  Homo Genus   (Site not responding. Last check: 2007-10-22)
Homo is the genus that includes modern humans and their close relatives.
Homo neanderthalensis, traditionally considered the last surviving relative, died out 30,000 years ago while recent evidence suggests that Homo floresiensis lived as recently as 12,000 years ago.
Through that species, Homo is next most closely related to the group of extinct species in the genera Paranthropus and Australopithecus, whose evolutionary branch split off from the proto-Homo line some 5 million years ago.

 Genus Homo
Homo habilis was named so because the artifacts found with the fossils were rudimentary stone tools that had been created from rocks.
Homo erectus spread from the area of southeast Africa throughout Europe, Asia, and the Indonesian Islands that were not surrounded by water at the time.
Homo sapiens was so successful that he spread beyond the bounds of erectus and even made it to Australia on a land bridge during one of the ice ages.

 Homo rudolfensis
The species designation of Homo rudolfensis is a much debated topic, over both whether it is a separate species, and if it is an australopithecine rather than a member of the genus Homo.
The research team involved (led by Richard Leakey) attributed the toothless cranium to the genus Homo with the species indeterminate due to the large brain size and questionable morphological association with known hominids.
Homo rudolfensis may be the first member of the genus Homo on a path to modern humans, or it may be a more Homo-like australopithecine with no direct bearing on the evolution of H.

 Homo- Leakey Ancestors
The earliest secure evidence of the genus Homo is piece of upper jaw recently discovered at Hadar, in the Awash Valley, Ethiopia, dated at 2.33 million years.
Similarly it was believed that a single exodus of Homo erectus from Africa led to the emergence of Homo neanderthalensis, which later gave rise to Homo sapiens.
The Homo lineage is characterised by the development of technology, from the initial manufacture of stone tools for specific purposes 2.5 million years ago to the rapid and exponential technological advances that we see today.

 Human Origins and Intelligent Design
Homo habilis is said to show brain enlargement, the first usage of primitive stone tools, and the origin of a humanlike bipedal pelvic gait.
Homo habilis was found to be australopithecine in all of its major characteristics—body size, body shape, locomotion, jaws and teeth, development, and brain size.
This strengthens the case that Homo habilis is not a species of intermediate morphology between australopithecines and Homo, as it lacks reliable criteria connecting it to modern humans, or establishing it as a link between australopithecines and Homo.

 Homo erectus - Leakey Ancestors
Another Homo erectus cranial character is the 'occipital bun', the distinct bun-shaped protrusion at the back of the skull.
New dates suggest that Homo erectus reached Java sometime between 1.8 and 1.6 million years ago, and a Homo erectus mandible from Dmanisi in the Georgian Republic is believed to be of a similar age.
Later it was realised that the similarities with Homo sapiens were close enough that Pithecanthropus erectus should be included within the genus Homo, although the differences from H.

 Human Ancestors Hall: The Homo Habilis Debate
It was once thought that the evolution of the genus Homo was an example of anagenesis, the continual and gradual change of one parent species into its daughter species in a linear fashion.
Another debate centered around Homo habilis and Homo rudolfensis is whether or not these two species belong in the genus Homo or would be better suited in one of the other hominid genera.
This would make Homo a monophyly (all species evolved from a common ancestor), rather than a polyphyly (the species evolved from more than one ancestor) as it is now thought to be.

 Human Ancestors Hall: Homo habilis
In the 1960s, many researchers argued that Homo habilis was not a valid species, and that the fossils attributed to H.
There is much debate as to the number of species that existed in Homo 2 million years ago, and KNM ER 1470 is now assigned to the species Homo rudolfensis.
Homo habilis was originally thought to be the ancestor to all later Homo.

Goodman's paper cites a proposal by George Gaylord Simpson that chimps and gorillas be combined in one genus - gorillas are in the genus Gorilla.

 Origin and Evolution of the Genus Homo   (Site not responding. Last check: 2007-10-22)
The differences between Homo habilis and Australopithecus are: homo habilis possesses a greater cranial capacity(610 to about 800cc), it has reduced prognathism- a flatter face and a shorter tooth row.
Homo habilis has limbs still reminiscent of apes in terms of their relative proportions.
Homo habilis is also thought to have possessed a locomotion more human in attributes than that of the australopithecines.

 Early Human Evolution:  Early Transitional Humans
The evolution of the genus Homo and the robust australopithecines beginning around 2.5 million years ago coincides with the beginning of a prolonged cooling climate trend in East Africa.
In fact, it is beginning with Homo habilis that our ancestors finally had brains that were consistently bigger than those of the great apes.
However, the body size of Homo habilis was not significantly larger than the early hominids that preceded them.

Hominines tend to have larger brains, smaller teeth, and more human-like limb proportions than their ancestors, although among themselves they have a real assortment of tooth, brain, and face size.
The genus Homo contains the earliest hominids found outside of Africa: members of Homo erectus were living in western Asia between 1.8 and 1.2 million years ago, and in Europe by 800,000 years ago.
The genus Homo is famous for the greatest and most rapid increase in the ratio of brain size to body size that has ever occurred in mammalian evolution (70% in 700,000 years during the Middle Pleistocene), the earliest evidence of tools and other artifacts, the domestication of fire, and the first art and personal adornment.

 Earliest Remains of Genus Homo
Because the jaw is sufficiently different in morphology from other known early Homo fossils, however, Kimbel and his team have yet to assign it to a species.
afarensis and better understand what happened between the demise of that species and the emergence of the Homo line." Abundant antelope fossils found in association with the jaw and tools suggest that the Afar region was an open grassland 2.33 million years ago, a marked contrast to the area's dense woodland environment during Lucy's time.
Since the transition from Afarensis to Homo took place between 2.33 and 2.9 million years ago, some researchers have suggested that such climate change may have triggered rapid evolutionary adaptation.

Characteristic features in the only 6.1 cm high and 3.9 cm broad fossil indicate the genus Homo: a globular forehead and hind skull and an inferior position of the occipital hole under the cranium, which is typical for upright body posture.

With that close a relationship, the two living chimp species belong in the genus Homo, says Morris Goodman of Wayne State University in Detroit.
The closeness of relationship between chimps and humans has become an important issue outside taxonomy, becoming part of the debate over the use of chimps in laboratory experiments and over their conservation in the wild.
Classifying chimps as human might raise their conservation profile, but Harcourt hopes that is not the only way to get people to worry about them.

The Homo genus is separated from the earlier hominids because of the emergence of tool use, language, and culture.
The characteristics of these species are bigger brain (above 1000ml), the forehead rises straight up, the skull becomes rounder, the teeth are reduced, arms are shorter and legs are longer, and the skeleton becomes more delicate.
Some important features about it is that it was stronger than Anatomically Modern Homo sapiens and that he had a narrow spinal cord, which may have inhibited speech.
