Here lets clarify for the third grader among us. The specific reference above is referring to genetic "evidence" that neanderthal and homo sapien diverge approximately 600,000 years ago. However, there just isn't enough time for the changes required to differentiate N for HS according to Darwin's theory to occur in that relatively short time. So if Loki was the legend in his own mind that he likes to try and convince everyone else of, he would be aware of this facts and he would have know that this was inferred from my statement above. Let's refer back to my un-Loki-polluted statement:
"Furthermore, evolution would ask us to believe that for evolution to occur
[in the time periods claimed], it needs to "work" in small populations. Based on dna evidence, a small band of Neanderthals would have to have separated from the group and then lived in total isolation for 600,000 years."
And Loki's typical response??? Just yell Strawman and maybe no one will notice what an incompetent moron you are. Please Loki, explain this strawman...
"Evidence from sequencing mitochondrial DNA indicated that no significant gene flow occurred between H. neanderthalensis and H. sapiens, and, therefore, the two were separate species that shared a common ancestor
about 660,000 years ago.[95][96][97] However, the 2010 sequencing of the Neanderthal genome indicated that Neanderthals did indeed interbreed with anatomically modern humans circa 45,000 to 80,000 years ago (at the approximate time that modern humans migrated out from Africa, but before they dispersed into Europe, Asia and elsewhere).[98] Nearly all modern non-African humans have 1% to 4% of their DNA derived from Neanderthal DNA,[98] and this finding is consistent with recent studies indicating that the divergence of some human alleles dates to one Ma, although the interpretation of these studies has been questioned."
"Current research has established that humans are genetically highly homogenous; that is, the DNA of individuals is more alike than usual for most species, which may have resulted from their relatively recent evolution or the possibility of a
population bottleneck resulting from cataclysmic natural events such as the Toba catastrophe.[112][113][114]
Distinctive genetic characteristics have arisen, however, primarily as the result of small groups of people moving into new environmental circumstances. These adapted traits are a very small component of the Homo sapiens genome, but include various characteristics such as skin color and nose form, in addition to internal characteristics such as the ability to breathe more efficiently at high altitudes."
Speciation events are important in the theory of punctuated equilibrium, which accounts for the pattern in the fossil record of short "bursts" of evolution interspersed with relatively long periods of stasis, where species remain relatively unchanged.[231] In this theory, speciation and rapid evolution are linked, with natural selection and genetic drift acting most strongly on organisms undergoing speciation in novel habitats or
small populations. As a result, the periods of stasis in the fossil record correspond to the parental population and the organisms undergoing speciation and
rapid evolution are found in small populations or geographically restricted habitats and therefore rarely being preserved as fossils.
Allopatric speciation suggests that
species with large central populations are stabilized by their large volume and the process gene flow. New and even beneficial mutations are diluted by the population's large size and are unable to reach fixation, due to such factors as constantly changing environments.[15] If this is the case, then the transformation of whole lineages should be rare, as the fossil record indicates.
Smaller populations on the other hand, which are isolated from the parental stock, are decoupled from the homogenizing effects of gene flow. In addition, pressure from natural selection is especially intense, as peripheral isolated populations exist at the outer edges of ecological tolerance.
