Gibraltar monkeys eat soil to digest

Gibraltar monkeys eat soil to digest

Scientists from Cambridge University have observed a unique dietary habit among Gibraltar's famous monkey population: geophagy, or the intentional consumption of dirt.

The macaques appear to use the minerals in the soil to neutralize toxins and settle their stomachs after consuming processed foods like Haribo and crisps.

This behavior is believed to be learned socially within the troops, as younger monkeys mimic the actions of their elders.

The findings highlight the unexpected ways in which wildlife is adapting to the presence of high-calorie, low-nutrient human food in their environment.
