Genetic structure of prey populations underlies the geographic mosaic of arms race coevolution
M. Hague, A. Stokes, C. Feldman, E. Brodie, E. Brodie
The paper examines coevolution between toxic newts and garter snakes, finding that toxin levels in newts are shaped by neutral population divergence rather than reciprocal adaptation, while snake resistance is driven by local toxin levels.
