This table shows the evolutionary history of a population of beetles . review the trends to determine which evolutionary mechanisms is in play

In the particular order from top to bottom , the answers are;

Genetic drift

Gene flow

Natural Selection

Gene flow occurs during migration where alleles from one population are introduced to another population hence increasing the population diversity.

Genetic drift occurs when the allelic frequency of a population changes due factors such as calamities and emigration or natural selection.

Natural selection is the force of ‘survival for the fittest’ that is applied differentially on the population by nature.  

answer; ///i believe the correct answer is (aids) acquired immune deficiency syndrome;
