Recently discovered bones and stone tools dating back 2.12 million years
show that human ancestors left Africa much earlier than had been
previously thought.

Discovery of ancient tools in China suggests humans left Africa earlier
than previously thought

"Ancient tools and bones discovered in China by archaeologists suggest
early humans left Africa and arrived in Asia earlier than previously
thought.

The artefacts show that our earliest human ancestors colonised East Asia
over two million years ago. They were found by a Chinese team that was
led by Professor Zhaoyu Zhu of the Chinese Academy of Sciences, and
included Professor Robin Dennell of Exeter University. The tools were
discovered at a locality called Shangchen in the southern Chinese Loess
Plateau. The oldest are ca. 2.12 million years old, and are c. 270,000
years older than the 1.85 million year old skeletal remains and stone
tools from Dmanisi, Georgia, which were previously the earliest evidence
of humanity outside Africa.

The artefacts include a notch, scrapers, cobble, hammer stones and
pointed pieces. All show signs of use‹the stone had been intentionally
flaked. Most were made of quartzite and quartz that probably came from
the foothills of the Qinling Mountains 5 to 10 km to the south of the
site, and the streams flowing from them. Fragments of animal bones 2.12
million years old were also found."

Wait. The Georgian find is variously identified
as habilis, erectus, some sort of proto erectus
or a different species/population entirely. And,
they have often been touted as proof (or at least
evidence) of "Out of Asia" over "Out of Africa."

Note:

The problem here is that all these finds are
above sea level, and sea level began dropping
around 3 million years ago with the formation
of the Isthmus of Panama and the creation of
mountain glaciers. So, it's entirely likely
that the true home of these populations was
somewhere currently under water. That, we aren't
looking for the first humans in Asia/Pacific,
much less inspecting their remains. These would
be the descendants of the first, homos who
later moved inland.
