Analysis of ancient nuclear DNA, recovered from 40,000-year-old remains in the Denisova Cave, Siberia, hints at the multifaceted interaction of human populations following their migration out of Africa.

The new discipline of palaeogenetics is delivering increasing dividends, the latest news coming from Reich, Pääbo and colleagues on page 1053 of this issue. The authors' analysis of nuclear DNA of a human-like finger bone, found in Denisova Cave in southern Siberia, points towards a complex model of migration and colonization after anatomically modern humans moved out of Africa some 50,000–60,000 years ago.

Ever since 1925, when Raymond Dart's report of the first Australopithecus skull in southern Africa upended Victorian views of human origins, there has been debate over whether our species arose only once and spread throughout the world, replacing all extant species of Homo, or whether our ancestors interbred with the other populations and subspecies. The most extreme version of the 'candelabra' model of human origins — according to which human species arose multiple times independently of our Homo ergaster ancestors — has been largely discounted.

But it has been difficult to assess more nuanced models, such as the possibility of genetic exchange with some archaic populations, including Neanderthals, and now perhaps ancient Siberians. Until recently, genetic data and interpretation of the fossil record seemed to favour a complete-replacement model, in which all human species trace all of their genetic ancestry to a single origin in one or more African populations of moderate size some 200,000 years ago2, 3, 4, 5. However, the Denisovan nuclear genome sequence, along with that of Homo neanderthalensis published by some of the same authors6, suggest that the out-of-Africa population history of Homo sapiens is probably much more intertwined than previously thought, with more intertwining in some parts of the world than others.

Triangles and circles respectively represent sampling locations of Neanderthal remains and of present-day human genomes. The blue arrows indicate generally accepted major migrations of anatomically modern humans, following their departure from Africa 50,000–60,000 years ago. At this time, there were two primary archaic species in Eurasia, Neanderthals and Homo erectus; Reich, Pääbo and co-workerssuggest that a third group was also present, represented by the ancient Denisovan genome. From ancient DNA, they identify additional putative events involving two episodes of limited gene flow: first, genetic admixture from Neanderthals to modern humans, shortly after the exit from Africa; second, subsequent admixture with the archaic population exemplified by the nuclear DNA extracted from the Denisova finger bone. This second event seems to affect only the ancestors of present-day Melanesians, who are thought to have colonized Papua New Guinea some 45,000 years ago. African populations, both past and present, are genetically highly diverse, as indicated by the multiple labels.

Native Hawaiians and Native Americans
Part One

In a previous post, "On the Trail of Spider Woman," we suggested that petroglyphs in Arizona and Utah with female goddess symbolism and birthing ceremonies were connected with the Hohokam ("Sea Peoples") and other Indians who followed in their wake, corresponding to archeology and anthropology's Basketmaker Culture. In this and a series of posts over the next few months, we will show pictures of “emergence” petroglyphs from Hawaii, New Guinea, California, Hopi, Zuni, Pima, Papago, Fremont, Zuni, Mimbres, Palavayu and Eastern Woodlands cultural sites that support our thesis. We believe them to be the footsteps and stepping stones of female haplogroup B and its associated lineages.

Mitochondrial Haplogroup B does not have as its dissemination center Mongolia or Siberia or Central Asia but Southeast Asia, specifically Taiwan and Indonesia, and is characteristic, in contrast with Indian groups emphasizing A, C and D, of the Pueblo Indians and some Southeastern Indians such as the Cherokee and Chickasaw and Choctaw. It entered the Americas in successive waves, some of them seaborne, over many millennia.

The first picture comes from the western coast of the island of Hawaii. It is considered one of the oldest religious shrines in the Hawaiian Islands. It shows a stick figure carved into a rock set in the ground. As we will see, this is a typical "emergence" figure marking the arrival of a people in a new phase of existence. The symbolism is of a female mother figure giving birth, her progeny here depicted by the taillike extension coming from between her legs. There are thousands of variations of this tribal or clan mother iconography scattered over Asia and the Americas (but not apparently found in Europe or Africa).

The Hawaiians considered the western coast of the Big Island their place of emergence. According to their legends, their people came from the sea from the southwest and were noted for their ability to twist plants and fibers into ropes. Their capital was hence called Hilo (twisted, plaited). On account of their subtlety in these arts they adopted the hula (twist) dance as their national dance. Its original purpose was as a fertility ritual to increase population. (Johannes C. Andersen, Myths and Legends of the Polynesians, Tokyo:  Tuttle, 1969.) The main song sung during the enactment of the hula was called The Water of Kane, or Waters of Life.

The Hawaiian Mother symbol illustrated above seems to be connected with a certain clan. As is often the case, the head of the female figure is differentiated to show which clan. This one has horns and could represent a dragonfly. This insect recurs in American Indian petroglyphs where it is associated with the Water Clan and fertility rites. To "read" the Hawaiian petroglyph properly we might say, "Here is the spot where the Head Mother of the Water Clan emerged and gave birth to her people." It is likely (although no legends are preserved regarding its use) that women made offerings here to become fertile, attract husbands and be delivered of healthy children. In similar ceremonial sites, such figures mark an actual birthing stone where women squatted to give birth, attended by midwives and clan mothers.

