Neanderthal DNA sequences and the origin of modern humans
Article Abstract:
A series of DNA specimens that were extracted from the right humerus of aNeandertal-type specimen was analyzed by amino acid racemization and DNA amplification techniques to characterize the its DNA patterns. DNA amplification of the Neanderthal samples indicated the presence of an amplification product that was composed of two classes of sequences. Pairwise amino acid sequence comparisons of the mitochondrial DNA indicated the wide genetic differences between modern humans and neandertals.

Facts and artifacts of ancient DNA
Article Abstract:
Neandertals once characterized as a an ancient race of human beings that wer genetically absorbed into the population of Homo sapiens through cross-breeding. However, genetic analysis of Neandertal mitochondrial DNA indicated the absence of amino acid sequence similarity between modern humans and the ancient species. Mitochondrial DNA analysis from samples collected in Neandertal bones also indicated the absence of similarity between the modern human genome and the Neandertals.

mtDNA analysis of Nile River Valley populations: a genetic corridor or a barrier to migration?
Article Abstract:
Studies reveal a genetic migrational pattern among populations along the Nile River Valley. Using first hypervariable segment sequences of the control region of the mtDNA, coupled with a polymorphic Hpa1 site, researchers were able to determine the migrations to be between a few hundred to a few thousand years old, and predominantly from south to north.
