Hypothesis

Is the current classification of eukaryotic diversity into six supergroups stable and well-supported?

Conclusion

The current classification scheme of eukaryotes into six supergroups is likely premature and unstable.

Supporting Evidence

  • The classification of eukaryotes has changed rapidly, indicating instability.
  • Support for the six supergroups varies tremendously based on molecular analyses.
  • Some supergroups are well supported, while others lack consistent support.
  • Taxonomic sampling is often limited, affecting the robustness of classifications.

Takeaway

Scientists are trying to figure out how to group living things called eukaryotes, like plants and animals, but they keep changing their minds about the best way to do it.

Methodology

The authors evaluated the stability and support for the six supergroup classification based on molecular genealogies and assessed three aspects of each supergroup.

Limitations

The study highlights the instability of supergroup taxonomies and the variable support for groups based on different molecular analyses.
