Inconsistencies With Neanderthal Genomic DNA Sequences
Science Daily — Were Neanderthals direct ancestors of contemporary humans or an evolutionary side branch that eventually died out?
This is one of the enduring questions in human evolution as scientists explore the relationship of fossil groups, such as Neanderthals, with people alive today. Two recent papers describing the sequencing of Neanderthal nuclear DNA from fossil bone held promise for finally answering this question [1, 2].
However, the two studies came to very different conclusions regarding the ancestral role of Neanderthals. Jeffrey D. Wall and Sung K. Kim from University of California San Francisco now reveal in PLoS Genetics what they found when they reanalyzed the data from the two original studies.
Wall and Kim's reanalysis reveals inconsistencies between them and they believe that possible contamination with modern human DNA and/or a high rate of sequencing errors compromised the findings of one of the original Neanderthal DNA studies.
The authors therefore recommend that we carefully evaluate published and future data before arriving at any firm conclusions about human evolution.

GGG Ping.
Makes you kind of wonder about the accuracy of any gene sequencing....
Some interesting observations:

Buried Alive: The Startling Truth About Neanderthal Man
by Jack Cuozzo
Anyone who has met my ex mother-in-law would know that the Neanderthal species is still alive
Or the results didn’t match what they wanted to find.
Not really. The older you go the more difficult it gets.
Living individuals are easy.
lol

What, no GEICO cavemen pictures??
That show is pretty funny BTW. I was surprised at how lowkey the humor is and very very dry wit. But some really funny references/jokes for thirty something’s.

A picture of Harry Reid would convince me that Neaderthals still roam the globe
The Neandertal EnigmaFrayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

Thanks Blam. Of course, the myth that a study was done showing Neandertal is an extinct cousin will persist. |

So where do Adam and Eve come into things?
Oh Yeah...I keep seeing vestigial neanderthals all the time too.
They are with us.
It's all intuitively obvious.
Now, sit down and be good. The Creos only claim the last 6500 years, if that, and all the rest of time is left to the Evos.
The Evos are working on the answer. The Creos are not concerned.
I’m only buzzed, but I have no idea what you’re talking about.
=D
Chips? (holds out bag).
