Relative model selection of evolutionary substitution models can be sensitive to multiple sequence alignment uncertainty

This study shows that relative model selection in phylogenetics can be sensitive to MSA uncertainty, with nucleotide data being more affected than amino-acid data.

Relative evolutionary rates in proteins are largely insensitive to the substitution model

The paper investigates how substitution models affect site-wise relative rates in proteins and finds that rates are robust to model choice.

Viral gain-of-function experiments uncover residues under diversifying selection in nature

The paper identifies two residues in bacteriophage λ that evolved under diversifying selection in nature, supporting host-shift evolution through experimental and genomic analysis.
