Explanation:
Microsatellite DNA is commonly used in the case of studying evolutionary relationships among various species of fauna. Microsatellites, also known as simple sequence repeats (SSRs), are short repeated DNA sequences found throughout an organism's genome. These repetitive sequences can vary in length between individuals and species, and their analysis allows scientists to compare the genetic variation and relatedness among different populations or species. By studying microsatellite DNA, researchers can gain insights into genetic diversity, population structure, and evolutionary relationships in the animal kingdom.
