Today we published a Correction on our 2023 @nature.com paper reporting the heimdallarchaeial ancestry of eukaryotes: www.nature.com/articles/s41...
Corrected paper: www.nature.com/articles/s41...
Importantly, the re-analyses of the corrected dataset are consistent with the original findings.

We must have been super lucky that contamination was all from different lineages to each Njord MAG and yet all from the same clade of unknown Asgard so that Njord form monophyletic groups within Asgards in individual gene trees.
