Skip to comments.New finds in Caucasus suggest non-African origin for ancient Homo species
Posted on 06/07/2011 5:39:10 PM PDT by SunkenCiv
Early members of the genus Homo, possibly direct ancestors of people today, may have evolved in Asia and then gone to Africa, not vice versa... new evidence shows the species occupied a West Asian site called Dmanisi from 1.85 million to 1.77 million years ago, at the same time or slightly before the earliest evidence of this humanlike species in Africa, say geologist Reid Ferring of the University of North Texas in Denton and his colleagues...
Evidence remains meager for the geographic origins of the Homo genus, says anthropologist Bernard Wood of George Washington University... and it's possible that humankind's genus got its start in Asia with H. erectus.
Researchers have abandoned the long-standing view that a small-brained hominid from East Africa known as Homo habilis, which first appeared about 2.4 million years ago, evolved into H. erectus. Recent fossil finds showing that the two species coexisted in East Africa for several hundred thousand years have undermined that assumption...
Wood regards H. habilis fossils as apelike enough to be reclassified as part of the Australopithecus lineage, which includes a more than 3-million-year-old species represented by a partial skeleton known as Lucy...
The new Dmanisi discoveries come from just beneath soil that previously yielded 1.77-million-year-old H. erectus fossils, including skulls with surprisingly small brain cases suggestive of an early form of the species (SN: 9/22/07, p. 179). Excavations produced 73 stone tools for cutting and chopping, as well as 34 bone fragments from unidentified creatures. The artifacts came from a series of H. erectus camps at Dmanisi between 1.85 and 1.78 million years ago, the scientists say.
Measurements of reversals in Earth's magnetic field and of the rate of decay of the element argon in a series of volcanic ash layers provided age estimates for the new finds.

Were ancient human migrations two-way streets? (Assoc Press source)
I thought the homo species originated in San Francisco.
More like ‘out of Africa - to somewhere else - to everywhere else including Africa’.
But, but what about the homeland??? What about Mother Africa??? That’s ok, at least the Kenyan was from there.
Well Calypso Louie does say that the white devil was created by a mad scientist in the caucasus.
homo erectus, as we now know, evolved AFTER Tweeter

Image: JOHN GURCHE PORTRAIT OF A PIONEER With a brain half the size of a modern one and a brow reminiscent of Homo habilis, this hominid is one of the most primitive members of our genus on record. Paleoartist John Gurche reconstructed this 1.75-million-year-old explorer from a nearly complete teenage H. erectus skull and associated mandible found in Dmanisi in the Republic of Georgia. The background figures derive from two partial crania recovered at the site.
Oh yeah...that's right, it's me.
This is where man came from!!
I give up! Every time an article on this subject comes up, my minds eye sees Adam and Eve changing their appearance.
New fossil reveals primates lingered in Texas

The timing of molar emergence and its relation to growth and reproduction in apes is being reported by two scientists at Arizona State University's Institute of Human Origins in the Dec. 28 online early edition of the Proceedings of the National Academy of Sciences (PNAS). From the smallest South American monkeys to the largest African apes, the timing of molar development and eruption is closely attuned to many fundamental aspects of a primate's biology, according to Gary Schwartz, a researcher at the Institute of Human Origins and an associate professor in the School of Human Evolution and Social Change in ASU's College of Liberal Arts and Sciences... Because of the difficulties in obtaining tooth emergence ages from animals in the wild, Kelley opted for other means; he searched for specimens in museums. At the Zoologische Staatssammlung in Munich he found skulls of a wild-shot orangutan (Pongo pygmaeus pygmaeus) and gorilla (Gorilla gorilla gorilla) that preserved emerging first molars... the two scientists were able to mark the age of the gorilla's first molar emergence at 3.8 years, nearly identical to that of a wild chimpanzee's. The orangutan's age at first molar emergence was surprisingly much later, at 4.6 years, which falls closer to the age of approximately 6 years in modern humans... However, he and Schwartz caution that though the later emergence age in these large Asian apes is closer to that for modern humans, these latest findings should not be taken to indicate some special evolutionary relationship between the two.
I really wish I knew what "reversals" in Earth's magnetic field means. Personally I 'believe' there was a time when due north and magnetic north were in unison and there will come a time when the two are set back in alignment.
Now the notion 'origins' is not 'out' of Africa is almost enough to shake this old earth back into its original orbit.
The Scars of Evolution:"The most remarkable aspect of Todaro's discovery emerged when he examined Homo Sapiens for the 'baboon marker'. It was not there... Todaro drew one firm conclusion. 'The ancestors of man did not develop in a geographical area where they would have been in contact with the baboon. I would argue that the data we are presenting imply a non-African origin of man millions of years ago.'"

