Answer:
long cold winters, with annual temperatures mostly below freezing.
The correct answer is coevolution.
The term is used to illustrate the conditions where two or more species communally influence each other’s evolution. For example, an evolutionary modification in the morphology of a plant may influence the morphology of a herbivore that consumes it, this, in turn, may influence the evolution of the plant that might influence the evolution of the herbivore and so on.
Coevolution most possibly takes place when distinct species have a close ecological association with each other. These ecological associations include parasite/host and predator/prey, mutualistic species, and competitive species.

Where are the answer choices
Answer:
C. This is an example of VNTRs.
Explanation:
VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
