Article Synopsis
- The study investigates how hybridization and genetic introgression are affected by variations in evolutionary rates across different species and genes, which can lead to inaccuracies in commonly used detection methods.
- It evaluates the performance of three popular tests (D test, D3 test, and HyDe), revealing that they often produce false positives when species lineages have differing substitution rates.
- The findings suggest that relying on these tests without accounting for rate variation can mislead researchers about the prevalence of hybridization, emphasizing the need for alternative methods that do not assume consistent evolutionary rates.
Article Synopsis
- The centropogonid clade, part of the Lobelioideae family, has undergone rapid evolution in the Andes, resulting in complex relationships among species, especially with capsular fruits and flower traits that have evolved similarly across different lineages.
- Targeted sequence capture techniques helped in gathering genetic data from both fresh and preserved plant samples, leading to an improved understanding of species relationships through various phylogenomic analyses.
- Though the study enhances the clarity of phylogenetic ties, significant discrepancies among gene trees and challenges in reclassifying non-monophyletic genera remain due to ongoing morphological innovation and genetic complexity.
