I'll have to keep looking for an author who can outline molecular biology for the masses, because Ball doesn't illuminate the science behind DNA analysis very well. But his excavation of his family's South Carolina roots is as entertaining as it was in Slaves in the Family. The conclusion, in which he muses on the 21st century reverence for science and compares it to earlier awe of men of the cloth, is an appropriate antidote to the "gee whiz" of the advances since the double helix was identified in 1953.
