What is the difference between evolution and coevolution? a) Evolution of one species only occurs in response to natural selection based on the changing environment that species lives in at a particular time. b) Coevolution is the only way speciation can occur. c) These concepts are not different; they only differ on time scale. d) Coevolution results when two or more species influence adaptation in each other.

d) Coevolution results when two or more species influence adaptation in each other.

Explanation:

The coevolution is a process of evolution in which two or more species affects each other evolution by the process of natural selection. The evolution of one species is dependent upon other species in coevolution process.  The coevolution is affected by the mutualism, predator prey relationships and host parasite relationships.

In the course of evolution of one species adapt to the natural changes occurring in the environment. The changes occurring is one species remain unaffected of the other species.

the answer is a or when it says crossing over
