Haptista Explained
Haptista is a proposed group of protists made up of centrohelids and haptophytes. Phylogenomic studies indicate that Haptista, together with Ancoracysta twista, forms a sister clade to the SAR+Telonemia supergroup, but it may also be sister to the Cryptista (+Archaeplastida).[1] [2] [3] It is thus one of the earliest diverging Diaphoretickes.
Taxonomy
