9  Phylogenomics

This is part of the UHH MSc Biology Course EvoSys 2023 (8/11)

Principally phylogenomics = phylogenetics + more data (e.g. whole genome), BUT …

• effort in assembling datasets decreases data quality, use of automatic tools is inevitable
• phylogenomics are more prone to model misspecification, systematic error can amplify and increases along with alignment length
• hidden paralogy, HGT, ILS, hybridization might be buffered in large datasets or negatively affect tree inference
• more data increasing precision (reduction of stochastic errors) but not necessarily the accuracy
