Article Synopsis
- Sexually selected traits, like lizard male dewlaps, may become more important in environments where the breeding season is limited, which impacts their courtship behavior.
- A study tested the connection between dewlap size and seasonal breeding in 44 Mexican lizard species but found that while a relationship existed initially, it disappeared once evolutionary relationships (phylogeny) were considered.
- The findings suggest that seasonality does not strongly drive the evolution of dewlap size, highlighting the complexity of understanding how multiple selection pressures influence trait development.
