Nucleic Acids, which hold clues to the evolution of various animal and hominid taxa, are comparatively weak molecules from other cellular debris, and thus evolutionary biologists are in essence “time trapped”. Fortunately, DNA and protein fragments do exist in fossil remains beyond what theoretical experimentation do suggest. Sequestering of DNA molecules in humic or Maillard-like complexes likely represents a rich source of DNA molecules from from the past, that have yet to be tapped. These molecules were impossible to acquiredue to the selective nature of Polymerase Chain Reaction (PCR). Read more…
