Convergent evolution, the independent acquisition of similar traits in multiple lineages in response to the same selective pressures, is ubiquitous, facilitating adaptation and diversification across the tree of life. Therefore, understanding the genetic mechanisms by which convergence occurs is critical if we are to understand the adaptations that already exist, and the predictability of evolution. We propose to study mimetic convergence across the Lepidoptera using high-throughput sequencing technologies coupled with gene expression analyses to address a major question in this field: the contributions of different genetic mechanisms to convergence across a evolutionary timescale. This will be the first genetic analysis of convergence for a single comparable phenotype evolving under the same selective force across 2-110 million years of evolution.
