What does genus mean and give examples?

Answer 1

In biological classification, a genus is a rank that groups together species that are closely related and share a common ancestor. It is one level above species and one below family in the taxonomic hierarchy. For example, the genus Canis includes species like the domestic dog (Canis lupus familiaris) and the gray wolf (Canis lupus). Another example is the genus Homo, which includes modern humans (Homo sapiens) and our extinct relatives like Homo neanderthalensis.
