Published: March 2020

In systems with early stage sex-chromosome evolution, climate gradients can largely explain changes in the sex-determining systems (i.e., genetic or environmental factors). However, in the common frog Rana temporaria, Phillips et al. found that phylogeography, rather than elevation (used as a proxy for climate), was associated with homomorphic sex-chromosome differentiation levels.
