Original sin often refers simply to the current state of humanity, in that all have sinned and fallen short of the glory of God (Romans 3:23). Evolution does not raise questions about our current state of sinfulness. It does, however, raise questions about how and when the first sin occurred, and how this fallen state was transmitted to all people. The sciences of evolution and archaeology can provide some insight into these questions but are not equipped to answer them. These questions are theological, and over the centuries the church has considered many possible answers. Some of these options are consistent with the scientific evidence currently available.
