Question

what categories does the remains or traces of once living things

A. Natural Selection

B. Adaptation

C. Genetic Variation

It's only one of these answers no others ones so choose the right one if these three answer choices

Answer 1

The correct answer is A. Natural Selection. The remains or traces of once living things can provide evidence for the processes of natural selection, which is the mechanism by which certain traits become more or less common in a population over time. Adaptation refers to the process by which organisms become better suited to their environment, and genetic variation refers to the diversity of genetic traits within a population. While these concepts are related to the remains or traces of once living things, they are not the specific categories that describe them.
