The Search for Selection


6-10 September 2021

A vast number of approaches have been suggested in the search for selection, ranging from genomic‐based signatures of recent or ongoing selection, tests based on either excessive amounts or nonrandom patterns of divergence (in both fossil sequences and with functional genomics data) and the more classical Lande‐Arnold fitness estimates (direct association of phenotypic values with fitness estimates) and their modern extensions. This workshop presents an integrated overview of all these approaches.
