last but not least- HOW WOULD THEY REPOPULATE THE EARTH!
Because we are classified as Homo sapiens sapiens, the message is that humans today are taxonomically different from the other hominid species you cite. However, the other Homo sapiens subspecies e.g. H. s. idaltu, and H. s. neanderthalensis (sometimes considered a distinct species), which are both extinct forms, are thought to have coexisted with H. s. sapiens.newhope101 said:It appears to me that the Homo subspecies of Homo eragater, homo erectus, homo antecessor, homo heidelbergensis, homo sapiens, are all just humans with adaptive differences such as we see in the world today.
It isn't that science is looking to "build a case for evolving from apes," but it's where the evidence points. Unlike many pseudosciences, such as creationism/intelligent design, science doesn't start with conclusions and then pick and choose evidence that supports it. As for "the whole species and subspecies thing," these taxonomic ranks were established long before hominid classification was developed. In the beginning it simply assigned humans to Homo Sapiens.I suspect the whole species and subspecies thing are concepts that have been developed to fit ToE in with the few bones that have been found. Then scientists use this variation as evidence of species progression. This is the only way science can build a case for evolving from apes.
So, someone with a brain almost half our size is just a "differently adapted" human? You have a very interesting definition of human.It appears to me that the “Homo” subspecies of Homo eragater, homo erectus, homo antecessor, homo heidelbergensis, homo sapiens, are all just humans with adaptive differences such as we see in the world today.
This is incorrect. You seem to enjoy repeating this mistake...Fortunately science has been able to go back 25,000 years and DNA sequence the Neanderthal. It appears Neanderthal were human, and no more different to modern humans than we are to each other today.
This is patently false.They mated with ‘humans’ from Africa, therefore achieving the common understanding of ‘species’, in that same species can mate successfully.
So far...Unfortunately science is unable to get DNA from older bones.
This is also false. Subspecies are based on DNA and almost never used for fossils.I suspect the whole ‘species’ and ‘subspecies’ thing are concepts that have been developed to fit ToE in with the few bones that have been found. Then scientists use this variation as evidence of species progression. This is the only way science can build a case for evolving from apes.
Yes, when a scientist is uncertain, she says so.Many of the Homo subspecies are evidenced from a few bones. Hence all the controversy re whom came from who. A world of perhaps and maybe .makes for great science.
You keep repeating this mistake after you've been corrected. Why?Fortunately science has been able to go back 25,000 years and DNA sequence the Neanderthal. It appears Neanderthal were human, and no more different to modern humans than we are to each other today.

You suspect wrong. Species is a core concept in Biology, that was developed to help Biologists understand organisms.I suspect the whole species and subspecies thing are concepts that have been developed to fit ToE in with the few bones that have been found. Then scientists use this variation as evidence of species progression. This is the only way science can build a case for evolving from apes.

Maybe I keep repeating the mistake because so many science mags and journals speak to it. I'm not sure what part of my statement you are disagreeing with. Surely you do not disagree with the Max Planck Institute for Evolutionary Anthropology. If I can't quote from these sort of credentials against yours I really do give up!

Neandertals are the sister group of all presentday humans. Thus, comparisons of the human genome to the genomes of Neandertals and apes allow features that set fully anatomically modern humans apart from other hominin forms to be identified. In particular, a Neandertal genome sequence provides a catalog of changes that have become fixed or have risen to high frequency in modern humans during the last few hundred thousand years and should be informative for identifying genes affected by positive selection since humans diverged from Neandertals.
I do agree with what the Max Planck Institute is saying because what they are saying, if you actually read what they publish, is that Neandertals were not humans and there is greater variation between us and Neandertals as between human populations.The only part of the genome that has been examined from multiple Neandertals, the mitochondrial DNA (mtDNA) genome, consistently falls outside the variation found in present-day humans and thus provides no evidence for interbreeding.
No... more likely you are skimming and then misquoting.Maybe I keep repeating the mistake because so many science mags and journals speak to it.
I don't disagree with the Max Planck Institute... I've actually read what they have to say.I'm not sure what part of my statement you are disagreeing with.

