However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Retention of the Full Visual Opsin Repertoire in Some Australian Cryptozoic Lizards
Ecology and Evolution, Volume 16, Issue 6, June 2026.This study investigates the link between visual evolution and fossorial habits in the endemic Australian skink genus Lerista. We provide evidence for positive site‐specific selection in all 4 cone opsins, as well as relaxed selection specific to LWS. We also provide evidence of selection linked to limb reduction, an indicator of fossorial adaptation ...
