Color patterns as a model for connecting developmental mechanisms to phenotypic evolution.

Color patterns in vertebrates reveal key developmental principles that drive phenotypic diversity, with self-organization and instruction guiding pattern evolution.

• Why it matters: Understanding how developmental mechanisms produce diverse color patterns is crucial for unraveling the broader processes of phenotypic evolution and adaptation in vertebrates.
• What they did: The study develops a conceptual framework linking pattern development to diversification, integrating advances in developmental biology, pattern quantification, and phylogenetics across multiple species.
• The result: This framework enhances our ability to connect developmental processes with evolutionary outcomes, offering a roadmap to explore how color pattern diversity arises and evolves across taxa.
