The foxes come from the canidae family which is the same family of the coyote fox and the racoon all of them have similar traits. Skull fossils found from different canidae although they are all different animals they all have the same traits of the fox, they all have the long snout and large eye holes wich are in front.
The foxes have many features each varying their environment. they have long flexible necks that allow them to move their head freely for better sight to catch their prey, they have large eyes in front so that they can see their prey while running they have the nostrils in front to smell prey and predators, also they have sharp teeth and strong jaw muscles to eat their prey without problem, their strong hips give them power to run faster also their compact short toes and feet, using their long leg bones to gain more speed.
The fox in the future will have the traits he needs to catch prey in the wild because in a million years from now humans will not exist, most likely nature will recover itself like it always does,that means that for foxes they will adapt to catch prey all over the world they will most likely have the basic features like short legs, long snout, large eyes in the front part of the head because these are the features of a runner (like the fox). Foxes have adapted through the years to some environments when humans are gone there will be more varieties of biomes so they will have adaptations for those biomes like different fur colors, different sized ears for surtan environments, and very certainly different types of tails to fit their biome.