To show the physical resemblance of the Hawaiian design to American Indian symbols we will reproduce  thumbprints below from different traditions. They will be linked together and explicated in subsequent posts in this series.

Abstract

The Philippines exhibits a rich diversity of people, languages, and culture, including so-called ‘Negrito’ groups that have for long fascinated anthropologists, yet little is known about their genetic diversity. We report here, a survey of Y-chromosome variation in 390 individuals from 16 Filipino ethnolinguistic groups, including six Negrito groups, from across the archipelago. We find extreme diversity in the Y-chromosome lineages of Filipino groups with heterogeneity seen in both Negrito and non-Negrito groups, which does not support a simple dichotomy of Filipino groups as Negrito vs non-Negrito. Filipino non-recombining region of the human Y chromosome lineages reflect a chronology that extends from after the initial colonization of the Asia-Pacific region, to the time frame of the Austronesian expansion. Filipino groups appear to have diverse genetic affinities with different populations in the Asia-Pacific region. In particular, some Negrito groups are associated with indigenous Australians, with a potential time for the association ranging from the initial colonization of the region to more recent (after colonization) times. Overall, our results indicate extensive heterogeneity contributing to a complex genetic history for Filipino groups, with varying roles for migrations from outside the Philippines, genetic drift, and admixture among neighboring groups.

A blogger on Eupedia's genetics forum has deduced the haplogroups of many European kings and queens from living descendants who have been tested. It has long been known that mtDNA haplogroup H dominated the lines of Europe's aristocracies, while Y chromosomal R1b was the most common male lineage. Prince Phillip exhibits the stereotypical genes in this regard. More interesting than the royal personages listed are those that haven't yet made the list, like Elizabeth I or Charlemagne. It would be interesting to know what the mitochondrial DNA was of Elizabeth's mother Anne Boleyn or what Charlemagne's male lineage was.

One fascinating observation of the blogger is, "All kings of France supposedly belonged to haplogroup G2a3 (Y-DNA)." G2a makes up 5 to 10% of Mediterranean Europe but is rare in Northern Europe. It is believed to have originated with metalworking peoples from the Caucasus or Anatolia who accompanied the R1b-dominant Indo-Europeans on their conquest of Europe in the 3rd millennium BCE.

See "Geographic Spread and Ethnic Origins of European Haplogroups - Eupedia."

And Now in the Cherokee...

Haplogroup N1a became prominent in genetics literature when Wolfgang Haak et al.'s studies on 7500 year old skeletons in Central Europe revealed that 25% of the Neolithic European population might have belonged to this lineage. The skeletons were found to be members of the Linear Pottery Culture (LBK ware) which is credited with being the first farming culture in Central Europe.

7,000 Year-Old Linearbandkeramik (LBK ware) from Stone Age Germany.

The study was a major development in the debate on the origin of European populations, since Haak et al. argued that "The discovery of mitochondrial type N1a in Central European Neolithic skeletons at a high frequency enabled us to answer the question of whether the modern population is maternally descended from the early farmers instead of addressing the traditional question of the origin of early European farmers."

1. Demic diffusion (in which farming is brought by farmers), for example Renfrew's NDT - Anatolian hypothesis
2. Cultural diffusion (in which farming is spread by the passage of ideas), which is the assumption in Alinei's Paleolithic Continuity Theory.

The study's authors concluded: "Our finding lends weight to a proposed Paleolithic ancestry for modern Europeans."

N currently appears in only .18%-.2% of regional populations. It is widely distributed throughout Eurasia and Northern Africa and is divided into the European, Central Asian, and African/South Asian branches based on specific genetic markers. Exact origins and migration patterns of this haplogroup are still unknown and a subject of some debate.

Although not one of the classic Native American lineages (A, B, C, D, and X -- Schurr), N has been identified in the ancient Southwest in the Fremont Culture centered in Utah. It is one of the Middle Eastern lineages that appear in the Cherokee and other Indians; see DNA Consultants Blog, “Anomalous Mitochondrial DNA Lineages in the Cherokee”. Most investigators attribute this phenomenon to recent European admixture. But such haplotypes  if only instanced in North America without exact Old World matches could just as well be considered Native American.

It has been suggested that N is also characteristic of the Sea Peoples, who may have traveled to the American Southwest in antiquity.

Cherokee or Saponi Wedding Dish from Southwest Virginia in author's possession is glazed black, the color of the Earth Mother, and marked with the "tri-line" signifying the Triple Goddess's power of increase and plenty and rule over all life. The style of pottery is similar to Linearbandkeramik (LBK) ware. This is the female dish of a matched pair. The slightly larger male dish is marked with four lines on each handle. They were used to share food in a wedding or bonding ceremony.
