The genus that includes modern humans and their closest extinct relatives is Homo.
Homo is a genus of hominins in the great-ape family Hominidae. Its only living species is Homo sapiens, while extinct members include Homo erectus, Homo habilis, Homo neanderthalensis, and Homo floresiensis. These species are grouped together because of shared anatomical and evolutionary characteristics, although the exact boundaries of the genus remain debated.
The genus probably emerged in Africa more than 2 million years ago. Homo habilis is traditionally considered one of its earliest members, while Homo erectus later became one of the most widespread and long-lived human species, expanding beyond Africa into parts of Eurasia.
Hominidae is the family containing humans and great apes, not the answer to the genus question. Pan is the chimpanzee-and-bonobo genus, and Australopithecus is an earlier hominin genus closely related to Homo. Neanderthals were not a separate genus; they are classified as Homo neanderthalensis.
