text: Key innovations are fundamental to biological diversification, but their genetic
basis is poorly understood. A recent transition from egg-laying to live-bearing
in marine snails (Littorina spp.) provides the opportunity to study the genetic
architecture of an innovation that has evolved repeatedly across animals. Individuals
do not cluster by reproductive mode in a genome-wide phylogeny, but local genealogical
analysis revealed numerous small genomic regions where all live-bearers carry
the same core haplotype. Candidate regions show evidence for live-bearer–specific
positive selection and are enriched for genes that are differentially expressed
between egg-laying and live-bearing reproductive systems. Ages of selective sweeps
suggest that live-bearer–specific alleles accumulated over more than 200,000 generations.
Our results suggest that new functions evolve through the recruitment of many
alleles rather than in a single evolutionary step.
