Dr. Bonnette makes an important distinction when it comes to the past.
"These genetic studies, based on many assumptions and use of computer
models, do not tell us how the origin of the human race actually took
place. But, they do show (1) that methodological limitations and radical
contingency are inherent in such studies, which are employed to make
retroactive judgments about deeply ancient populations that can never be
subject to direct observation, and (2) that present scientific claims
against the possibility of a literal Adam and Eve are not definitive (Gauger 2012, 105-122)."
and that human reasoning is the weak link when evaluating data.
"Since the same God is author both of human reason and of authentic
revelation, legitimate natural science, properly conducted, will never
contradict Catholic doctrine, properly understood. Catholic doctrine
still maintains that a literal Adam and Eve must have existed, a primal
couple who committed that personal original sin, which occasioned the
need for, and the divine promise of, the coming of the Redeemer, Jesus
