Analysis reveals intraindividual and intraspecific variation impacts natural selection in two lizard species, suggesting varying selection regimes.

Intraindividual phenotypic variation significantly influences natural selection and its detection in lizards, complicating traditional interpretations.
Capturing traits at different measurement instances revealed that selection inference relied on intraindividual variation, challenging conventional understanding of heritable traits.
Using a long-term capture-mark-recapture study, variation in traits was observed in two lizard species, with differences detected in selection pressures within the same habitat.
The findings highlight that even convergently evolved species can experience different selection pressures based on their ecological context.

Roches et al. (2025) studied this question.
