SURPRISES FROM THE FIRST READING OF THE GENOME
Entire books have been written about the Human Genome Project (probably too many, in fact). Perhaps I'll write my own someday, hopefully with sufficient hindsight to avoid some of the breathless pronouncements of many of the currently popular depictions. It is not the purpose of this book, however, to
dwell further upon that remarkable experience, but rather to reflect upon the ways that a modern understanding of science can be harmonized with a belief in God.
