    Molecular Clocks Are Preset to Evolution by Brian Thomas, M.S.* Evolutionary scientists often use results derived from molecular biology dating methods (based on DNA sequence similarities) to bolster their assumptions that some related organisms may have diverged millions of years ago. But like so many other assumption-laden, naturalistic dating techniques, the data is massaged to fit the paradigm instead of having the model adjusted to fit the observed facts.For example, a recent University of Florida press release stated, “A new University of Florida study based on DNA analysis from living flowering plants shows that the ancestors of most modern trees...
  • Evolution's “Molecular Clock”: Not So Dependable After All?

    DNA mutates, and it's a good thing it does. If it didn't, there could only be one kind of life, not the millions there are today, and species could not adapt to new challenges. This is because mutations in genes—the coding portion of DNA—are the raw material for evolution. However, genes make up a surprisingly small fraction of our DNA. If the genome were a cookbook, its 30,000-odd genetic recipes would be scattered among millions of pages of apparently meaningless nonsense. Mutations affect all DNA, not just the genes, and this provides population geneticists with a veritable toolbox of methods...
