Detailed explanation-1: -Two species within the same genus likely share a recent common ancestor in their evolutionary history. These two species would be more closely related to each other than two species classified into different families. Table 1.10. The number species decreases in each group moving down the levels of classification.
Detailed explanation-2: -Answer and Explanation: When we look at the taxonomy of a species we’re essentially given a lineage that tells us to what kingdom, phylum, class, order, family, genus, and species the organism belongs to. When we compare two species the more taxa they have in common the more closely related the species are.
Detailed explanation-3: -Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
Detailed explanation-4: -In general, the more levels species share, the more closely they are related. Coyotes, gray wolves (Canis lupus), domestic dogs (Canis familiaris), and jackals (four Canis species) all belong to the same top seven taxa (domain, kingdom, phylum, class, order, family, and genus).
