As classification systems evolved, scientists shifted from using dichotomous keys and only physical characteristics. They now incorporate genetic information and evolutionary relationships when classifying organisms.

A hypothetical organism was previously grouped based on its plant-like appearance, but genetic testing has revealed that it is more closely related to bacteria.

How does this shift affect this organism’s classification?

The organism would be reclassified as bacteria since classification is now more dependent on genetic testing.

The organism’s classification would not change since dichotomous keys rely on physical traits first
The organism’s classification would not change since dichotomous keys rely on physical traits first

The organism would remain classified with plants since it has already been classified as a plant
The organism would remain classified with plants since it has already been classified as a plant

The organism’s classification may not change since the dichotomous keys do not change.

The correct response would be:

The organism would be reclassified as bacteria since classification is now more dependent on genetic testing.

This answer reflects the modern approach to classification, which prioritizes genetic information and evolutionary relationships over solely physical characteristics.
