What is a fossil?
Fossils are fossilised (petrified) remains of animals/plants. A fossil though, is only a fossil, when it is from a different geological era.
How does that relate to evolution?
Evolution and fossils are very related. When we scan the DNA of different fossils, we find that the DNA can be similar to living species we have today, which helps us trace back their origins.
Tracing back a species origins is not something we do just to see how that species changed along time. When we manage to make an evolutionary chart of a species, we know how they changed, what they changed, and maybe not more, but very importantly, when the previous species were extinguished. If we know when they were extinguished, we can find out what caused that extinction:
- A lack of adaptation.
- Lack of resources.
- Temperature changes.
- Increase of predators.
- Deadly migrations.
- Other natural disasters.
So, in other words, by studying one species, we can study our own planet.

Answer:
No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t
he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni
che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver.
If the gray wolf became extinct, the coyote population increases in that location due to no predator.
