I think it is a major problem for Catholic theology.  In a former life when I was known as Jesuitical, I expounded upon this.  Since evolution dismisses the Fall as historical, and DNA tracing of the human genes verifies that there was NO first couple, there are derivatives to this;  no Original Sin, no need for the Immaculate Conception or Baptism, or redemption due to the Fall.  The church knows this but knows not what to do about it.  It has already ceded that the Bible is metaphor/allegory, but is unable to dismiss a major tenet of its faith, and all the negativity of unworthiness cascading from Original Sin...whew.
