An organism was hunted almost to extinction, but the population bounced back. which evolutionary change did this species most likely experience?

Population Bottleneck

Explanation:

The bottleneck effect occurs when changes occur in the environment, so as to dramatically reduce the size of a population. The name “bottleneck effect” stems from the fact that only part of the population resists a certain pressure from the environment. It would be like a bottle full of marbles, with only a few going through the neck and some not. An example of this occurs when a small population of an almost extinct species of animals has survived and reproduced.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
