Do humans share 98% of the same DNA as Chimps?

What about Neanderthal Man?

roughly, it's about the amount we share with fruitflies and moluscs as well.

Mr vicks & JTW,

Indeed. Such a fact is among the clearest arguments for the validity of evolution by common descent, variation, and natural selection.

Doctor Who says:
Actually, it runs deeper than that.

Europeans have about 4% Neanderthal DNA, Asians have about 2% and Africans have about 1% if I remember the numbers correctly. The DNA of Neanderthals even includes the same gene foxp2 indicating they also had language, etc.

Dr Who -- I think that Africans have no Neandertal DNA

The DNA that is shared or identical is 97.8% or nearly 98% as already indicated. Many other similarities also exist as well. Almost identical skeletal structures can be found in both modern H. sapiens and the typical quadrupedal primate. The Pan troglodytes or chimpanzee skeleton has all the same skeletal structures that can be observed in modern humans. There is a clear and distinct pattern of evolution taking place. This can also be observed in behaviors including the exhibiting of empathy. Primates including orangutans will also demonstrate the use of tools and actual tool making to achieve a goal. The making of crude weapons have also been observed in primates. The genome mapping of all animals including primates and H. sapiens illustrates the direct connection genetically.

andhorsie,

You can maintain your ancient and outmoded "God created all of it" stance all you want. Science moves forward while you are still looking back and holding onto outmoded thinking. Maybe you should continue to think that the sun revolves around the Earth and that the Earth is the center of the universe. That would fit in well with your persona.

A study of history should tell you that religion and religious thinking more often than not gets everything a**backwards. It is still stuck in the 1st century or earlier.

Doctor Who,

A minor correction: that Neanderthals had the foxp2 gene needn't indicate they had language but, rather, at least had some precursor brain structure necessary to language. They worked stone exquisitely and that talent requires the same brain structures as language. If it's possible, researchers should be able to attribute some consistent symbolism to neanderthal artifacts; that would more strongly suggest a language capacity.

To some extent I think this raises the question of exactly when a "language" arises out of a series of hoots, grunts, and gestures within a certain situation.

andthe...,

Please present evidence of a new species miracled into existence.

But, I suppose, you could claim that "god" caused the original conditions that led to the evolution of all life. In that case, your argument loses by Occam's Razor: "god" has become an unnecessary element in the process.

I was going to guess James Carville but, then, you'd have to explain Mary Matalin.

i'm sure she'll appear more and more lifelike as 3D printing improves.

The only problem with the "god" created the original conditions is that this "god" is a human construct. There is no evidence for any kind of specific god. There is no independent evidence that is not directly linked to humans creating it. For example, dinosaur fossils exist on their own merit without any interference or creation by humans. Everything about "god" is all deeply attached with humans. Everything about this god always comes from humans. If we found a gigantic metal slab (i.e. 2001 A Space Odyssey) on the moon which was speaking to us in many different languages saying this was created by the Christian god. Then that would exist on its own merit without obvious human intervention or being created by humans. There is no independent evidence for any god causing anything. All the evidence and observations are natural and nothing supernatural has ever been observed.

Doctor Who says:
Actually, I was surprised at that. Apparently there are trace amounts.

In this nova, they explore they show the tests and found that there was some present in Africans.

J. Deen says:
It should be mentioned that, despite the similarities in DNA, you can still do a differential analysis. Neanderthals, for example: despite being so similar to us, neanderthals are still several times father away from us than any living human is from any other living human.

J. Deen,

All modern humans today have DNA that is 99.5% identical. The DNA of an Asian is 99.5% identical to an African, American Indian or a European etc...and vice versa. It is that .5% that makes us all different in terms of appearance etc...

<Dave vicks says: Do humans share 98% of the same DNA as Chimps?>

Kind of indicates that DNA may not be all it's made out to be. Are we to imagine that the mind of man is in that 2% difference?

Re Arjuna, above: "not one single positive mutation has ever been found..." Factually inaccurate. See:
