- Cells work like this because DNA is under constant attack from mutations.
- Mutations most commonly arise during cell replication. It's fascinating to realize that the "messiness" of DNA isn't a bug, but a feature—a side effect of evolution's raw material supply chain. Mutations, repeats, transposons, and imperfect repairs all contribute to a noisy genomic landscape. But it's exactly this noise that enables biological diversity. No mutations, no variation. No variation, no selection. No selection, no evolution. The genome is not a blueprint—it's a living, adapting scratchpad. Messiness is the canvas on which nature paints diversity. |
