This universal evolutionary perspective leads many Catholics and others to conclude that a literal Adam and Eve is “scientifically impossible” for two reasons: First, paleoanthropologists deny the sudden appearance of intelligent, self-reflective, fully-human primates, but rather view the emergence of consciousness and intelligence as taking place slowly and incrementally over long periods of time.Second, in light of recent findings in molecular biology, especially from studies based on genetic data gleaned from the Human Genome Project, it is claimed that the hominin population (the primate group from which modern man is said to have arisen) has never had a bottleneck (reduced population) of a single mating pair in the last seven or more million years: no literal Adam and Eve.By calling the story a “myth,” people avoid saying it is mere “fantasy,” that is, with no foundation in reality at all.While rejecting a literal first pair of human parents for all mankind, they hope to retain some “deeper” truth about an original “sinful human condition,” a “mythic” meaning.Over time, these “pre-split” lineages, themselves, evolved into the new additional versions present today.Because each individual carries only two versions of a gene, a single founding pair could not have passed on the thirty-two versions that Ayala claimed existed some seven million years ago—either at that time or at any time since.Paleoanthropological claims of gradual appearance of specifically human traits fail to comport with a true philosophy of human nature. Thomas Aquinas demonstrates that true man is distinguished essentially from lower animals by possession of an intellectual and immortal soul, which possesses spiritual powers of understanding, judgment, and reasoning ( I, 75).While these qualitatively superior abilities are manifested through special forms of tool making or culture or art, they need not always be evident in the paleontological record.
Accepting the common ancestor theory, he claimed that there were thirty-two ancient lineages of the HLA-DRB1 gene prior to the split (approximately seven million years ago).
Natural scientific studies employ the inductive method of reasoning.
Empirically observed data is employed to form testable hypotheses.
Molecular biologists use computer models in an attempt to validate such hypotheses and reach conclusions about genetic conditions in early primate populations.
In this process, some researchers have committed the logically invalid move of inferring from particular data to the universally negative claim that a literal Adam and Eve is impossible.
Irrational animals, including subhuman primates, are capable of complex sentient behaviors often approaching or imitating the rational activities of true man.
