Why Ius The Homo Florewnsis Not A Modern Human

Floresiensis does not change the broad picture of human evolution including our lineage - it was certainly not ancestral to us. Interestingly local legends exist in Flores of the Ebu Gogo small hairy cave dwellers similar in size to H.

The leg bones are thicker than those of modern humans.

Why ius the homo florewnsis not a modern human. As a result when walking they would have had to have bent the knees further back than modern humans do. An artists interpretation of how H. Hobbit species did not evolve from ancestor of modern humans research finds This article is more than 3 years old Bone study shows there is no evidence the 11-metre tall Homo floresiensis had.

It is suggested that perhaps the hobbits survived longer in other parts of Flores to become the source of these stories. Since this is the only location where this species has been discovered we may never know their link to Homo sapiens. Floresiensis although there is no evidence of this at Liang Bua.

The wrist bones in particular show themselves to be of pre-modern structure. Semantics aside the tiny stature of 110cm for the Hobbit Homo floresiensis female type is well below the recorded range for modern humans pygmy or otherwise. This evidence contradicts the earlier claim of an entirely modern human-like dental morphology of H.

Floresiensis while at the same time does not support the hypothesis that H. The poor Hobbit was accused of being an example not of a small new human species but an abnormal Homo sapiens bearing any of a variety of growth and hormonal conditions. The Hobbit many scientists decided had no place among the giants of the human evolutionary record.

Critics have argued the specimen belonged to an extinct human with microcephalia a pathological condition characterized by a small head the hobbit is estimated to have a brain about one-third the. For an extinct human species 12000 years ago is crazy recent modern humans were building permanent settlements and monuments by then. They were also different from the bones of modern humans.

Floresiensis may have resulted from island dwarfisman evolutionary process that results from long-term isolation on a small island with limited food resources and a lack of predators. However subsequent follow-ups including by the Smithsonian Institution found the skeleton was not a human suffering from microcephaly and possesses a distinct wrist-structure to be expected from a proto-human and would not be reflected in any type of. Florensiensis is not a modern human with an undiagnosed pathology or growth defect but that it represents a species descended from a hominin ancestor that branched off before the origin of the clade that includes modern humans Neandertals and their last common ancestor.

Modern humans arrived in Indonesia between 55000 and 35000 years ago and may have interacted with H. This evidence also suggests that H. It turns out the sensational dates were wrong.

Various attempts have been made. This caused a high-stepping gait and low walking speed. While her entire body is small the proportions of her various skeletal parts are those of an ancient hominid species and not the proportions specific to modern humans.

Continued excavations and analysis showed the hobbit fossils derive from sediment layers between 60000 and 100000 years old. Floresiensis looked in life. Homo floresiensis was thought to have co-existed with modern humans in the region for tens of thousands of years.

Floresiensis was more similar to early humans and apes than modern humans. But since it is the most extreme example of human adaptation ever found it suggests that humans are more subject to evolutionary forces than we tend to think. However more recent excavations and analyses show this not to be the case.

Apparently they have not recovered any workable DNA from the bones discovered on the Island of Flores. It appears that the hobbit may have become extinct just before or just after modern humans arrived on the island. The discovery of H.

A study of the bones and joints of the arm shoulder and legs also concluded that H. There is no substance to these claims. Due to their combination of plesiomorphic unique and derived traits they were ascribed to a new species Homo floresiensis which along with Stegodon appears to have become extinct 17 ka thousand years ago.

Another consideration regarding Flos stature is her locality. Pygmy elephants on Flores now extinct showed the same adaptation. The diminutive stature and small brain of H.

Because the initial Homo floresiensis skeleton was so amazingly small for a human relative there was initial suspicion that it was a hoax or a person suffering from microcephaly a medical condition that produces a small head and brain. Close analysis shows that Homo floresiensis is not only a genuinely new species but that its closest affinities lie with Plio-Pleistocene African species such as Homo habilis so that it documents an earlier dispersal of hominins from Africa and had hitherto been suspected. The fossils were dated to between 100000 and 60000 years ago with their stone tools dating to between 190000 and 50000 years ago.

The feet were unusually flat and long in relation with the rest of the body.
