apes and humans are classified as hominids
The earliest classification systems grouped organisms based on observable physical features, such as morphology and anatomy. This system organized living things into categories based on similarities in structure and behavior.
Simians are a classification of primates, which includes monkeys, apes, and humans.
If you are asking for biological classification then: animalia mammalia cordata primates hominidae homo homo sapiens

The Dewey Decimal classification 599.665 is for primates, specifically for the group of primates known as Old World monkeys.
Anatomical structures provide physical characteristics that can be compared across different organisms to identify similarities and differences. These similarities and differences can help in grouping organisms into taxonomic categories based on shared traits. By analyzing anatomical structures, scientists can infer evolutionary relationships and determine how various species are related to one another.

Because they do not have the attributes of a primate and do not meet the classification systems criteria for primates.
Hilobatidae/hylobatidae is the 'family' name of the type of primates called Gibbons in the scientific classification system.
There are many different species of monkeys (simian primates), each with its unique 7-level classification. For example, for the olive baboon: Kingodm: Animalia (animals) Phylum: Chordata (hollow dorsal notochord) Class: Mammalia (mammals) Order: Primates Family: Cercopithecidae (old world monkeys) Genus: Papio (baboons) Species: Papio Anubis (olive baboons)
Humans belong to the order Primates and the genus Homo. Here is the full classification of Homo sapiens sapiens: Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae Genus: Homo Species: H. sapiens Subspecies: H. s. sapiens
KINGDOM: animilia PHYLUM: chordata CLASS: mamilia ORDER: primates GENUS: homo SPECIES: sapiens
