Diaphoretickes

Diaphoretickes is a proposed major clade of eukaryotes that includes Archaeplastida, the SAR group, and several other lineages. Its exact membership and relationships remain subjects of phylogenetic study.

Eukaryote: An organism whose cells contain a nucleus and other membrane-bound organelles. Diaphoretickes is proposed as a major branch within this domain of life.
Molecular phylogenetics: The study of evolutionary relationships using DNA, RNA, or protein sequences. Diaphoretickes is assessed through comparisons of molecular sequence data.
Eukaryogenesis: The evolutionary process through which the first eukaryotic cells arose. Diaphoretickes represents a proposed branch within the later diversification of eukaryotes.
Eukaryote phylogeny: The reconstruction of evolutionary relationships among eukaryotic organisms. The placement and unity of Diaphoretickes depend on the broader eukaryote tree.
Archaeplastida: A eukaryotic group that includes land plants, red algae, and glaucophyte algae. This major lineage is included in Diaphoretickes.
Phylogenomic analysis: The reconstruction of evolutionary relationships using data from many genes or whole genomes. Large gene datasets are used to test the proposed clade’s membership.
Eukaryote supergroups: Broad groupings used to organize the major lineages of eukaryotic life. Diaphoretickes emerged from efforts to classify eukaryotes into deep evolutionary groups.
Eukaryotic root: The position of the earliest split in the evolutionary tree of eukaryotes. Alternative root placements can change interpretations of the clade’s early history.
SAR supergroup: A eukaryotic grouping of Stramenopiles, Alveolates, and Rhizaria. SAR is another major lineage placed within Diaphoretickes.
Maximum likelihood: A statistical method that selects the evolutionary tree most likely to produce observed data under a model. It is one method used to infer trees containing the proposed group.
