Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.
Extinction of other species will negatively affect human society by affecting multiple things. One thing that may happen is that the ecosystem will fail, and it will eventually become a bare wasteland,n destroying possible recources for humans. As well, if humans have a direct use for them, such as cows for milk, or pics for bacon and ham, those direct recourses will deplete humans recourses, and there may be riots, or the population dwindling because of a lack of recourses. as well, some helpful animals such as plants go extinct, then no oxygen will be exchanged through photosynthesis, and it would cause a lot of pollution,
