Humans.We are the only hominid species that still exist. Our taxon is Homo-Sapien Sapien. Most people just say Homo-Sapien, even though the actual Homo-Sapien species is extinct.
The only existing hominids are humans. To be a hominid a species must be closer to humans than chimpanzees.
The scientific name for the hominid Ardi is Ardipithecus ramidus. It is an extinct hominid species that lived around 4.4 million years ago.
