Most common evolutionary dating methods
Polygenism is the proposed vision of almost all evolutionary theorists. As life emerged from one-celled organisms, ultimately more complex forms of life arose to include fish, then reptiles, mammals, higher forms of mammals and early humanoid forms, and then the first .But, presumably this process did not occur only in one case.What Genesis tells us is true, but it speaks to us in a summary sort of way, more as a poetic description than an earth science textbook. As the Catechism states: Scripture presents the work of the Creator symbolically as a succession of six days of divine ‘work,’ concluded by the ‘rest’ of the seventh day” ….”nothing exists that does not owe its existence to God the Creator. We also discussed that Catholics may be open to the scientific teachings of evolution but that they cannot accept it uncritically, without certain distinctions.The world began when God’s word drew it out of nothingness; all existent beings, all of nature, and all human history is rooted in this primordial event, the very genesis by which the world was constituted and time begun” (CCC 337-338). Catholics are free to believe in some sort of evolutionary or gradual process as a secondary cause of biodiversity.Now it is in no way apparent how such an opinion can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all and is in everyone as his own (Humani Generis, 36-37).Hence, it seems clear that a Catholic is not free to accept polygenism.There are some in theological circles who have attempted to assert that the Pope is merely saying it is not apparent how such a theory can be reconciled, but not actually indicating that such a view be rejected.But this seems fanciful since the Pope says quite clearly that Catholics “by no means enjoy such liberty” and “cannot embrace” the opinion of polygenism.
The great interest accorded to these studies is strongly stimulated by a question of another order, which goes beyond the proper domain of the natural sciences.
But this presents a problem for a Catholic who might wish to uncritically accept evolution, for, simply put, we cannot accept polygenism.
Pope Pius XII in 1950 specifically addressed the problem of polygenism in the Encyclical [T]he Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter…..
Hence, this theory, Adam and Eve are merely symbols of Mankind.
Rather than being an historical couple, they represent the human race as it emerges from the hominids that gave rise to them as they become historical figures who actually existed and from them alone the whole of the human race is descended.
