Kind: research · Impact: low

## In brief

- New research from the University of Bath analyses mutation data to test the idea that important genes mutate less often than others.
- The idea was first proposed in 1972 as a challenge to the traditional view of evolution and has remained contentious.
- The source excerpt indicates the new study finds the evidence behind the theory to be weak or unconvincing.

## Why it matters

The claim that evolution shields essential genes from mutation affects how researchers interpret mutation rates across the genome and the role of selection in shaping gene variation.
