Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus , Homo , is designed to include both anatomically modern humans and extinct varieties of archaic humans .
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Homo (from Latin homÅ 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
A life form (also spelled life-form or lifeform) is an entity that is living, [1] [2] such as plants , animals , and fungi . It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, [ 3 ] are extinct .
Many metazoan (higher animals) orders also have such suffix, e.g. Hyolithida and Nectaspida (Naraoiida). Forming a name based on a generic name may be not straightforward. For example, the homo has the genitive hominis, thus the genus Homo (human) is in the Hominidae, not "Homidae".
Even compared with other social animals, humans have an unusually high degree of flexibility in their facial expressions. [291] Humans are the only animals known to cry emotional tears. [292] Humans are one of the few animals able to self-recognize in mirror tests [293] and there is also debate over to what extent humans are the only animals ...
Human remains found in a desert in 1992 have now been identified as a missing 15-year-old girl, Arizona officials said. The “decomposed remains were found in a remote desert area” of Apache ...
Most DNA studies find that humans and Pan are 99% identical, [19] [20] but one study found only 94% commonality, with some of the difference occurring in non-coding DNA. [21] It is most likely that the australopithecines, dating from 4.4 to 3 Mya, evolved into the earliest members of genus Homo .
