Parallel evolution

The paths of parallel evolution and their genetic crossroads (2011-2015). Financed by the Portuguese Science Foundation – FCT (PTDC/BIA-EVF/113805/2009), Portugal.

Summary
This project seeks to clarify the nature of the genetic variation responsible for parallel evolution and ecological speciation.The principal investigator (PI) has established an international collaboration to study the genetic basis of parallel speciation in L. fabalis. Benefiting from the experience of well established research groups studying ecological speciation in littorinid species, the scientific merit and innovative nature of this project from an international standpoint offers a good opportunity for Portuguese institutions and scientists to occupy an important niche within European science. The project will employ an innovative sampling design and a multidisciplinary approach focusing on ecology, morphology, genomics, transcriptomics and modelling, with the aim of identifying and characterizing loci under disruptive selection among ecotypes in different geographic regions. This will allow us to shed light on the genetic mechanisms of ecotype evolution and more specifically, to understand if parallel divergent evolution evolves through the same genetic paths. In other words, how repeatable is ecotype evolution?

PI: Rui Faria
