How does a genus name show that the gray wolf and coyote are closely related?

The gray wolf (Canis lupus) and the coyote (Canis latrans) are classified within the same genus, Canis. In biological taxonomy, a genus is a rank used to group species that share a common evolutionary ancestor and exhibit closely related characteristics.1234

By sharing the same genus name, these animals are identified as being part of the same larger category, which reflects their close evolutionary relationship. This classification system, established through the binomial nomenclature introduced by Carolus Linnaeus, uses the first part of the Latin name to indicate this shared genus, while the second part distinguishes the specific species. Their close relationship is further evidenced by their ability to hybridize, producing offspring such as the eastern coyote or "coywolf".456
