Taxacom: Cavalier-Smith's recent (final) classification and phylogeny of protists (Dec. 2021)

[Kenneth Kinman]

Hi All,
      This weekend I discovered Cavalier-Smith's very recent paper (December 2021), published 9 months after he died.  It is a wonderful article and a synthesis of many decades of his research on protists.  And I was so glad to see that he gave a formal name ( Opizoa ) to the basal Opisthokonta (which I refer to as archaeopisthokonts).  He also rerooted eukaryotes (on Phylum Malawimonada) and more firmly placed other "orphan" taxa as well.  Chromista is still there, but without Picozoa.
      Therefore, below I am updating my Kingdom Protista classification one more time (now with 23 Phyla, plus the 3 exgroup Kingdoms).

NOTES:

Clades 11-12 form the Alveolata clade.

Clades 10-12 form the Halvaria clade.

Clades 9-12 form the "SAR" clade.

Clades 8-12 form the Harosa (a.k.a. "TSAR") clade.

Clades 7-12 form the Chromista clade.

Clades 6-12 form the Corticata clade (a.k.a. Diaphoretickes).

Clades 5-12 form the "eucorta" clade.

Clades 4-12 form the "photaria" clade.

Clades 3-12 form the "natates" clade.
