Like the whole Bible, Genesis is history but not scientific history. This does not mean that it is myth or fable, but that its style is often poetic and that its content is selective. The author is like a photographer who points his camera only at the subjects that are important for his purposes, from his point of view. The purpose of the Divine Author of vthe Bible, the Holy Spirit, is to tell us about God and His acts of “Salvation History”.
Did God use evolution? He may have. Genesis is not a science text, so it does not tell us how so much as why. But there are hints. Only three times in the creation account is “bara” used: for the creation of matter (I:I), life (I:2I) and humanity (I:27). The other times, God said, “let the waters bring forth…” or “let the earth bring forth…” that is, for most of His acts of “creation”, He made rather than created.
For example, He used the pre-existing material of “the dust of the earth to make man. Was that an ape body? Perhaps. Why not? Our 'image of God” distinctiveness, our personality, is grounded in the soul, not in the body. We are “rational animals”. God is not an animal.
Catholics have seldom had the difficulties and embarrassments many Protestants have had about creation vs. evolution. Ever since Augustine they have interpreted Genesis’ “days” non literally. (The Hebrew word there, yom, is often used non-quantitatively in Scripture.) Purposes not clocks, measure God’s time.
