If you were to compare DNA across diverse species, what pattern would you expect to see? The Bio-Origins project at ICR has narrowed its focus to DNA to answer several major creation biology questions. We want to: 1) identify the created kind boundaries;1 2) identify the mechanism by which the kinds underwent diversification into the vast array of species we see today;2 and 3) identify the biological reason why the diversification process is limited to change within kinds.3 We also want to gather evidence against the faulty evolutionary paradigm epitomized by the “tree of life.”4
How would you attempt to answer these questions using DNA as a tool? Would you expect to find a “signature” in DNA that marks which species belong to which kinds? Would you expect to find discontinuity that depicts every species as isolated and unique from every other species?5 Perhaps a signature that genetic change started recently (in the past few thousand years)?
As we hypothesize answers to these questions and try to test them, it is helpful to take stock of what we know about species’ origins. First, we know that species undergo change—you don’t look exactly like your parents. Second, we know how fast (at present) change occurs. For example, we know, on average, how many mutations occur each generation in humans. Third, we know from Scripture that change has happened for only 6,000-10,000 years, not for millions of years (as evolution posits). Fourth, we know that species have descended from the kinds that God created during the creation week.
This knowledge creates a framework in which we can identify underlying assumptions about DNA change that must be addressed before our bigger questions can be answered. Several unknowns are apparent….
