Mammals that chose ants and termites as food almost never go back

The news article discusses how mammals that have chosen ants and termites as their primary food source are unlikely to revert to other dietary preferences. Ant-eating, known as myrmecophagous behavior, is prevalent across various mammalian lineages. The article suggests that once a mammal species has evolved to specialize in this type of diet, it is highly unlikely for them to abandon it and return to a more generalized feeding strategy. This evolutionary trend highlights the significant adaptations and specializations required for mammals to successfully exploit the resources provided by ants and termites as a primary food source. The article emphasizes the strong selective pressures and ecological advantages that have led certain mammalian species to become highly dependent on these insects as a reliable and consistent food supply, making it challenging for them to revert to alternative dietary choices.
