Question

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.

Answer 1

Evolution is the change in characteristics of living things over time through natural selection, while coevolution is the mutual evolutionary influence between two species in close ecological relationships. Evolutionary changes are driven by environmental pressures, genetic variation, and are not necessarily tied to another species, unlike in coevolution.

Step-by-step explanation:

The main difference between evolution and coevolution is that evolution refers to the change in characteristics of living things over time, which occurs through natural selection and genetic variation, while coevolution involves the influence of closely associated species on each other's adaptation. In coevolution, as one species undergoes evolutionary changes, it affects the evolution of another species typically involved in a close ecological relationship. Evolution, on the other hand, can occur in response to a variety of environmental pressures and is not necessarily tied to changes in a specific other species.

Evolution does not have a predetermined goal of creating superior beings but is rather a response to changing environments, ensuring that species develop adaptations that maximize their reproductive success under current conditions. It's important to note that evolution can result in new species over time but does not always do so, as it can occur within the same species without leading to speciation.

Answer 2

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

Step-by-step 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.
