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.
