Lantian Man hominin

New dating of Homo erectus skull reclassifies Lantian Man as oldest known hominin in northeast Asia

(Read the article on one page)

Lantian Man is the name given to subspecies of Homo erectus of which ancient fossils were found in Lantian County, Shaanxi Province in China in 1963.  Lantian Man were originally dated to 1.15 million years. However, a new study published in the Journal of Human Evolution , has provided compelling evidence that the fossil is actually 1.63 million years old, making it the oldest fossil hominin ever found in northeast Asia, and its original location the second oldest site with cranial remains outside Africa.

The first remnant of Lantian Man that was found was a mandible (jaw bone) at Chenjiawo in Lantian County. Shortly after this discovery, a cranium (skull) with nasal bones, right maxilla, and three teeth of another specimen of Lantian Man were found at Gongwangling, another site in Lantian County. The cranial capacity is estimated to be relatively small at 780 cubic centimetres.

The new age of Lantian Man was obtained through highly detailed research carried out over 12 years (2001 – 2013), which utilized latest methods including loess-palaeosol stratigraphy, tectonic-geomorphology, sedimentology and mineralogy, geochemistry, palaeontology, paleomagnetism and rock magnetic methods. They also analysed thousands of other samples found in the area. 

"This age is consistent with the geological context and the subtropical fossil fauna at Gongwangling, and also the small-brain size of the Gongwangling Homo erectus cranium, similar to that seen in Georgia and Indonesia", said HUANG Weiwen, a professor of the nstitute of Vertebrate Paleontology and Paleoanthropology of Chinese Academy of Sciences in Beijing, as reported on Phys.org.

According to the researchers, the new dating of Lantian Man suggests that Homo erectus moved eastwards in warm period that occurred just after 1.75 million years ago.  They may also have followed southern routes from Africa into Asia, as evidenced by the presence of fossils in Indonesia that are only slightly younger (c. 1.5 – 1.6 million years).

"The revised age extends its age by about half a million years and makes the Gongwangling site a crucial benchmark in establishing the framework of the origin, migration and dispersal of early man in the Old World", said Robin Dennell of University of Exeter in United Kingdom, "It also provides reasonable evidence for re-evaluating the status of other early and controversial human fossils in China and Java. In addition, this new research rewrites the history of the Lantian hominin and provides additional knowledge of human evolution for the public".

And the rest of us get so tired of these half-thought-out theories.

Honest

This proves that the so called human migration from Africa does not make sense.

I hope they now re-evaluate other early and controversial fossil remains in China and Java as well now.  Of course there will have to be revisions as noted by JA Bosworth and at some point it is going to have to be accepted that proto-humans emerged separetly in Asia even if the only surviving humans originated in Africa as he says above.  I personally believe that not only did proto-humans emerge separately in Asia but survivors exist even today from that lineage.  I don't buy the Out of Africa completely theory!  

 

It seems that the dates for proto-human migration from Africa will need revision, because fossils found in Eurasia are older than the current consensus.
It also seems increasingly clear that proto-humans emerged separately in Asia, even if the only surviving humans originated in Africa.

The south-pointing chariot is a Chinese invention that functioned in a similar way to a compass. Instead of pointing north, however, this device could point south, or any other direction it was ‘programmed’ to point in the first place, for that matter. The compass, which is regarded as one of the Four Great Inventions of the Chinese civilisation, functions based on the Earth’s magnetic field.

During the Early Woodland Period (1000—200 BC), the Adena people constructed extensive burial mounds and earthworks throughout the Ohio Valley in Ohio, Indiana, Pennsylvania, Kentucky, and West Virginia. Many of the skeletal remains found in these mounds by early antiquarians and 20th-Century archaeologists were of powerfully-built individuals reaching between 6.5 and eight feet in height (198 cm – 244 cm).

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
