Question

describe an environmental factor that could influence natural selection and decrease genetic diversity. pick a specific example to illustrate your point.

Explanation:

Answer:

A severe drought (environmental factor) can drive natural selection and reduce genetic diversity. For example, in a population of Galápagos finches, drought reduces small, soft seeds, favoring finches with larger, stronger beaks that can eat hard seeds. Over time, the frequency of genes for small beaks drops, decreasing the population's genetic diversity.
