Biological Fine-Tuning

TNRTB Archive - Retained for reference information

A new design feature in living systems provides more evidence for intelligent design. A biologist noted that metabolic rates are universally fixed (metabolic rate scales as the ¾ power of the mass) across the living spectrum—from individual molecular reactions up to the largest of organisms. This fine-tuning observation demonstrates that a fundamental design principle must underlie the structure, function, and organization of biological systems. In other words, there must be severe constraints on the ways that biological systems can be designed. The lack of design options for life makes naturalistic explanations for life even more unlikely than they already are.

In 1999, I left my position in R&D at a Fortune 500 company to join Reasons to Believe because I felt the most important thing I could do as a scientist is to communicate to skeptics and believers alike the powerful scientific evidence—evidence that is being uncovered day after day—for God’s existence and the reliability of Scripture.
