Based on the analysis of fossil teeth conducted by researcher Alejandro Romero, from the University of Alicante's Departament of Biotechnology, a study shows that short-faced bears (Arctodus simus), the largest carnivores in the Ice Age, became omnivores to survive. The study, led by the University of Málaga (UMA) researcher Borja Figueirido, was recently published in the journal Scientific Reports.

The UA researcher also highlights that “this is an interesting study, as caries were found for the first time in the dental remains of Arctodus simus, which proves that they could adapt to plants present in their diet as a result of climate change or competition with other predators”.
