Answer:
The correct answer are "class; yes; no; the two insect species that share the most recent shared common ancestor are the ones in the same family; insect species X and insect species Y are more likely to have the most recent common ancestor".
Step-by-step explanation:
Species are categorized in different taxonomic ranks according to physical and genetic features that establish the degree of similarity between species. For instance, two species that are in the same order have a more recent common ancestor than two species that have the same class. Also, two species that have the same genus share the other taxonomic ranks that are in an upper section. In this case, two insects in the same family are in the same order (the next taxonomic rank in an upper section) however, two insects that are in the same order not necessary are in the same family (the next taxonomic rank in an downer section).
