Crazy Capybaras

I think the tropical rainforest will become a savanna with little or no water. Capybaras will live in groups to protect each other from their predators. They will live in hotter climates so the capybaras will turn nocturnal when it’s colder to avoid the heat of the day. But in the winter, they might change to be diurnal. They will eat more dried grass, get more stomachs, so their stomachs will start producing more acid to break down all the dried grass they eat. Capybaras can hold their breath for 5 minutes under water, so they’ll adjust their lungs and won’t need to hold their breath for as long. Which will give them more space for their stomachs. They’ll get an aerodynamic body instead of a barrel-shaped body, so it’s easier to run away from their predators. They will also concentrate their urine for more water.
