Question

how can natural selection lead to a new species? match the series of events that can lead to the emergence of a new species. the pressure of natural selection is exerted on individuals who do not have the favorable trait. birds with the more favorable trait may become a new species. favorable traits become more common. a change occurs in the climate and rainfall decreases. the size of seeds available on the island changes.

Explanation:

First, a change in climate (like rainfall decrease) occurs, which can lead to a change in the size of available seeds on the island. This environmental change creates new selective pressures. Favorable traits related to dealing with the new - sized seeds then become more common in the population as individuals with these traits are more likely to survive and reproduce. Natural selection exerts pressure on individuals without the favorable trait, reducing their numbers. Over time, birds with the more favorable trait may become reproductively isolated and form a new species.

Answer:

1. A change occurs in the climate and rainfall decreases.
2. The size of seeds available on the island changes.
3. Favorable traits become more common.
4. The pressure of natural selection is exerted on individuals who do not have the favorable trait.
5. Birds with the more favorable trait may become a new species.
