The question of the "historical Adam" is a flashpoint for many evangelical readers and churches. Science-and-theology scholar Loren Haarsma—who has studied, written, and spoken on science and faith for decades—shows it is possible both to affirm what science tells us about human evolution and to maintain belief in the doctrine of original sin. Haarsma argues that there are several possible ways of harmonizing evolution and original sin, taking seriously both Scripture and science. He presents a range of approaches without privileging one over the others, examining the strengths and challenges of each.
