  The Neandertal Story
Early Neandertal fossils exhibit a rounder occipital and a rounder, receding frontal compared to Homo erectus.
It is clear that Neandertals used their teeth differently, perhaps in ways similar to modern Eskimo who also utilize their front teeth to grip things.
Paabo and his coworkers used the mitochondrial control region of the 30 kyr Neandertal 1, (kept at the Rheinisches Landesmuseum in Germany), and then copied and amplified that genetic material, (consisting of 379 base pairs), with the help of two human primers that matched the beginning of the Neandertal sequence.

  The expert Neandertal mind
Neandertals may not have been quite capable of doing nuclear physics or calculus; however, it is a travesty of the available data to argue that they did not have the full complement of basic human faculties or act in recognizably modern fashions (Hayden, 1993: 137).
Neandertals would truly have been experts of their local domain, so much so that new arrivals would be hard pressed to compete.
Neandertals would have been fully capable of learning and mastering any basic stone-age technology, including prismatic core technique (indeed, it is quite possible that their level of technical expertise could learn any modern technological activity).

 Fossil Hominids: mitochondrial DNA
The Feldhofer Neandertal fossil, thought to be between 30,000 and 100,000 years old, was therefore pushing the limits for this kind of work.
The diversity of the three Neandertal mtDNA sequences (3.73%) is lower than that of chimpanzees (14.82+/-5.7%) and gorillas (18.57+/-5.26%), and similar to that of modern humans worldwide (3.43+/-1.22%).
Interestingly, the mtDNA sequences from the Vindija Neandertals, which have a less extreme Neandertal anatomy than the classic Neandertals, and are considered transitional between modern humans and classic Neandertals by some scientists, were no closer to modern humans than the rest of the Neandertal fossils.

 ENSI/SENSI Papers & Articles:DNA + Neandertals
Neandertals, named after the German valley (Neander Tal) where their fossil remains were first discovered in 1856, are extinct hominins (formerly "hominids") that lived in Europe and Western Asia.
Neandertal skeletons suggest they were a larger and more muscular version of modern man with low foreheads, protruding brows, poorly defined chins, and large noses with broad nostrils.
For the conclusion that Neandertals do not contribute to modern gene pools to be correct, it is necessary for the known human sequences to be an accurate representation of the event in question.

 Washington University anthropologist sets record straight on Neandertal facial length
After compiling the data for different groups of hominids, Trinkaus concluded that the Neandertal's overall facial projection was, if anything, average for a Pleistocene epoch sample and was similar to or even modestly reduced from their non-Neandertal archaic predecessors.
First, the majority of the more complete Neandertal skulls that anthropologists have thus far unearthed happen to be those of large males, each of whose facial length scales with the rest of their body.
Trinkaus says there is also the influence of "time's arrow" — that is, for most of the last century, Neandertals have been compared primarily with recent humans and not to their own predecessors.

 100,000 year-old DNA sequence allows new look at Neandertal's genetic diversity
By recovering and sequencing intact DNA from an especially ancient Neandertal specimen, researchers have found evidence suggesting that the genetic diversity among Neandertals was higher than previously thought.
Neandertals were the only representatives of the genus Homo in Europe during most of the last 300,000 years, becoming extinct shortly after the arrival of modern humans on the continent around 30,000 years ago.
The Neandertal specimen analyzed consists in a molar of a 10-12 year-old child that lived in the Meuse valley (Scladina cave, Belgium) around 100,000 years ago.

 DNA Shows Neandertals Were Not Our Ancestors
The team, however, found that Neandertals and modern humans diverged genetically 500,000 to 600,000 years ago, suggesting that though they may have lived at the same time, Neandertals did not contribute genetic material to modern humans.
To check that the amplified DNA was really Neandertal, the researchers prepared primers based on their extracted sample and ran them on numerous human DNA samples.
When the researchers looked at the Neandertal sequence with respect to 994 human mitochondrial DNA lineages including Africans, Europeans, Asians, Native Americans, Australians and Pacific Islanders, they found the number of base pair differences between the Neandertal sequence and these groups was 27 or 28 for all groups.

 Iodine deficient?
Neandertal’s brutish brow and other features are identical to an iodine-deficient human condition called cretinism.
Neandertal, who looked very human but was burly and stocky, developed a far less sophisticated culture than Cro-Magnon, the first modern humans in Europe, who emerged about 40,000 years ago.
If Neandertal did suffer an iodine deficiency, either through a dietary dearth or physiological inability to extract it, it would have spread through generations because iodine is very important to fetal development.

 Technology Review: How Neandertal DNA Will Shed Light on Human Genes
He was able to infer that Neandertals and homo sapiens came from a common ancestor and split approximately half a million years ago.
The biggest challenge in actually sequencing the DNA is the fact that 95 percent of the genetic material in a Neandertal bone is microbial--from ancient bacteria.
In order to generate three billion bases of Neandertal DNA [about the length of the genome] we'll need to generate 20 times more bases of sequence, for a total of 60 billion bases for this project.

 Recovery of Neandertal mtDNA: an evaluation
The implication is that the Neandertals did not evolve into fully modern humans, that they were a different species from modern humans, and that they were just one of many proto-human types that were failed evolutionary experiments.
That Neandertals and anatomically modern humans were buried together constitutes strong evidence that they lived together, worked together, intermarried, and were accepted as members of the same family, clan, and community.
The fact that Neandertal and modern human sequences are approximately equidistant from the chimpanzee outgroup seems to be a good indication that Neandertal and modern humans comprise one species.

 Neandertal Coalescence   (Site not responding. Last check: 2007-11-07)
If the human sample was not present as a reference we would argue that the german neandertal had a transversion at position 60 of the Croat sequence (ancestral to german sample), recently (since no other mutations are indicative of differences between croat and german neandertal).
That, in order for the previous 'explanation' to be valid, then the 'trunk' of Neandertal had to also have a transversion at position 60, IOW the german sequence was the result of a reverse transversion of the croat sequence.
There are a number of differences between human and common to all neandertal that fall on the neandertal side of the branch, thus we can seperate the A to C event from the C to A event by as many as 11 transitions, 1 transversion and one insertion (061).

Although this date must be qualified (it is based on one specimen only, and the DNA clock may or may not be as accurate as we assume), it is in accord with the fossil record.
The relationship between Neandertals and modern humans, who are thought to have arisen in Africa some 120,000 to 150,000 years ago, and the demise of the Neandertals are intertwined.
