Integrative utilization of genomic resources for improved phylogenetic resolution in Sonerileae (Melastomataceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Advances in new next‐generation sequencing (NGS) methods have revolutionized phylogenetics, yet challenges remain in effectively utilizing data from a wide range of sources. A well‐resolved and broadly sampled phylogeny for Sonerileae, the second‐largest tribe in Melastomataceae, is still lacking, hindering our understanding of its ...

If, as Einstein said, "it is the theory which decides what we can observe," then "the species problem" could be solved by simply improving our theoretical definition of what a species is. However, because delimiting species entails predicting the historical fate of evolutionary lineages, species appear to behave according to the Heisenberg Uncertainty ...
