Question

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

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

Answer 1

The most accurate response to the given scenario is:

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

This response reflects the current trend in classification systems where genetic information and evolutionary relationships are emphasized over traditional morphological characteristics. If genetic testing indicates that the organism is more closely related to bacteria than to plants, it would be appropriate and scientifically justified to reclassify it accordingly.
