On a episode of ID the Future, guest host Eric Anderson speaks with medical engineer Rob Stadler, co-author with molecular biologist Change Laura Tan of the new book Stairway to Life: An Origin of Life Reality Check. Stadler explains that it’s a “reality check” because many of the “stairway steps” that have to be mounted for chemistry to become biology must, very inconveniently, happen all at once.

DNA can’t survive without repair enzymes, for example, but those enzymes are able to exist because they’re coded in DNA. The reality check is needed, says Stadler, because the media eagerly tout every oversold “advance” in origin-of-life research, ignore the mounting difficulties for an unguided origin of life posed by various fresh discoveries, and parrot the question-begging claim that origins scientists must consider only naturalistic explanations.
