a model of natural selection is shown here with a small beetle population. some green beetles in the original population are shown as dying by predation. the resulting population several generations later is shown on the right. which of these explanations should be selected to account for the changes in the population of beetles shown here? a individual green beetles evolved to be less adapted, resulting in a change in allele frequencies in future generations. b individual brown beetles evolved in the presence of the predator to be better adapted, making it more common in future generations. c green beetles that survived the presence of the predator migrated to different populations, decreasing their frequency in the subsequent populations. d beetles with brown coloration survived with greater frequency in the original population, resulting in a greater frequency of brown beetles in subsequent populations.

Answer

Brief Explanations:

Natural selection favors traits that increase survival and reproduction. Brown - colored beetles likely had a survival advantage over green beetles in the presence of the predator in the original population. This led to a higher frequency of brown - colored beetles in subsequent generations as they were more likely to survive and pass on their genes. Option A is incorrect as evolution acts on populations, not individuals. Option B is wrong because individual beetles do not evolve in response to predators; populations evolve over time. Option C is not supported by the information given as there is no indication of migration.

Answer:

D. Beetles with brown coloration survived with greater frequency in the original population, resulting in a greater frequency of brown beetles in subsequent populations.