Early Homo erectus Tools in China

Is the basis for the “Out of Africa” theory around because they really haven’t found anything anywhere else?
Once the Arctic ice all melts next year and we can see what is up there maybe they’ll find all kinds of things.
Just cause they found stuff in Africa doesn’t mean there isn’t other evidence all over the world.
And to really remove any doubt, why don’t they just ask HT? She would know.

It’s linked up there somewhere.
That’s correct. And because there are some nicely preserved strata that are close to the surface, the whole out-of-Africa bias amounts to the punchline of that old joke, the guy lost his glasses inside the dark restaurant, but he’s looking around outside because the light’s better.
Reversals in the Earth’s magnetic field means, the magnetic poles of the Earth have shifted in short amounts of time, and many more times than once or twice; and the shifts (which are recorded in ferrous rocks that used to be molten lava) are not related to continental drift.
I’d hit it.
That is a female right?
I always thought Homos originated in San Francisco.
Large changes of the earth's magnetic fields in historical timesBy measuring the magnetic properties of bricks and other accurately dated human artifacts, geophysicists can reconstruct the history of the local magnetic field. Near Loyang, China, the field was as much as 54% higher in 300 A.D. than it is now. It was 15% higher in 1500 A.D. In 1000, it was less than today's value.

(Wei, Q.Y., et al; "Intensity of the Geomagnetic Field near Loyang, China, between 500 BC and AD 1900," Nature, 296:728, 1982.)
Comment. Direct measurements of the earth's field go back only a few hundred years, but they are consistent with the data reconstructed from artifacts, both showing a steady decrease since 1500. No one has estimated the effects of these substantial changes on radiocarbon dating and, perhaps, human biology.
[old note of mine I saved from another topic] Since the magnetic pole shifts in the fossil record don’t seem to be uniformly spaced, at all, the cause of them is probably external. Since I was a Boy Scout (hard to believe, I know) the magnetic north pole has moved hundreds of miles.
I knew civilization started in North Texas. ;-)
Damn homos, they go back a long way!
You're bad! You're gonna get in trouble!
But, you're right. Homes didn't come from North Texas. They came from San Francisco.
I can’t say that I ever gave a lot of credence to that “out of Africa” business. I think one reason it was so rapidly accepted was that it was, well, politically correct.
Really ... and when they said ancient homos, I expected a picture of Bawney Fwank.
No time scale. There is evidence of intervals as short as 50,000 years, with others as long as 10 million years. Seemingly random.
Does this mean that we`re not all Egyptians after all?

“Once the Arctic ice all melts next year and we can see what is up there maybe theyll find all kinds of things.”
We can just ask the nuclear sub captain parked under that ice.
God owned a nursery somewhere.
Bet he had some breeding stock as well.
Like he would tell us? Even if I said I was his mother I think he would ignore us.
Didn’t originate there; migrated there from Sodom, just before the destruction of the cities. The “City By The Bay” reminded them of the “The Cities By The Sea”.
Thank you for your helpful response. I do remember the 2004 Indian Ocean earthquake causing a measurable shift of this earth, and then again with the recent quake near Japan. What I have not read is which direction from polar north the earth shifted.
Re: magnetic reversals. This site gives a pretty concise explanation of it.
I think the big earthquakes nudged the earth’s axis of rotation? I don’t think they affected the earth’s magnetism.
The Japan earthquake this year actually moved the whole island by over a meter. (slid it closer to the mainland, I believe).
Thank you for the link. I think I will have to read this more than one time to get a better grasp of what has happened and appears to continue to take place.
I just found a nice reference in the book, “A Crack in the Edge of the World” (about the San Francisco earthquake of 1906) by Simon Winchester (p. 70-71) about the magnetic reversals. I think it is in one of his other books, about the mapping of the field reversals across the sea floor that show the seafloor spreading (it is leaving “stripes” across the ocean floor). Go to your library and grab a few Simon Winchester books (”Krakatoa”, “The Map that Changed the World”, and “The Crack....”). He explains plate tectonics really simply. Another book I’ve loved is John McPhee’s “Annals of the Former World” which talks about island chains like Japan squishing into North America and basically creating California.
Get ready for an NAACP lawsuit.
There once was a man named McTavish
Who attempted an anthropoid ravish;
In his haste for the rape
He grabbed the wrong ape
And the anthropoid ravished McTavish!
