The Sense of Hearing Is a Masterpiece of Engineering

Several different structural components are necessary for the vertebrate sense of hearing. It strains credulity to suppose that an unguided process of random variation sifted by natural selection could assemble such a delicately arranged system. It instead points to a cause with foresight.

The Incredible Design of Muscles

Muscle is one of the most fundamental of animal tissues. It is muscles that animate our bodies — allowing us to move, stand upright, breathe, and even speak. Muscles are precisely the sort of thing that we might expect a designer of embodied intelligent beings to produce.

How NOT to Argue Against Irreducible Complexity

Here, I will address an objection to irreducible complexity I’ve encountered that attempts to handwave the argument away as though I were missing something obvious. This is, in my judgment, one of the weakest objections to irreducible complexity, though it persists as a popular one — even among experts. It is therefore worth commenting on. I will use as case examples two responses to recent articles of mine.

For Males, an Engineering Marvel that Originates in the Brain

As in the case of so many physiological processes, the male erection and ejaculation reflex requires multiple processes to function in unison to achieve a higher-level objective — in this instance, depositing seminal fluid, containing millions of sperm cells, in the female vaginal cavity.

New Article in Science Boosts Plausibility of a Primordial Pair

Though there is no direct evidence for Adam and Eve having existed, this does not necessarily make the belief irrational. In principle, it may be supported by indirect evidence (if one holds to a religious belief, itself well supported by evidence, that implies the historicity of Adam and Eve). Either way, current science tells us little about whether Adam and Eve plausibly existed.

The Incredible Design of Vertebrate Blood Clotting

The intricacies of vertebrate blood clotting represent a significant challenge to evolutionary mechanisms. The process of clot formation is itself irreducibly complex and must also emerge simultaneously with a mechanism to prevent excessive clotting and to confine the clot to the site of injury. From a neo-Darwinian perspective, it is difficult to envision such a system emerging one step at a time without passing through maladaptive intermediate stages.

The Genius of the Fetal Circulatory System

It is difficult to imagine a more profound testimony to design than the delivery of a fully developed baby that, only nine months ago, was a single cell. Few biological phenomena are as gripping and awe-inspiring as the process of reproduction and the development of a baby in utero. The signature of design here is unmistakable, for so much of the process — from conception to delivery — depends on foresight and planning.
