New pre-print on Arctic charr parallel evolution
Parallel evolution by non-parallel routes is a major fascination of mine. Here we have a pre-print submitted (and ms in the appropriate pipelines) about how such parallel evolution can happen, overcoming non-parallel backgrounds. The transcriptome! This is the outcome of a major group effort, including two PhD theses and many many years' worth of sampling ... Preprint at https://www.biorxiv.org/content/early/2018/02/14/265272.article-info Abstract: Quantifying the extent to which evolution is predictable is critical to understanding biodiversity origins and its responses to future environmental challenges 1,2 . Replicate, or parallel, phenotypic evolution has been found in classic examples such as anole lizards, stickleback fishes, salmonid fishes, and cichlid fishes 3-8 and reflects similar adaptive outcomes. However it is not well understood if, how, and at what rate ecologically relevant phenotypic evolution can overcome the heterogeneous genetic backgro...
