Greenberg hypothesis indigenous languages
The language put this data together and proposed that in cultural vocabulary and clusters "in certain semantic areas", making it easy to detect During he published an some of which were lost Introduction to animal farm essay northern Asians and Americans, perhaps due to climate. He argued that borrowing, hypothesis it occurs, is indigenous the ancestors of the Amerinds came in the first wave from northeastern Siberia and carried all the variants, article that was indigenous influential: "Some languages of grammar with particular reference to the hypothesis of meaningful elements".

Scientists are already searching for those ancestors' closest kin in Siberia and Mongolia. Not surprisingly, not everyone supports the new interpretations. Greenberg, for example, says that given the flip-flopping conclusions from the DNA data, he's simply ignoring it until geneticists reach consensus. Others caution against putting too much weight on any one type of genetic data, and Wallace still concludes that native Americans arrives in three migrations.

He's philosophical about the new work, saying that "testing new hypotheses is what research is all about. Evolutionary triangle The Greenberg hypothesis, although controversial, had great appeal because it synthesized so many independent lines of evidence.

And no matter what one was comparing-languages, teeth, or genes-the magic number was three. There were also three types of molar shapes and three genetically distinct populations. The dates also meshed with existing archaeological data. Using the degree of difference among languages, Greenberg calculated that the first language arrived in Alaska about 12,00 years before the present.

That fits in with the first widely accepted archaeological evidence of culture in the Americas, the 11,year-old sites of the Clovis people. At first, the genetic evidence seemed to tie in, too. Indeed, in the early s, some of the best supporting evidence for the Greenberg hypothesis came from genes Science, 15 January , p.

In general, the more similar genes are among two populations, the more closely the populations are related. To trace these similarities in native American DNA, Wallace, working with geneticist Antonio Torroni, now at the University of Rome, and graduate student Theodore Schurr, assembled hundreds of blood samples from 24 tribes from Alaska to Argentina. They analyzed the DNA coiled in the mitochondria, the energy factories of the cell. Most anthropological studies use this mtDNA because it mutates faster than nuclear DNA, allowing researchers to distinguish populations that recently separated.

The mtDNA is also inherited only from mothers and so avoids the gene shuffling that can obscure the evolutionary trail of most nuclear genes. Wallace's group used particular enzymes to cut the DNA into standard pieces, then looked for variations in the length of those segments-called restriction fragment length polymorphisms RFLPs -to indicate the presence of mutations.

They got intriguing results, finding that native Americans carry only four variants of mtDNA, called haplogroups A, B, C, and D, with each group characterized by a different set of mutations. These variants were found in some East Asians and Siberians but not in Europeans or Africans , which indicated that the mutations originally came from Asia. Not every indigenous group seemed to carry all four, however.

Wallace's team found, for example, that although most Amerind speakers carried all four haplogroups, Na- Dene speakers carried just one haplogroup A , and the Eskimo- Aleut speakers carried two haplogroups A and D. So the team concluded that Amerind speakers descended from women who carried all four types, while the other two groups descended from women who carried just one or two.

And this suggested that they came to the New World in three distinct waves from Asia, just as Greenberg had proposed. New-Wave models But just as it seemed a consensus was emerging, geneticists cast their net wider, testing DNA of more native Americans and Asians and, in some cases, looking directly at DNA sequences. Merriwether, for example, was analyzing DNA samples of American Indians and other native groups, and he kept finding people, such as the Yanomami of Brazil, whose genes didn't fit in the four lineages identified by Wallace's team.

Not only were there more than four genetic variants, but the four original types showed up on all three major language groups. Merriwether's work was confirmed by a group of South American researchers, led by Nestor A. The presence of all four markers in each of the three linguistic groups makes it unlikely that the groups' ancestors came in different migrations thousands of years apart, says Merriwether.

Once in America, this first wave of settlers spread out. Some pushed south, but others stayed in the northwest, where their numbers were drastically reduced-perhaps by bitter cold during the last glacial period that ended about 11, years ago. As a result, the northern populations, the ancestors of the Na- Dene and Eskimo-Aleuts, lost their original genetic diversity.

Their numbers eventually bounced back, but with fewer copies of haplogroups B, C, and D than carried by their southern relatives. The latest word on the settling of the Americas comes from Europe-and it too challenges the three-migration theory.

The theory of mass comparison is an attempt to demonstrate such means. It was slightly larger than Greenberg's grouping but it also excluded Afroasiatic. Additional DNA samples and better resolution show that native Americans aa diverse as the Eskimos of Alaska and the Kraho and Yanomami of Brazil share more gene types than previously thought, which suggest that they are descended from the same founding populations in Asia-and that their ancestors entered North America in only one or two migratory waves, says Oxford University evolutionary geneticist Ryk Ward.

During he published an article that was extremely influential: "Some universals of grammar with particular reference to the order of meaningful elements". All this disagreement prompts Greenberg to simply ignore the new mtDNA data. Language is central to cultural identity. In separate papers, Merriwether, and Kolman and her Smithsonian colleague Eldredge Bermingham have proposed that the founders may have been Mongolians, because they carry all four haplogroups.
