Question

.A small moth pollinates native trees when they bloom in April. Some of the moths emerge in early March and discover a different blooming shrub to use as a resource. This is an example of what, over time, could be ________.

A) sympatric speciationB) allopatric speciationC) an invasive speciesD) an extinction for the original populationE) a change in age structure of the original population

Answer 1

This scenario is an example of sympatric speciation, where a new species forms within the same geographic location without a physical barrier. The moths that emerged in early March discovered a different blooming shrub and developed a breeding preference for that shrub, potentially leading to the formation of a new species over time.

Step-by-step explanation:

This scenario describes an example of sympatric speciation. Sympatric speciation occurs when a new species forms within the same geographic location without a physical barrier. In this case, the moths that emerged in early March discovered a different blooming shrub to use as a resource, which led to their interaction and breeding preference for that particular shrub.

Over time, the moths feeding on the different shrub may accumulate genetic differences from the original population, which could eventually lead to the formation of a new species.

Answer 2

The correct option is: A) sympatric speciation

Step-by-step explanation:

Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the existing common descent. The new species and the ancestral species all live in the same geographic area or location.

The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.
