Protein sequence from Neanderthal extracted and sequenced
An international team, led by researchers at the Department of Human Evolution, Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, have extracted and sequenced protein from a Neanderthal from Shanidar Cave, Iraq dating to approximately 75,000 years old. It is rare to recover protein of this age, and remarkable to be able to determine the constituent amino acid sequence. This is the oldest fossil protein ever sequenced. Protein sequences may be used in a similar way to DNA, to provide information on the genetic relationships between extinct and living species. As ancient DNA rarely survives, this new method opens up the possibility of determining these relationships in much older fossils which no longer contain DNA (PNAS Online Early Edition, March 8, 2005).
The research, published in PNAS, presents the sequence for the bone protein osteocalcin from a Neanderthal from Shanidar Cave, Iraq, as well as osteocalcin sequences from living primates (humans, chimpanzees, gorillas and orangutans). The team found that the Neanderthal sequence was the same as modern humans. In addition, the team found a marked difference in the sequences of Neanderthals, human, chimpanzee and orangutan from that of gorillas, and most other mammals. This sequence difference is at position nine, where the crystalline amino acid hydroxyproline is replaced by proline (an amino acid that is found in many proteins). The authors suggest that this is a dietary response, as the formation of hydroxyproline requires vitamin C, which is ample in the diets of herbivores like gorillas, but may be absent from the diets of the omnivorous primates such as humans and Neanderthals, orangutans and chimpanzees. Therefore, the ability to form proteins without the presence of vitamin C may have been an advantage to these primates if this nutrient was missing from the diets regularly, or from time to time.
This research opens up the exciting possibility of extracting and sequencing protein from other fossils, including earlier humans, as a means of determining the relationships between extinct and living species, and to better understand the phylogenetic relationships.

It's all lies! Those scientists are making it all up because they hate Christ! :lol:

ââ¬â Cardinal Bellarmino, 1615, during the trial of Galileo[/QUOTE]I'm not sure what the motivation is, but I know the genetic sequences with Neanderthal and Homo Sapiens have been run: they don't match. Neanderthal is a different branch of hominid.
Believe it or not, there has been a lot of politically correct handwringing over "ruthless" Cro-Magnon exterminating innocent Neanderthal. I watched some bitter bull dyke anthropologist fulminating about this on TV.
I'm not sophisticated enough to discern it, but I suspect this latest method and finding is along the lines of the geneticists who analyze down to the molecular level, and declare they can't find a "race" gene. (I.e., there is no "white" hydrocarbon, therefore race must be a social construct.)
I suspect the genetic findings on Neanderthal have suggested some things about race and outcomes that the science establishment, overwhelmingly made up of Democratic net tax consumers, does not want to hear. Therefore, they will change the method until they get the conclusion they want.

How does a finding that a Neanderthal protein sequence is the same as modern humans a blow to anything other than Evolution? Many non-evolutionists have long held that neaderthals are just humans. Evolutionists have strongly resisted admitting that neanderthals are humans.

One set of priests have been replaced by another set of priests (albeit godless) as the overseers of "science." Both sets of priests gained their religious beliefs from atheists. Cardinal Bellarmino would have done better reading the Bible than reading Ptolemy for his religous beliefs. BTW, what point were you trying to make? PS, you have another thing in common with Bellarmino. You both think the Bible doesn't belong in school and would probably prefer that the common man not have access to the Bible.
