I am willing to stipulate a split, but was it really that long ago? Are you thinking in terms of a thousand generations of "genetic drift" or something like that? Maybe it came suddenly as a result of isolation and inbreeding?

The split had been established at something in the 350,000 year range based on the fossil record.

Just in the last week or so I saw an article, I think here on FR, that suggested a split a little earlier based on genetics. They placed that in the 400,000 year range.

I would take that with a grain of salt to start with, until more data comes to light but it seems that the evidence is heading toward an early split at this point.

Certainly the mtDNA tests that were done suggest no close relationship or interbreeding.

Posted back in August:

Are You Part Neanderthal?

"People of European descent may be 5% Neanderthal, according to a DNA study that counters the view that modern humans left Africa and replaced all other existing hominids."

The researchers agree with recent studies that conclude Neanderthals did not contribute any mitochondrial DNA, or mtDNA, genetic material that is passed from mothers to children.

But they say other portions of the European genome, such as those associated with nuclear DNA, may still harbour the Neanderthal imprint.

Plagnol says different parts of the genome have different ancestry, so an individual could have a fraction of a certain chromosome that is inherited from a Neanderthal, but then possess "very typical Homo sapiens mtDNA".

The scientists are not certain which early human group could have contributed to West African DNA, but both Europeans and Africans in the study showed about the same 5% archaic contribution.

Interesting. Thanks!

The original post here involved a claim that neanderthals merged straight into modern humans, which is clearly untenable. As far as humans AND neanderthals both being descended from some third party more primative than either, that is clearly nonsensical; the neanderthal has been ruled out as a human ancestor precisely because the genetic gap is too wide and you're proposing that we must therefore be descended from something with an even wider gap.

That's like claiming that a 243 is too small to hunt rhinos with and I should therefore go out after rhinos with a 22.

Wrong. See the chart below.

In the back of my mind, is the memory of an article--popular science stuff--that explains modernity as the result of infantilization, with the moderns retaining the relatively large skull of the infant. That would make the Neanderthal types our ancestors and collateral cousins.

I think the infantilization was to permit a large brain through a small birth canal. The trick is to have a long infancy during which most of the brain growth occurs.

It will take more than this to show that Neanderthals were our ancestors.

The small face and jaw are also a feature of human infants. From what I have seen of Neanderthal infants, it was also true of them. Females normally have such features and if somehow these can be fixed in the males we have something approximating homo sapiens. IAC, I am bothered by so much specuation based on skimpy evidence. Extrapolations from present data, in either direction, is chancey, especially if it is driven by a philosphical agenda.

I agree. That's why I don't take what creationists say about evolution seriously. They don't know the data, and they wouldn't believe it if they did.

Out for a few hours (work to do).

Once you mate with Ayla you can never go back to Neanderthal women.

When you get back, what do you know about dog populations. It is amazing that so many different shapes could come from the original wolf population. How come so much variety? I will be looking for answers.

I was reading an article about Neanderthal taking a 180. Some people see the DNA of Neanderthal as being distinct and different from humans. The Orlando paper confirms the DNA of an 100,000 specimen to be similar to the 12 other studies. I think that the Neandetrtal DNA shows the Neanderthal was not related to humans. Has anyone said what percentage of DNA is similar? They say that a chimp has over 90% the DNA of humans but I see that as being not related. A carrot has 70-80% of the DNA of a human so does that make us descendants of a carrot? These prehuman monkeys had no great cities and cured no deceases and did not make it to the moon so I do not see them as human.

What do you mean "wrong"?? Your chart shows precisely the thing I claim, i.e. both neanderthal and us descending from something more primative than either, despite the neanderthal having been ruled out as a plausible ancestor for us because he was too primative.

Heck, I can't keep up with all the name changes for dinosaurs. What happened to the Brontosaurus?

It's the new (mistaken) name, that was resolved probably before you'd even heard of it. Apatasour is the original (and current) name.

I disagreed. Now you write:

Lets take this a step at a time. You originally wrote:

But now you write

Your chart shows precisely the thing I claim, i.e. both neanderthal and us descending from something more primative than either.

It sounds like you are coming around to agree with me.

Here is the chart again showing both H. sapiens and Neanderthal descending from an earlier common ancestor:

Cro are modern humans, just an earlier flavor.
