🧂The placement of halophilic lineages was restored — Methanonatronarchaeia emerged outside Halobacteria, supporting independent origins of halophily

→ The number of biased taxa dropped from 95.1% to just 2.3%
→ Pruning automatically stopped once further trimming risked loss of phylogenetic signal
Discrepancy between observed and expected amino acid frequencies in taxa:

Excited to share our work on WitChi! 🛠️🖥️
We tested it on the GTDB r220 archaeal supermatrix (5,869 taxa & 10,101 cols) removing 55% of sites in <2h.
The phylogeny showed several interesting groupings with overall improved branch support:
