Question

Why do camesl have large flat feet?

Answer 1

Those features help them walk across desert sands. So that they are able to walk across sand without sinking in. We know that $Pressure=\frac{Force}{Area}$, The more the area, less the pressure will be.

They have large feet to spread their weight out over the sand, which helps to prevent them from sinking into it as pressure is deceased. Camels are adapted to walk long distances in deserts, hence, they have evolved to form large, broad, flat feet
