Biological investigate useful DNA test. Lab test.blood test etc
-because distinct populations of living things exist due to barriers to reproductive change.
-because fossils may be classified into distinct taxa due to the persistence of gaps.
The two reasons why the gaps among existing organisms, as well as the fossil records have remained after hundreds of years of research are because of distinct populations of living things exist due to barriers to reproductive change and because fossils may be classified into distinct taxa due to the persistence of gaps.
The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
