''Homo sapiens sapiens'' is believed to have appeared in Earth's fossil record between approximately 100,000 and 200,000 years ago ( | ''Homo sapiens sapiens'' is believed to have appeared in Earth's fossil record between approximately 100,000 and 200,000 years ago (an older branch of ''Homo sapiens'' known as ''[[Wikipedia:Homo sapiens idaltu|Homo sapiens idaltu]]'' was believed to have lived as far back as 160,000 BCE). While the exact origin of humanity is a hotly contested paleontological debate, it is likely that the first humans evolved from a genus of upright ape-like hominids called Australopithecus (likely ''[[Wikipedia:Australopithecus afarensis|Australopithecus afarensis]]''). | ||
The most successful species, ''Homo sapiens'' is not the only human to have evolved on Earth, but the ''Homo sapiens'' species, modern humanity, are believed to have either displaced or outlasted all other branches of the genus. Evidence exists that there was significant contact between anatomically-modern humans and other members of the genus, both cultural and genetic, coexisting with ''Homo erectus'', [[Neanderthal|''neanderthalensis'']] and [[Florian|''floresiensis'']], and, based on residual genetic evidence, interbreeding with other species (1-4% of the DNA in European and East Asian humans is neanderthal, while Melanesian people have 4% of a [[Wikipedia:Denisova hominin|close relative to the Neanderthals]] in their blood). Modern humans usually stand 6' tall, though this varies depending on nutrition, genetics and other factors. Members of the species, like some Covenant species, are four-limbed and bipedal, which enables them to walk upright on two legs and use their arms and hands (including opposable thumbs) to hold and manipulate objects such as tools. | The most successful species, ''Homo sapiens'' is not the only human to have evolved on Earth, but the ''Homo sapiens'' species, modern humanity, are believed to have either displaced or outlasted all other branches of the genus.
