Common dna sequences: evidence of evolution or efficient design by jeffrey p tomkins, phd | saturday, august 01, 2009 with the advent of modern biotechnology, researchers have been able to determine the actual sequence of the roughly three billion bases of dna (a,t,c,g) that make up the human genome. Organisms and evolution you have already been exposed to the study of living systems at the molecular and cellular levels for the most part, that study emphasized features that are common to all living systems, except perhaps for the important distinction between prokaryotes and eukaryotes. Cladistics is a particular method of hypothesizing relationships among organisms like other methods, it has its own set of assumptions, procedures, and limitations cladistics is now accepted as the best method available for phylogenetic analysis, for it provides an explicit and testable hypothesis of organismal relationships.
