Arctic Snow Fox Evolution

Introduction: Due to moving the arctic snow fox to the tropical rainforest, the snow fox will experience tremendous amount of evolutionary impact. So due to speciation, the formation of a new species due to evolution, it will be called a Forest Fox. The Arctic Snow Foxes environment is very frigid. They feed on the weakest of animals, and even feed of of the leftovers of other animals like polar bears. One of its predators is a polar bear, but because of its white fur, it is very hard to spot. The common arctic fox descended from the Vulpes Qiuzhudingi, making it the common descendant.

Structure: Fur Color
Function: Camouflage
Evolutionary Change: Bottleneck Effect
Explanation: The Arctic Snow Fox has fur that is very white because in its …show more content…

But since we are moving it to a environment where it will be walking across steep tree branches, then its claws will need to be able to dig in to the tree trunk. So instead of its claws sticking out, making them a homologous structure to a cat. This is convergent evolution because a fox and a cat are not very closely related, but they have traits that are related.

Structure: Fur Design
Function: To attract Mates
Evolutionary Change: Sexual Selection
Explanation: The arctic snow fox doesn’t have any designs on it fur, but due to sexual selection becoming a effect in the population than, fur design will become relevant because if the female is attracted to stripes and they had stripes then it will keep evolving to fit the females needs in fur design.

Structure: Leg
Function: To be able to move
Evolutionary Change: Bottleneck Effect
Explantation: Due to the bottleneck effect the forest fox will lose its genetic variation between leg size because the forest foxes with the shorter legs have a lower chance of survival because the ones with the longer legs will end up being more athletic. Also due to co-evolution with its predators like a tiger, the fox will grow legs to be able to outrun the tiger, but the tiger will also evolve to have longer legs to be able to catch the fox. This is macroevolution because all land mammals will need to have longer legs because the faster they …show more content…

So they will be there as a vestigial structure because the fur on the bottom of the feet is not hurting them. For the snow fox they needed it to travel on snow more efficiently

Structure: Liver
Function: To turn toxins unharmful
Evolutionary Change: Analogous Structure and Human Involvement
Explanation: The liver in the forest fox will grow to filter out the toxins of the water because of the human involvement. Humans are putting trash and oils into the water, so having a larger liver will help filter out the water when they have to drink it. This can also be a analogous structure because it is different sizes for every animal but it serves the same purpose.

Structure: Fright and flight effect
Evolutionary Change: Behavior
Function: To run when it sees or hears something
Explanation: This trait will be beneficial to the forest fox because if it hears a predator it will run due to the fright and flight effect. This behavior came when forest fox would hear something but wouldn’t run. So the predator would catch the fox because its instincts weren’t fast enough. But due to natural selection the forest fox began to start running if they felt like they were in danger there would be more forest fox who would
