In this episode of Point of View, host Kerby Anderson sits down with Dr. Thomas Woodward, co‑author of the new book Evidence of Design at the Frontier of Biology. The conversation turns to the hidden layers of the genome that many scientists now recognize as far more intricate than the classic DNA‑RNA‑protein chain.

The Hidden Layers of DNA

Woodward describes the DNA double helix as merely a “filing cabinet” for the cell. The real activity occurs in the epigenetic marks that control whether genes are active or silent. He explains that metal tags—tiny chemical groups attached to specific DNA sites—act like switches, and that there are tens of millions of them, arranged in patterns that would be astronomically unlikely to arise by chance.

A Scrabble Analogy for Epigenetics

To illustrate the precision of this system, Woodward compares it to a Scrabble board. He cites a phrase that uses exactly 47 letters: “Take out the trash and walk the dog before plain Scrabble.” Just as each tile must be in the right place to spell a word, each epigenetic tag must be in the right spot to produce a functional cell. The analogy underscores how a seemingly small number of elements can mirror the complexity of billions of genetic instructions.

Design in the Details

Woodward argues that the depth of cellular organization points to an intelligent designer. He references Psalm 139, noting that the intricate choreography of genes and epigenetic signals reflects a “fearfully and wonderfully made” creature. While he stops short of presenting definitive proof, he invites listeners to consider how modern biology can inform their understanding of creation.
