Your genome? Which one?

      Gluadys: This article makes two false accusations. (1) That [the genes
      in cells downstream don*t get modified] was just assumed. No, that was not
      assumed. It has long been known that mutations occur in every cell
      replication. (2) The prevailing wisdom has been that every cell in the
      body contains identical DNA. Incorrect. The correct statement would be
      that every cell in the body contains the same genome. Most cells contain
      two copies of the genome of the organism. However, because of both DNA
      mutations and sometimes chromosomal changes occurring every time a cell
      replicates, the details of the genome may differ from cell to cell. So
      although it is still the same genome in every cell, it is not precisely the
      same DNA. Confusion of this sort comes about because people don't
      distinguish properly between base nucleotides (the stuff of DNA), genes and
      genomes, and cells. What changes are the base nucleotides, not the genes or
      genomes. Changes in base nucleotides produce different versions of a gene
      (alleles), but not different genes. So the set of genes (genome) is the
      same. So, in short, this startling "news" is old hat and has nothing to do
      with naive assumptions or unchallenged prevailing wisdom.

      Charles P: After you have read Shapiro*s book, you might agree that what
      the study shows is empirical and verifiable evidence consistent with
      natural genetic engineering.

      Gluadys: Here is a site I found helpful in explaining the origin of
      somatic mosaicism.

      Charles P: Shapiro has seven references to mosaic and mosaicism in his
      book, *Evolution: A View From The 21st Century.

      James A Shapiro: The conventional approach has been to circle the wagons
      around mid-19th and mid-20th century ideas (Darwinism and neo-Darwinism).
      This approach has not been successful. One reason Darwinism has failed to
      convince skeptics may be that it ignores over 60 years of molecular science.
