evolution project


past
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.


present
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.


future
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.

The six terms




Adaptation it is how animals get used to a place for survival. an example of adaptation is how animals have to adapt to the environment in the island to survive, in the video the animals have special caracteristics to survive in that especific environment.


variation is when there is different types of species, an examplo of variation is the variation of beacks in the finches, they use the variation of beacks to do different jobs. there are 134 different types of finches.

speciation is when a new species is formed, one example is when the warm currents hit galapagos and new flowers are formed,

Selection is when traits get more popular depending on the environment for example some finches have specific beacks to do their nests on cactus that is a popular trait in the part of the island with more cacti.

Overpopulation is when the supplies don't meet the number of demand of the populatio, this happend when people were starting to go to Galapagos and they didn't find enough food to meet the demand of the people 

Insulation is when a object is totally separated from  another, in this case Galapagos is totally isolated from the rest of the civilization
