Capybaras, now and later

We can see that the capybara today is very fury, and big to survive in the rainforest. It is big to hold more food and defend itself better. It also has a lot of fur to keep itself warm and dry in a wet environment. In about 1000 years, I predicted that the rainforests will become deserts so I imagine the capybara adapts in such a way that a desert fox does. I think that it will lose a lot of its fur, weight, and anything else adding extra heat. I imagine that it will have bigger ears to hear prey better and have a smaller head to eat better. I lastly imagine the future capybara to have longer legs for better mobility.
