Question

in order for natural selection to take place, we must have a.one individual b.a cloned species c.the same traits d.variety in a population

Answer 1

Natural selection can only occur because of a variety in a population. Natural selection refers to environmental factors that affect a population and causes some of the population to have more surviving offspring than others. An example is a giraffe with a longer neck will be more likely to survive and reproduce (as it can gather more food from taller trees)