Yes, it does actually... you just have to read it rather than skim it.Here's just one extract below..google 'neanderthal genome project' and there are dozens of references to this research. The site you recommended on another thread does not reflect this information.
NON-Africans.... That means Eurasians... From Ireland to Japan and so on... Not Modern Africans.ScienceDaily (May 6, 2010) — After extracting ancient DNA from the 40,000-year-old bones of Neanderthals, scientists have obtained a draft sequence of the Neanderthal genome, yielding important new insights into the evolution of modern humans.
Among the findings, published in the May 7 issue of Science, is evidence that shortly after early modern humans migrated out of Africa, some of them interbred with Neanderthals, leaving bits of Neanderthal DNA sequences scattered through the genomes of present-day non-Africans.
"We can now say that, in all probability, there was gene flow from Neanderthals to modern humans," said the paper's first author, Richard E. (Ed) Green of the University of California, Santa Cruz.
Green, now an assistant professor of biomolecular engineering in the Baskin School of Engineering at UC Santa Cruz, began working on the Neanderthal genome as a postdoctoral researcher at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Svante Pääbo, director of the institute's genetics department, leads the Neanderthal Genome Project, which involves an international consortium of researchers.
This is not a definitive finding and will need more reserch to confirmThe draft Neanderthal sequence is probably riddled with errors, Green said, but having the human and chimpanzee genomes for comparison makes it extremely useful despite its limitations.
Humans and Neanderthals are not the same species... but very very closely related sister species. Like Coyotes and Wolves or Polar and Grizzly Bears.By analyzing the Neanderthal genome and genomes of present-day humans, Green and his colleagues estimated that the ancestral populations of Neanderthals and modern humans separated between 270,000 and 440,000 years ago.
Really?It appears to me that the “Homo” subspecies of Homo eragater, homo erectus, homo antecessor, homo heidelbergensis, homo sapiens, are all just humans with adaptive differences such as we see in the world today.
No Biologist has "placed floresiensis above sapeins"... for one, phylogeny doesn't work that way, for second, H. floresiensis is thought to have evolved from H. erectus more or less directly.I'm not the scientists that put florensiensis right above sapiens with their tiny brain. I am not the scientist that placed other species, like neanderthalis, with 15% larger brains that modern day humans, as having evolved prior to florensiensis. What size brain do modern pygmies have? How was this explained?...oh I remember 'island dwarfing'..that explanation doesn't explain a tiny chimp brain right above sapiens...yet florensiensis made fires. Have we taught a chimp to do this yet?
I think given that Aborigional Austrailians have yet to be compared in any genetic survey with Neanderthals you should be careful not to jump to conclusions.Re the max planck research..I thought separate species could not always successfully mate. As different as neanderthal were they mated with another species. Modern humans have been found in Australia 60,000 years ago, Mungo man, the time this mating was occurring.
You have yet to give a biological justification for this idea. Given the profound differences there must be something significant behind it.I think the differences in morphology do not necessarily mean much about the human species...it highlights adaptation rather than species change.
In terms of this discussion any species not H.sapiens, usually200,000 years ago or older.Besides what is pre human?
Is someone suggesting that our decendents in 60,000 years will be that genetically different to people today that there would be no fussion between spem and egg to produce viable offspring.Who knows? It would take a significant break in our gene pool to do so though.
Seeing as we already have humans living in such conditions... no, nothing profound morphologically.What if another ice age happened..do you think humans would morph to suit the environment?
I have no idea what you are talking about... we have observed new species evolving several times.So with mico evolution eventually resulting in enough change that a new species evolved is not clear.
No big surprize here... you really should take a remedial biology course.Now science accepts that similar species can interbreed.
Again, I have no idea what you are talking about here.Once again a change from the initial idea of distinguishing one species from another...changed to suit the evidence. If the evidence does not appear to fit in with ToE, what not invent another theory to resolve the discrepency.
Yup... "human" in the sense that it is a member of the Homo genus. Homo means "man" afterall... you will notice they are later called "hominids" wich means any member of our liniage, post Chimpanzee split that is not a Modern Human.Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease. Using statistical analysis on skeletal remains of a well-preserved female specimen, researchers determined the "hobbit" to be a distinct species and not a genetically flawed version of modern humans. Details of the study appear in the December issue of Significance, the magazine of the Royal Statistical Society, published by Wiley-Blackwell.
Due to the relative completeness of fossil remains for LB1, the scientists were able to reconstruct a reliable body design that was unlike any modern human. The thigh bone and shin bone of LB1 are much shorter than modern humans including Central African pygmies, South African KhoeSan (formerly known as 'bushmen") and "negrito" pygmies from the Andaman Islands and the Philippines. Some researchers speculate this could represent an evolutionary reversal correlated with "island dwarfing." "It is difficult to believe an evolutionary change would lead to less economical movement," said Dr. Jungers. "It makes little sense that this species re-evolved shorter thighs and legs because long hind limbs improve bipedal walking. We suspect that these are primitive retentions instead."
What this article is addressing, is the fact that they are a species in their own right, rather than simply deformed Modern Humans as had been argued by some people. (including creationists)
ps... emphasis mine.

