there is really no trait in neanderthal not found in homosapiens.

these differences don't make a different taxa.
they could be different because all ancient humans were like that or because they were an extinct race of humans.
or the most likely they are still alive as the Europpeans russians (big noses, big arches, etc minor traits to conform to weather no need for dna change for that at all)
all humans proven by DNA branched from a man who lived 50k years ago.
so there can't be humans before that.

if my watch tells me a specific time has passed(dna), you can't counteract with counting how many sunrises has passed(gravel guessing).
it is sharp.
these traits dont make a different taxa. they could happen inside homosapiens.
for example a person with a flat sniffers nose needs only 80 years of special stressor (like extreme cold) to make his nose caucasian pointed, and no need for dna changes for that to happen.
The Neanderthal were caucasian race of the homosapiens and they still live as the caucasian race.
only three percent of their dna survived the ages, and that 3 percent is what is found in current humans.
when a person dies third of his dna mutate in the first hour.
passing several thousand years the only dna on a bone is the dna of thousands of generations of germs lived on the bone ever since.
comparing dna of neanderthal with current humans is not scientific .
they should compare dna of neanderthal with dna of humans contemporary or as old and from the same area., then you will see that they match with all their dna since 97% belong to germs and 3% belong to humans (humans and their branch the caucasian race)

you don't provide citation that Science was inherited by you from Mr Darwin, and I dont
the 1.8Mya are chimps like darwin.
Only maternal dna could survive after several k years. Maternal dna can not possibly change because they are responsible for life functions. they should match 100% percent between humans and neanderthal.
since the obvious similarities of both, having same life functions.
to match only 3% is yet another evidence that the dna is that of the germs (lives even to the deepest places in bones.
germs make colony and die another germ make colony over the dead bodies of dead colony and so on.
dna germs should match for geographical areas. they change after weather change too.
On average, Neanderthal mtDNA genomes differ from each other by 20.4 bases and are only 1/3 as diverse as modern humans (Briggs et al. 2009). The low diversity might signal a small population size, possibly due to the incursions of modern humans into their range (Briggs et al. 2009).
in forensic medicine you could tell where the bone was found (australia or sweden) just from germs dna, and you could tell they are older or younger than 5k years because of the change of the germs flora.

Later, Svante Pääbo’s lab sequenced the entire mitochondrial genome of five Neanderthals (Briggs et al. 2009). Sequences came from two individuals from the Neander Valley in Germany, Mezmaiskaya Cave in Russia, El Sidrón Cave in Spain and Vindija Cave in Croatia. Though the Neanderthal sample comes from a wide geographic area, the Neanderthal mtDNA sequences were not particularly genetically diverse.
they compared neanderthal from central asia with homosapien bones from africa.
The Neanderthal mtDNA sequences were substantially different from modern human mtDNA (Krings et al. 1997, 1999). Researchers compared the Neanderthal to modern human and chimpanzee sequences. Most human sequences differ from each other by on average 8.0 substitutions, while the human and chimpanzee sequences differ by about 55.0 substitutions. The Neanderthal and modern human sequences differed by approximately 27.2 substitutions. Using this mtDNA information, the last common ancestor of Neanderthals and modern humans dates to approximately 550,000 to 690,000 years ago, which is about four times older than the modern human mtDNA pool. This is consistent with the idea that Neanderthals did not contribute substantially to modern human genome.
