Un justo reconocimiento al excelente trabajo y la destacada contribución del grupo de trabajo y colegas del Dr. Riccardo Papa quienes con su esfuerzo han contribuido al conocimiento a través de la publicación de los siguientes dos artículos en las revistas Science Advances y Nature Communications.

Lewis JJ, Van Belleghem SMPapa R, Danko CG, Reed R. Many functionally connected loci foster adaptive diversification along a neotropical hybrid zone. Science Advances  25 Sep 2020: Vol. 6, no. 39, eabb8617. DOI: 10.1126/sciadv.abb8617 https://advances.sciencemag.org/content/6/39/eabb8617/tab-pdf

This publication uses complex computational analyses on a large genomic dataset that includes a diverse set of data (whole genome sequences, chromatin immunoprecipitation, Hi-C and RNA-seq) to identify three-dimensional adaptive hubs of physically interactive genes. This publication represent a very novel concept and approach to identify functional connections between loci under selection that may resolve the disparity between large-effect and polygenic evolutionary models.

Rossi M., Hausmann AE., Thurman TJ, Montgomery SH, Papa R, McMillan WO, Jiggins C, Merrill RM. Visual mate preference evolution during butterfly speciation is linked to neural processing genes. Nat Commun 11, 4763 (2020). https://doi.org/10.1038/s41467-020-18609-z

This work characterizes the connection between visual mate preference and brain neural signaling using a combination of QTL, RNA-seq expression and population genomics approaches. The study provides insight into the genetic mechanisms (genes and gene network) underlying changes in mate preference behaviours that involve modification in visual integration or processing. Overall these findings suggest that mate preference could evolve without altering perception of the wider environment.
