Arguments Against Both Climate Change and Overkill
Detractors have asserted that neither the overkill nor climate change hypotheses can explain several observations. Among these are the observation that browsers, mixed feeders and non-ruminant grazer species suffered most, while ruminant grazers generally survive However a broader variation of the overkill hypothesis may predict this, because changes in vegetation wrought by anthropogenic fire preferentially selects against browse species. Because of perceived shortcomings of the overkill or climate change hypotheses alone, some scientists support a combination of climate change and overkill.
