Southern exodus. A trail of stone tools and fossil bones suggests that
early
humans left Africa 1.8 million years ago. Some headed north to Dmanisi,
Georgia; others may have taken a southern route into China and Java,

Over a million years ago, a band of early humans left their stone tools
and
two front teeth near a stream in southwest China. For decades, the precise
age of the fossils has remained a mystery, leaving open a central question
in paleontology: How quickly did our human ancestors reach China after
leaving Africa? Now, thanks to advanced dating techniques, scientists may
finally have the answer. ...
Now, a team of Chinese and American researchers has redated the Yuanmou
Basin site using a paleomagnetic technique that relies on rock samples to
determine the direction of Earth's magnetic field when the rocks were
formed. Although the original hillside where the fossils were found has
been
excavated, the discoverers recorded the layer of sediment where they
uncovered the teeth and tools. The new team traced that sediment layer--or
time horizon--throughout the basin, collecting 318 rock samples from it.
In
an article in press in the Journal of Human Evolution, the researchers
report that the fossils came from a layer of rock just above a magnetic
landmark known as the Olduvai-Matuyama reversal boundary, which is at
least
1.77 million years old. This makes the fossil site slightly younger, about
1.7 million years old.

First occurrence of early Homo in the Nachukui Formation (West Turkana,
Kenya) at 2.3-2.4 Myr ... In 2002 a new PA site (LA1 alpha),
100 m S of the LA1 archaeological site, produced a first right lower
molar of a juvenile hominid (KNM-WT 42718). The rel.small size of the
crown, its marked MD elongation & BL reduction, the rel.position of
the cusps, the lack of a C6 & the mild expression of a protostylid,
reinforced by metrical analyses, demonstrate the distinctiveness of this
tooth compared with A.afarensis, anamensis, africanus &
Par.boisei, and its similarity to early Homo. The LA1 alpha site
lies 2.2 m above the Ekalalei Tuff which is slightly younger
than Tuff F dated to 2.34 ± 0.04 Ma. This juvenile specimen represents
the oldest occurrence of the genus Homo in WT ...
Thanks, Travsky, sensible answer, better than your usual idiocies.
But this has been discussed here already:
Posted before. Like when you claim homo came from Asia...

This "wide belief" (??) is based on nothing: the earliest Homo fossils come
from Mojokerto & Dmanisi. Both in Asia, c 1.8 Ma, the former in a marine
delta & the other also next to rich aquatic resources. The earliest
erectus-like fossils in Africa are less than 1.6 Ma.

Here I am correcting you, also in July.

You were wrong then and you're wrong now.
