Phylogenomics of rapid speciation and adaptation in Andean-Amazonian plant species.

The Andean-Amazonian region presents an abundance of challenging systems to study biodiversity. The wild tomato clade (Solanum sect. Lycopersicon) includes 13 species that rapidly diversified in less that 2.5 million years in phenotype, habitat, and reproductive mode. Using clade-wide whole transcriptome data from this group, we identified a complex mix of forces--including introgression, rapid lineage-specific adaptation, and environmental selection on ancestral variation--that produced this rapid diversification. Using these approaches, I plan to continue investigations of rapid speciation and adaptation processes in other key Andean-Amazonian plant groups to not only understand their individual evolutionary histories, but also to build a comprehensive framework of the climatological and environmental history of this dynamic multi-ecosystem.
