Here’s a really devilish problem to pose to your favorite friend, teacher, or relative who’s a Darwinist true believer. As Your Designed Body co-author Steve Laufmann observes, the relationship between an embryo and its mother is a relationship between unequals. The embryo’s systems are not yet complete so it depends on its mother for its life. This entails communication between the entities. 

But as Laufmann asks, how could such a thing as pregnancy evolve gradually, without guidance or foresight, “when you have to have it in order to have a next generation. Nobody has ever addressed a problem like that.” No, they haven’t, at least not persuasively, which is why Laufmann calls it the “mother of all chicken-and-egg problems.” Darwinian evolution has many of those, as it takes an engineer like Steve Laufmann, or a physician like his co-author Howard Glicksman, to fully recognize. Evolutionary biologists tend to silently glide over such issues, which clearly point to intelligent design. Either that, or they are satisfied by vague speculations. Watch:
