Homo is the genus that comprises the species Homo sapiens, which includes modern humans, as well as several extinct species classified as ancestral to or closely related to modern humans—as for examples Homo habilis and Homo neanderthalensis. The genus is about 2.8 million years old; it first appeared as its earliest species Homo habilis, which emerged from the genus Australopithecus, which itself had previously split from the lineage of Pan, the chimpanzees.The line to the earliest members of Homo made final separation from the lineage of Pan by late Miocene or early Pliocene times—with date estimates by several specialists ranging from 13 million years ago to more recently than six million years ago.

  • "Patterson et al. suggest that the apparently short divergence time between humans and chimpanzees on the X chromosome is explained by a massive interspecific hybridization event in the ancestry of these two species. However, Patterson et al. do not statistically test their own null model of simple speciation before concluding that speciation was complex, and—even if the null model could be rejected—they do not consider other explanations of a short divergence time on the X chromosome. These include natural selection on the X chromosome in the common ancestor of humans and chimpanzees, changes in the ratio of male-to-female mutation rates over time, and less extreme versions of divergence with gene flow. I therefore believe that their claim of hybridization is unwarranted." see current estimates regarding complex speciation.

Taxonomically, Homo is the only genus assigned to the subtribe Hominina which, with the subtribes Australopithecina and Panina, comprise the tribe Hominini (see evolutionary tree below). All species of the genus Homo plus those species of the australopithecines that arose after the split from Pan are called hominins.

Homo erectus appeared about two million years ago in East Africa (where it is dubbed Homo ergaster) and, in several early migrations, it spread throughout Africa and Eurasia. It was likely the first hominin to live in a hunter-gatherer society and to control fire. An adaptive and successful species, Homo erectus persisted for almost 2 million years before suddenly becoming extinct about 70,000 years ago (0.07 Ma)—perhaps a casualty of the Toba supereruption catastrophe.

Homo sapiens sapiens, or anatomically modern humans, emerged about 200,000 years ago (0.2 Ma) in East Africa (see Omo remains). There is division among scholars as to when H. s. sapiens became behaviorally modern; the debate is: modern behavior developed 1) simultaneously with anatomical development, or 2) separately, and was complete by 50,000 years ago (see Modern human behavior). Homo sapiens sapiens is the only surviving species and subspecies of the genus Homo; all others have become extinct.

Modern humans migrated from Africa as recently as 60,000 years ago, and during Upper Paleolithic times they spread throughout Africa, Eurasia, Oceania, and the Americas; and they encountered archaic humans en route of their migrations. Some archaic humans outside Africa survived alongside modern humans until about 40,000 years ago ( see H. neanderthalensis), and possibly until as late as the times of the Epipaleolithic culture (about 12,000 years ago). DNA analysis provides some evidence of interbreeding between archaic and modern humans, although some researchers have doubted these findings.

Homo (disambiguation)

Homo is the taxonomical genus that includes modern humans (Homo sapiens sapiens).

Homo may also refer to:

  • ὅμο-, Greek prefix meaning "the same", opposite of "hetero-" (Greek ἕτερο- )
  • Homo, an abbreviation for homogenized milk
  • Homo-, in chemistry, a prefix indicating a homolog, an organic analog of next higher straight chain/ring size at some part of molecule
  • HOMO, in chemistry, highest occupied molecular orbital
  • Homo, Latin for "man", " human being"
  • HomO, the Swedish Ombudsman against Discrimination on Grounds of Sexual Orientation
  • Homo (slang), an abbreviation for "homosexual"
  • Homo, wolfhound in Victor Hugo's novel The Man Who Laughs

Usage examples of "homo".

Galli castra munire instituerunt et sic sunt animo confirmati, homines insueti laboris, ut omnia quae imperarentur sibi patienda existimarent.

In the early 1950s, Sir Solly Zuckerman published extensive biometric studies showing Australopithecus was not as humanlike as imagined by those who favored putting this creature in the lineage of Homo sapiens.

Ecce Homo chapel not long since, they still left one centesimo and a waistcoat button on the floor.

But according to the faunal evidence reported by Qiu, all that can really be said is that the age of the Homo sapiens fossils could be anywhere from Middle Pleistocene to Late Pleistocene.

If we place Tongzi Homo sapiens in the older part of its true faunal date range, in the middle Middle Pleistocene, he would be contemporary with Zhoukoudian Homo erectus.

But our own analysis of the faunal evidence, site stratigraphy, and paleomagnetic dating shows the date range for the Lantian Homo erectus skull overlaps that of Zhoukoudian Homo erectus.

That scientists could confront the faunal evidence at Changyang without even considering the possibility that Homo sapiens coexisted in China with Homo erectus is amazing.

Over the past century, scientists have accumulated evidence suggesting that humanlike creatures resembling Gigantopithecus, Australopithecus, Homo erectus, and the Neanderthals are living in various wilderness areas of the world.

According to Weidenreich, Homo sapiens evolved from Gigantopithecus by way of Meganthropus and Pithecanthropus.

Sexual acts: hetero, homo, bestial, nymphomania, satyriasis, and all the erotic postures of desire, passion, lust, love, and pleasure.

Cassivellaunus, ut supra demonstravimus, omni deposita spe contentionis dimissis amplioribus copiis milibus circiter quattuor essedariorum relictis itinera nostra servabat paulumque ex via excedebat locisque impeditis ac silvestribus sese occultabat, atque eis regionibus quibus nos iter facturos cognoverat pecora atque homines ex agris in silvas compellebat et, cum equitatus noster liberius praedandi vastandique causa se in agros eiecerat, omnibus viis semitisque essedarios ex silvis emittebat et magno cum periculo nostrorum equitum cum eis confligebat atque hoc metu latius vagari prohibebat.

In 2226 they had sponsored preliminary research on the creation of a new Homo subspecies capable of surviving on certain heavily irradiated, notoriously inhospitable R-class planets deep within the galactic hub.

For example, most of the Homo erectus discoveries reported by von Koenigswald in Java were made by native diggers, who, unlike Parodi, did not leave the fossils in situ but sent them in crates to von Koenigswald, who often stayed in places far from the sites.

Even if we grant that every other bone connected with Piltdown is a forgery, if the skull was found in situ, we are confronted with what could be one more case of Homo sapiens sapiens remains from the late Middle Pleistocene or early Late Pleistocene.

Erat autem ad cuius imaginem faciebat, ad filii scilicet, qui homo futurus certior et verior imaginem suam fecerat dici hominem, qui tunc de limo formari habebat, imago veri et similitudo.
