People were in the Americas at least 15,000 years earlier than previously thought

I’ve always thought the peopling of the Americas was more complex than DNA evidence would have us believe. The ice retreated and advanced many times. Who knows how many times various clans wandered into the “New World” and died out when the ice advanced.  Stone tools discovered in Mexico’s Chiquihuite Cave have pushed back the arrival of the first humans in the New World by, at least, 15,000 years.

Dr Ardelean said: “We don’t know who they were, where they came from or where they went. They are a complete enigma. We falsely assume that the indigenous populations in the Americas today are direct descendants from the earliest Americans, but now we do not think that is the case.

“By the time the famous Clovis population entered America, the very early Americans had disappeared thousands of years before. There could have been many failed colonisations that were lost in time and did not leave genetic traces in the population today.”

A geochemical analysis of volcanic ash found in ice cores from Greenland and Russia suggests that a massive eruptions of Okmok circa 43 BCE may explain a period of cold and famine at the end of the Roman Republic.

Working with colleagues from the U.K., Switzerland, Ireland, Germany, Denmark, Alaska, and Yale University in Connecticut, the team of historians and scientists gathered supporting evidence from around the globe, including tree-ring-based climate records from Scandinavia, Austria and California’s White Mountains, and climate records from a speleothem (cave formations) from Shihua Cave in northeast China. They then used Earth system modeling to develop a more complete understanding of the timing and magnitude of volcanism during this period and its effects on climate and history.

According to their findings, the summer and fall following the blast may have been as much as 13°F colder than normal. It was, also, a lot wetter. It was also responsible for failures of Inundations of the Nile in late Ptolemaic Egypt, causing widespread famine and disease.

Nerdly Things: Neandertals, Denisovans, Music and Fishing

new&nerdlyRemember that fossil from Sima de los Huesos who looked something like a Neandertal, but whose mtDNA caused such a stir because it was so Denisovan? Well, while Mama’s family seems to have ummm, played with others, Dad’s side of the family was definitely more closely related to Neandertals than any other species. This is according to an analysis of its nuclear DNA. This has huge implications for the timing of the genetic split between the three species and pushes back the origins of Neandertals as a distinct species as well.

Speaking of Denisovans, it looks like they used the cave which gave them their name longer than previously thought. The initial discovery of a finger bone from a little girl has been dated via DNA to about 50,000 years age. Teeth found in the cave, and also belonging to Denisovans, were those of individuals who died 110,000 and perhaps 170,000 years ago. Moreover, these people don’t appear to have been all that closely related to each other.

Apparently, the folk memory preserved in Aboriginal songs goes back a really long time. As in at least 7,000 years. Certain geographical references in the songs point to the fact that they, in their current forms, were being composed just as the Australian coastline was just beginning to take on its modern shape.

People have been fishing for salmon in the Pacific Northwest for at least 11,500 years.

Philistine impacts on Levantine agricultural practices

new&nerdlyThere’s been lots of coverage about the changes and adaptations the Philistines made to traditional South Levantine agricultural practices.

In a previous study (Ancient DNA and Population Turnover in Southern Levantine Pigs- Signature of the Sea Peoples Migration? – Scientific Reports), it was determined that European wild boars were introduced into the Southern Levant during the Iron Age, presumably by the
Philistines and/or other elements of the so called “Sea Peoples” migration. This new study focuses on flora instead of fauna. Including the introduction of opium poppies, cumin, and sycamore trees. These plants come from such varied places as Egypt and Mycenaean Greece. The Philistines also gave new uses to plants already found within Israel such as bay trees and coriander.

Just as fascinating was the appearance of apricots and European wild nettle in non-Philistine areas of Israel. Both of these species come from Iran. Who brought them, I wonder? This study opens up all kinds of possibilities in using plant matter discovered during excavations to study ancient migration events.

Some Nerdishness

new&nerdlyThey’ve discovered a Mycenaean palace near Sparta, complete with “archaic inscriptions.” Always love when new inscriptions are found.  One thing, though:

…excavations in the area have unearthed inscriptions on tablets detailing religious ceremonies and names and places in a script called Linear B, the oldest script to be discovered in Europe. It first appears in Crete from around 1375 BC….

