The timing & route of the earliest dispersal from Africa to E-Asia are
contentious topics in the study of early human evolution : Asian hominin
fossil sites with precise age constraints are very limited. Here we report
new high-resolution magneto-stratigraphic results that place stringent age
controls on excavated hominin incisors & stone tools from the Yuanmou Basin
SW.China. The hominin-bearing layer resides in a reverse polarity
magneto-zone just above the upper boundary of the Olduvai subchron,
yielding
an estimated age of 1.7 Ma.
The finding represents the age of the earliest documented presence of Homo,
with affinities to H.erectus, in mainland E.Asia. This age estimate is
roughly the same as for H.erectus in island SE.Asia , immediately prior to
the oldest archaeological evidence in NE.Asia.
Mammalian fauna & pollen obtained directly from the hominin site indicate
that the Yuanmou hominins lived in a varied habitat of open vegetation with
patches of bushland & forest on an alluvial fan close to a lake or swamp.
The age & location are consistent with a rapid southern migration route of
initial hominin populations into E-Asia.

They assume that erectus-like people dispersed from Africa to Asia, but
this
is wishful thinking,

= the only "argument" of our little boy,

Says the pervert who thinks mountain beavers are semi-aquatic.

who is too stupid to realise that

Speculation is not hard evidence.

- Gona is probably hominid,

Now this idiot does't even understand the differenence between
artifacts and
speculation.

"Spatially associated zooarchaeological remains show that hominids
acquired meat and mar-
row by 2.5 million years ago and that they are the near contemporary
of
Oldowan artifacts at nearby Gona. The combined evidence suggests that
be-
havioral changes associated with lithic technology and enhanced
carnivory may
have been coincident with the emergence of the Homo clade from
Australo-
pithecus afarensis in eastern Africa."

"The World¹s Oldest Stone Artefacts from Gona, Ethiopia: Their
Implications for Understanding Stone Technology and Patterns
of Human Evolution Between 2·6­1·5 Million Years Ago"


Abstract
"The systematic archaeological and geological survey and excavations
at Gona between 1992­1994 led to the discovery
of well-flaked stone artefacts which are currently the oldest known
from anywhere in the world. More than 3000 surface
and excavated artefacts were recovered at 15 localities documented
east and west of the Kada Gona river. Based on
radioisotopic dating (40Ar/39Ar) and magnetostratigraphy, the
artefacts are dated between 2·6­2·5 million years ago
(Ma). EG10 and EG12 from East Gona are the most informative with the
highest density, providing the best
opportunity for characterizing the oldest assemblages and for
understanding the stone working capability of the earliest
tool makers. Slightly younger artefact occurrences dated to 2·4­2·3 Ma
are known from Hadar and Omo in Ethiopia,
and from Lokalalei in Kenya. Cut-marked bones dated to 2·5 Ma from
Bouri in Ethiopia are now providing important
clues on the function of these artefacts. In addition,
Australopithecus garhi known from contemporary deposits at Bouri
may be the best candidate responsible for the oldest artefacts.
Surprisingly, the makers of the Gona artefacts had a
sophisticated understanding of stone fracture mechanics and control
similar to what is observed for Oldowan
assemblages dated between 2·0­1·5 Ma. This observation was
corroborated by the recent archaeological discoveries
made at Lokalalei. Because of the similarities seen in the techniques
of artefact manufacture during the Late
Pliocene­Early Pleistocene, it is argued here that the stone
assemblages dated between 2·6­1·5 Ma group into the
Oldowan Industry. The similarity and simplicity of the artefacts from
this time interval suggests a technological stasis
in the Oldowan."


but re"troviral data are about our ancestors,


"About" is lip sevice. Where is your evidence?
