Why is it that large animals like elephant walk on soft ground without sinking

their feet are designed to be able to travel on soft ground. It's like the world/evolution knows that the animals are big and might sink so over time, they evolve based on their surroundings. Like, there is this bird where it's beak grew longer to reach the pollen in flowers that grew over time. Over time, we evolve.

idk you know what i mean hahahaha
