The raw pseudoscience fakes claim that humans are "tropical apes who have not adapted to cold climates". However,you should know that the raw pseudscience fakes don't bother to read the scientific literature. If they did, they would know about 2 papers on mtDNA published last year on the topic of human genetic adaptation to cold climates. In today's issue of "Science" magazine there is yet another article on the topic: "Effects of Purifying and Adaptive Selection on Regional Variation in Human mtDNA" Eduardo Ruiz-Pesini, Dan Mishmar, Martin Brandon, Vincent Procaccio Douglas C. Wallace Science Jan 9 2004: 223-226 Abstract A phylogenetic analysis of 1125 global human mitochondrial DNA (mtDNA) sequences permitted positioning of all nucleotide substitutions according to their order of occurrence. The relative frequency and amino acid conservation of internal branch replacement mutations was found to increase from tropical Africa to temperate Europe and arctic northeastern Siberia. Particularly highly conserved amino acid substitutions were found at the roots of multiple mtDNA lineages from higher latitudes. These same lineages correlate with increased propensity for energy deficiency diseases as well as longevity. Thus, specific mtDNA replacement mutations permitted our ancestors to adapt to more northern climates, and these same variants are influencing our health today. As you can see, yet another false pseudoscience claim bites the dust. Tom Billings
