Professor Craig debated Professor Wolpert at Central Hall, Westminster, Feb. 28, 2007, with John Humphrys in the chair. Professor Wolpert is Professor of Biology as Applied to Medicine at University College, London and is well known for his atheistic beliefs.
Craig is the author of many books, most recently In Quest of the Historical Adam.

Lewis Wolpert (1929–2021) was “one of the giants of twentieth-century developmental biology. His name is most often associated with the “French flag model” and with his pronouncement that “It is not birth, marriage, or death but gastrulation which is truly the most important time in your life,” but he has made contributions to solving many key problems.”
Here are Wolpert’s views on religion, which he offered in greater depth in Six Impossible Things Before Breakfast (1977).