Err... I'm pretty sure they have for a while...Now science accepts that similar species can interbreed.
Or... if the evidence doesn't fit with your worldview, why not discard it all so that you can keep believing what you wish?Once again a change from the initial idea of distinguishing one species from another...changed to suit the evidence. If the evidence does not appear to fit in with ToE, what not invent another theory to resolve the discrepency.
here are some good resources on baraminology for those interested:
The last one points out the irony that "baraminology" methods actually show evolution:

Great point. Obviously the whole species thing is a raught. Dogs are dogs, whether or not they're a spaniel or great dane, and can interbreed, yet they are different species. Chimp and human are also different species and cannot interbreed. Evolutionists have really made a mess of this.

You know what a dog is, right?

All the human and neandethal genome projects appears to have proven is that chimps are human and we're lucky we're not sponges. .. and many living creatures carry identical genes as one would expect to see in a creation...a signature through all of Gods works. Living creatures do not show graduating genetic similarity depending on branching...and you all thought these projects would seal ToE. Scientific testing advances have thrown ToE into turmoil. A bit of real science makes a differnece.
The whole species thing is so vague and unclear that evolutionists, not unlike creationists, can make whatever they want of it. Here's another stupidity I stumbled on in another thread about the okapi.
Palaeotragus ("Ancient Antelope") was a genus of very large, primitive okapi from the Miocene of Africa.
Palaeotragus primaevus is the older species, being found in early to mid-Miocene strata, while Palaeotragus germaini is found in Late Miocene strata.
P. primaevus is distinguished from P. germaini by having no pair of ossicones. It was also the smaller species, being a little under 2 meters at the shoulders. P. germaini had a pair of ossicones, and in life, it would have resembled either a short-necked, 3 meter tall giraffe, or a gargantuan okapi.
So the common ancestor of the giraffe and okapi is the palaeotragus. Palaeotragus is an ancient antelope and primitive okapi. Talk about not putting all your eggs in one basket. And surprise what great scientific rule was used for the classification,,oh yeah..okapis neck length..so it's a giraffe decendent, disregarding totally different chromosome numbers. All this is nonsense.
What does this mean? Why would you expect to see any particular set of circumstances in "a creation?" If a magic being magically made various creatures, couldn't they have similar genes or different genes or no genes at all? Why would you predict any particular arrangement of that? Do you not understand the precise predictions that ToE makes about genetic similarity, and exactly how those predictions were borne out? What is your gripe about Palaeotragus primaevus? Why is this discovery a stupidity to you? I'm sure you have no idea what various factors caused scientists to classify them in the way they did, and what is your objection?many living creatures carry identical genes as one would expect to see in a creation
