Preliminary work: Neanderthals had 99.5% H. Spiens genes,

at least.

Scientists mapping Neanderthal genome.

>> A bone fragment that scientists had initially ignored has begun to yield secrets of the Neanderthal genome, launching a new way to learn about the stocky and muscular relative of modern humans, scientists say.

Genetic material from the bone has let researchers identify more than a million building blocks of Neanderthal DNA so far, and it should be enough to derive most of the creature's 3.3 billion blocks within the next two years, said researcher Svante Paabo....

The two teams basically agree, within their margins of error, that the evolutionary lineages of Neanderthals and modern humans split somewhere around 500,000 years ago, he said. That number had been suggested by far more limited DNA analysis before, so it's comforting to see it backed up with more extensive analyses, he said.

Neanderthals and anatomically modern humans coexisted in Europe for thousands of years, until Neanderthals died out some 28,000 years ago. Scientists have been debating whether the two groups interbred and whether modern humans carry some genetic remnants of Neanderthals....

Rubin also said analysis so far suggests human and Neanderthal DNA are some 99.5 percent to nearly 99.9 percent identical. <<

The key issue will be: which genes are different?

As witnesss, call my old IT support staffers.

Of course if they hadn't been what they were I might have not learned as much.

Considering the number of bone fragment frauds ...

perpetrated by anthropologists how is it KNOWN that the sample is from an actual Neanderthal? It isn't a KNOWN fact, but simply a supposition.

It is said that those on the far left have a percentage similar to that of the Chimp (again it depends on the validity of the "sample").

Chimp DNA runs around 97% of human, but vast amounts of human, and chimp DNA is non-operational. It is the detritus left behind by millions of years of evolution. And it only requires one defective gene on one of 26 chromasomes to produce imperceptible, or mildly or seriously or lethally divergent changes.

The original Neanderthal skeleton has been found, now that there is a lot more material to compare it with, to have been an elderly and gravely arthritic individual, or possibly one with some sort of genetic mis-cue. Neanderthals are now though to have been very similar to **** sapiens, though somewhat stockier, and better adapted to cold climates. It is currently said that if you passed one, dressed in a suit on the street, you probably wouldn't notice, or you might think he needed a chin implant, that's about all.

As the Ice Ages retreated, so did the environment that supported them, and the animals that they hunted. Many Neanderthal skeletons show healed fractures of arms ribs and legs. They lived tough lives and tended to hunt large prey. One of the best sites was in the cave at Shanidar in Iran. The Neanderthal buried there was half blind judging by marks on the skull and facial bones, and paralysed on one side judging from evidence on the limb bones. He was old, perhaps 50 or more, and had been cared for for a long time, possibly decades. He would have had to be carried during travel. He was buried, surrounded by flowers, wrapped in an animal skin cape (sorry, I don't remember the species) and with grave goods including weapons points and a necklace, if my memory is right. All of this indicates good social structure, probably good communication skills, a valuing of individuals despite handicaps, and a successful grouping who could afford a non-productive member or members. It also indicates reverence for the dead, and possibly that they had a concept of the afterlife.

There are a lot of Neanderthal skeletons of greater or lesser completeness, but identifying Neanderthal bones is usually very easy because of their density and their size, both greater than **** sapiens.

The term Cro-Magnon is also tossed around (not here, thank heaven) as a synonym for Neanderthal. It's quite the opposite. In terms of appearance they were virtually identical to **** sapiens sapiens (us) but they had differences in skull morphology and in average height. The men ran well over 6 feet, and the species has been linked to the Irish giants that died out in the 17th or early 18th centuries and commonly exceeded 6.5 feet. The women were proportionately tall as well.

Thanks Dave. Did you catch the news story about the

Roman shipwreck off the Spanish coast in the Mediterranean? It's in 75 meters of water and the cargo is hundreds of amphorae of "gaurum" or fish sauce that the Romans put on everything. The recipe is disgusting: take small fish (sardines), fish guts, salt water, and herbs and allow to ferment in the heat for a couple of weeks or more. Then bottle and serve.

Any way its a large wreck and a large ship much of it buried in the mud and possibly retreivable, and classical archaeologists are quite over the moon about it.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
