You accept that people developed in asia, africa and europe but not here?
Native Americans cannot truly be native?
Hopi legends tell of how we survived many global catastrophe's with help from our brothers and sisters from the stars.
SC: Within environments of extreme cold and extreme heat, life forms that evolve will be severely limited. In more temperate (i.e. life-conducive) climes, however, then all manner of life can evolve - including (for example) one proto-bacteria laying the lineage for non-flowering plants whilst another proto-bacteria elsewhere in a temperate region of the world laying the lineage for flowering plants.
Byrd: Yes. This is what I've been saying for the past innumerable posts,
Byrd: except that we know the differentiation took place after plants more complicated than single celled algae arose and after plants moved from the water to dry ground.
SC: As such I consider it entirely feasible still that consciously aware species (different from but not entirely unlike humans) could have evolved (in parallel) in such circumstances.
Byrd: We'd see the precursor species, then

Evolution is still a theory as is creation. We still have no real proof how exactly we got here. People need to stop referring to theories as if they are fact.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. en.wikipedia.org...

Evolution is fact, it's observable in small scale through ought our life times.
Large scale evolution is theory, however that theory is based on modern understanding of observed evolution coupled with the fossil rcord.
So, it's both fact and theory.
The Eve theory, which has been in vogue for 14 years, implied that no modern human outside Africa, alive or dead, would have an older mtDNA signature than Eve herself. What odds, then, that one of the first mtDNA signatures to be recovered from an ancient Australian skeleton would be older than Eve's?
LM3 is at least 40,000 years younger than Eve. Desiccated blood cells from his bone marrow yielded overlapping, fragmented mtDNA that, when digitally reassembled with a Silicon Graphics supercomputer, revealed a signature both unique, yet oddly familiar.
Part of LM3's ancient mtDNA signature survives in a small minority of living human beings - not in their mitochondria, but inserted in one of their chromosomes.
Mitochondrial DNA sequences in ancient Australians
Sequences from the lineage that includes LM3’s mtDNA no longer occur in human populations, except as the nuclear Insert on chromosome 11. The fact that LM3’s morphology is within the range of living indigenous Australians indicates that the lineages of the alleles contributing to this gracile phenotype have survived
Conclusion from link above)
Our analysis has shown that anatomical features and the mtDNA of particular individuals may have different evolutionary paths, and some nuclear gene lineages have genealogical andyor geographical patterns that are different from those of mtDNA (8–10, 14). This difference limits the use of ancientDNAin tracing human evolutionary history because, in most cases, only mtDNA can be isolated and analyzed from ancient material. A fuller understanding of the genetic basis of recent human evolution will require more extensive investigation of nuclear genome variation.

SC: And there is nothing in the science of evolution that would have precluded such from occurring elsewhere on the planet (in a simillar but not identical environment) thereby producing (in parallel) different types of plant - the differences being attributed to the different local environments? We're agreed on this?
SC: Three things.
1) We are always being told that the fossil record is incomplete.
2) How do we know we are not already looking at (some of) the precursor species of a parallel evolution in the extant fossil record?
Has anyone actually looked at the fossil record through the lens of "polyphylogenetic evolution"
Is it not the case that certain fossils do not easily fit into the linear, singular model of evolution
i.e. there are some fossils that have apparently been found in the "wrong" strata?
3) Cremo & Thomson's Forbidden Archaeology cites numerous examples of "anomalous" skulls/skeletons and other anomarts (anomalous artefacts) some of which are apparently millions of years old. I can accept that some of these finds are probable hoaxes or have perhaps been misinterpreted.
I think, however, that it is stretching credibility somewhat to consider that all the evidence they present in FA is the result of a hoax or a misinterpretation of the data. There's just too much of it.

Byrd …So, yes (heavens above) as we've both been saying for the past umpteen pages, we both believe in evolution. You started out, however, with multiple proto lifeforms and I think you've now seen that only one parent stock originated life on earth (whatever the thing was.)
The growing thought, (Byrd can correct me here!) seems to be that we left Africa earlier and had spread into Europe and Asia. The out of Africa model is, therefore, still the accepted model, but with increasing sophistication. Instead of one migration descended from the 'Eves', it allows for several populations that predated Eves, but where related.
Taking this into account, it makes it increasingly reasonable for humans being in position to cross into Americas at the earlier date

However, I still refer to the breaking of the 12.5kya paradigm for the peopling of the Americas to offer hope that the orthodoxy is not unassailable, but that it maintains very high standards of proof.
That's why it's called science...

Thanks Daddybare for posting this topic!!
I must admit, this has been a hell of a debate and a sociable debate without any name calling, flame baiting stuff.
