How did you weigh the different pieces of evidence to reach a conclusion to questions (2) and (3)? What evidence was most important, what was least important, etc.?

Following are the solution to the given points.

Explanation:

Even though the two flights can differentiate physically, their genetic variation supports the idea over an amount of time of their development as distinct species. Because it is not as long as this is necessary for such a species to evolve fully, it is referred to it as different races of the same species and has also been designated as 'Rhagoletis Pomella's technical term.

Its main proof is the biological heterogeneity between them, their unique niche, and their reduced reproductive fidelity. Its visual resemblance was the least important. Throughout the future reproductive faithfulness will be nil. In the last 100 years, those fly just developed, owing to the time needed for full development, and therefore this species is evolving.

what are the options?

answer; ///the above statement is (false);
