human arrival in Australia, not climate change, mainly caused kangaroo extinctions.
A new study in Science suggests that the arrival of humans in Australia may have played a bigger role in the extinction of kangaroo species during the Pleistocene era than climate change.
Researchers analyzed ancient and modern kangaroo teeth and found that extinct species had mixed diets, consuming both grasses and shrubs.
While some experts argue climate change also contributed, the study highlights the impact of human activities on past and current biodiversity.
