Evidence for God, Part 4: Biology Which Evolution Cannot Explain

This week, my Evidence for God series will take a second look at arguments based on the appearance of design, sometimes called teleological arguments, from the Greek word telos, which means “design” or “purpose.” Last week, we looked at how the essential structure of the universe makes life possible through “fine-tuning” which cannot be explained through mere chance. Today, I want to move beyond the possibility of life to consider the actual life forms we see around us. There are two ways in which biology demands a designing intelligence: First, the complexity of biological information contained in even the most basic life form, and second, the “irreducible complexity” of biological structures which cannot be explained through evolutionary processes.

What About Evolution?

When we talk about the appearance of design in biology, we have to start by considering the theory of evolution. Every scientist would agree that living creatures seem to have been uniquely designed for their environments. In fact, the famous evolutionist Richard Dawkins defined biology as “the study of complicated things that appear to have been designed for a purpose.” The key word in that definition, of course, is “appear.” For the last two hundred years, Charles Darwin’s theory of evolution has offered a way to explain the appearance of design without requiring a designer. Evolution postulates that natural processes mold species over time, through adaptation and the pressure to survive, so that animals look like they were designed for their particular ecological niche. In reality, though, this “design” is merely the result of a process of natural selection whereby the best-adapted survive and reproduce while the rest perish, removing their less-fit genes from future generations.

Evidence for God, Part 3: Universal ‘Fine-Tuning’ for Life

Equations

Last Thursday we considered how the sheer fact that the universe exists at all is evidence for the existence of a supernatural creator. Today, as part of my continuing Evidence for God series, I want to move from the existence of the universe to its apparent design; what scientists have described as “fine-tuning.”

Arguments that there must be a God since the world appears to be designed are called teleological arguments, from the Greek word telos, which means design or purpose. Such arguments come in multiple flavors. Next week, I’ll look at evidence for design in the development of life and in biological complexity, but first we need to consider design so large-scale, so integral to the fabric of existence itself, that it is easy to miss. In fact, scientists and theologians alike only stumbled upon this evidence for God within the past century.