I thought Linear A, also written in Crete, was older than Linear B.

A new study talks about how much more diverse large mammals would be, outside of Africa, if humans never existed. Think about it. In North America alone we had, just off the top of my head, two species of mammoths, at least one of mastodon, and three of bison plus horses and camels, two or three species of lions, cheetahs, dire wolves, cougars, jaguars, short-faced bears, and sloths. Of all of those only cougars, one or two jaguars in Arizona, and one species of bison remain. And the jaguars are a recent development.

Apparently those odd boulder mortars of the Natufian culture served a funereal function similar to modern church bells. Not sure I entirely agree with this.

A huge cache of some 500 cave lion bones belonging to 5 or 6 beasts has been found in a Siberian cave along with a giant cave bear skull pierced with a spear. There were also a few weapons, all Mousterain (a Stone Age tool technology usually associated with Neadertals), found in the cave, but no evidence that people actually lived in it. It’s likely that this cave had some sort of religious significance. Preliminary, guesstimated, dates between 30,000 and 60,000 years ago.

Neolithic Warfare and other Nerdly Items

new&nerdlyFirst, a look at those studies on First American DNA published last month from a Siberian perspective.

Some more early human bones found in yet another Siberian cave not all that far from Denisova.  What type of early human/s has yet to be determined, but researchers are hoping for the full Altai triumvirate of Denisovan, Neandertal, and anatomically modern human.

More evidence solidifying the overall impression of internecine violence at the end of the Linear Pottery culture (LBK), including evidence of torture (the thing with the teeth) and the mutilation of corpses to cripple the victims in the afterlife, possibly to prevent them from effectively haunting their attackers.

… the second in what is now Ukraine.  This temple is located within a large settlement that was part of the Trypillian cultural sphere.  I think the remarks about similarities between this complex and temples in Eridu are a bit far fetched and based on superficialities.  Unless, of course, those similarities go deeper than those this article implies.

There’s an interesting, very sciency, article in the online journal Nature Communications about cultural transitions in the Greater Hungarian Plain and corresponding changes in the genetic makeup of the population.  What most of the less technical sites got out of it was that Europeans drank milk and ate cheese long before they developed the genetic mutation that lead to lactose tolerance, allowing for maximum use of the nutrition provided by dairy products.

Lots of coverage of, and different spins on, genomic data gained from a 45,000 year old thigh bone of an anatomically modern human found in Siberia.

In other genomic news, there is evidence that the Polynesian inhabitants of Rapa Nui, better known as Easter Island, interacted, and interbred, with people from South America at a surprisingly early date.  Just as intriguing, was another discovery mentioned in the article:

… a second article that will appear in the same issue of Current Biology by Malaspinas along with Eske Willerslev and their colleagues examined two human skulls representing the indigenous “Botocudos” of Brazil to find that their genomic ancestry is Polynesian, with no detectable Native American component at all.

I remember reading about this super-eruption of Campi Flegrei a few years ago.  Now they’re saying that the impacts of the eruptions on the areas inhabited by Neadertal populations was minimal.  Comparable to the environmental impacts of the 1815 eruption of Mt. Tambora on the same areas.  Which, to my mind, seeing as how both eruptions rate 7 on the VEI scale, how Campi Flegrei is considered a super-eruption, and Tambora is not.

Some early signs of habitation have been found in Canada. Underwater, of course. I doubt it’s really the “earliest”, though. I hate when they use unnecessary superlatives. Especially when they’re, probably, untrue and definitely misleading. If you’re going to be that dramatic (and, being the media, of course they will) at least tack on the phrase “yet found”.

This one, about innovation in ancient humans, is getting a lot of press, but it just screams “Duh!”, to me.  I mean, even ancient humans/hominids were, well, human.  They probably made all sorts of innovations and discoveries where ever they were.  This particular technological leap was just so common sense practical, that people thought of it in several places and it radiated out from those places because of it’s common sense awesomeness.

We think of the ecosystems of land and sea as separate entities, but, this study shows that even in the Triassic, this wasn’t so, as monsters from one preyed on monsters of the other.
