This is not to say that kenyanthropus would have been any more human in its behaviour than australopithecus - still less does it mean that the lineage that leads to humans, specifically, can definitively be traced back 3.5m years.
Kenyanthropus has a very similar, flattened face, but is almost twice as ancient as 1470.
At the moment, kenyanthropus adds an exclamation mark to what has been, for some time, the confused state of our understanding of human evolution.

 Did Humans Descend From Lucy Or From Newly Discovered Creature?
The Kenyanthropus platyops fossils were discovered in 1998 and 1999, with the skull found in August 1999 by Justus Erus, a Kenyan research assistant working with Meave Leakey near the Lomekwi River in the western Turkana basin in northern Kenya.
Brown said the Kenyanthropus discovery illustrates that "at almost every time in the past back to 4 million years, there were two or more species of hominid existing on Earth.
Brown, Gathogo and McDougall estimated the Kenyanthropus skull's age by indirectly dating surrounding layers of tuff, which is rock deposited when ash from volcanic eruptions in Ethiopia was carried to the Turkana region by rivers and wind.

Kenyanthropus shows a strange mix of primitive and advanced features indicating that it forms part of a side branch of human evolution which has never been seen before.
Kenyanthropus appears to have evolved from an australopithicine ancestor and the younger Homo ruldolphensis may have evolved from it (which means H.
Kenyanthropus platyops was alive at the same time as at least one other human ancestor (Australopithecus afarensis) and adds weight to the theory that humans have branched out several times during their evolution.

Kenyanthropus displays bone cracking and twisting comparable to that in the most distorted oreodont fossils, White contends.
In his view, Kenyanthropus may actually have been a form of Australothecus afarensis, the 3-million-to-4-million-year-old species that includes the famous partial skeleton called Lucy, which White codiscovered.
The Kenyanthropus skull exhibits extensive cracking but remains symmetrical and thus provides a reliable view of the ancient hominid, Tattersall says.

The study in Nature scrupulously avoids taking a position on which species may be the direct ancestor of modern people.
Brown and Gathogo had suggested Leakey look for fossils in the area where Kenyanthropus platyops ultimately was found because they noticed lots of undisturbed antelope and hippopotamus fossils there, indicating it had not yet been picked over by field crews.

The discoverers, led by Meave Leakey, wife of paleontologist Richard Leakey, say the discovery means that modern humans could have sprung from at least two possible lineages, not one.
Leakey also says Kenyanthropus could replace Lucy as the best candidate on the human family tree for our direct ancestor, but she says neither Lucy nor the new fossil is necessarily "the one."
Kenyanthropus lived at the same time as Lucy, but farther south in an area known today as Lake Turkana, Leakey says.

 Early Humans: University of Utah News Release: March 21, 2001
Discovery of the fossils of Kenyanthropus platyops – meaning flat-faced human from Kenya – will be reported in the March 22 issue of the journal Nature by a team led by paleoanthropologist Meave Leakey of the National Museums of Kenya.
Brown and University of Utah geology undergraduate Patrick Nduru Gathogo co-authored the study, along with Fred Spoor of University College London, Ian McDougall of The Australian National University in Canberra and Christopher Kiarie and Louise Leakey of the National Museums of Kenya.
The smaller molars in Kenyanthropus suggest it probably had a different diet than Australopithecus, so both could have lived in the same area at the same time without directly competing for food, Leakey and Spoor said.

Many extinct hominids have been studied to help understand the relationship between modern humans and the other extant hominids.
Some of the extinct members of this family include Gigantopithecus, Orrorin, Ardipithecus, Kenyanthropus, Australopithecus and Paranthropus.
The exact criterion for membership in the Homininae is not clear, but usually includes the species who share more than 97% of their DNA with the modern human genome, and requires the capacity for language and for simple cultures beyond the family or band.

 New Kenyan Fossil find
Of particular scientific interest amongst the new finds is the reasonably complete skull which was discovered by research assistant Justus Erus who was working with Meave and Louise Leakey near the Lomekwi River, in northern Kenya.
Therefore, the differences between Kenyanthropus and Australopithecus probably show that they had different diets and could have existed side by side without direct competition for food resources.
The team working on the new finds included Christopher Kiarie who carried out the painstaking laboratory preparation of the fossils, Frank Brown and Patrick Gathogo (University of Utah) who studied the earth layers in which the fossils were found, and Ian McDougall (Australian National University) who did the isotopic dating of these layers.

 Skull an Evolutionary Riddle / Leakeys' fossil find in Kenya brings more questions than answers   (Site not responding. Last check: 2007-10-12)
Maeve Leakey named the creature Kenyanthropus platyops -- the "flat-faced man of Kenya" -- because its facial structure is remarkably flat compared with many other fossils in the long line of hominids that leads to modern Homo sapiens.
But in the far distant past, life must have been different for the creatures Leakey calls Kenyanthropus who, she said, resembled large chimpanzees and were just about that size.
That little creature, barely 3 feet tall, was one of a species in the genus known as australopithecines whose remains have been found in many parts of Africa, from the great Rift Valley on the east to the land-locked desert nation of Chad south of Libya.

Though 40 percent of Lucy's skeleton had been recovered in 1974, most of her skull, aside from a lower jaw and a few cranial fragments, was missing, leaving may unanswered questions as to her dentition, facial architecture, and brain size.
