clade

(noun)

A group of animals or other organisms derived from a common ancestor species.

Examples of clade in the following topics:

  • Verrucomicrobia

    • Study of additional proteins from this proposed superphylum suggests that the Poribacteria may be separate from this clade.
    • The Planctomycetes may be basal to the Chlamydiae-Verrucomicrobia-Lentisphaerae clade.
    • Cavalier-Smith has postulated that the Verrucomicrobia belong in the clade Planctobacteria in the larger clade Gracilicutes. 16S rRNA data corroborate that view.

  • Planctomycetes

    • Cavalier-Smith has postulated that the Planctomycetes are within the clade Planctobacteria in the larger clade Gracilicutes.

  • Chlamydiae

    • Cavalier-Smith has postulated that the Chlamydiae fall into the clade Planctobacteria in the larger clade Gracilicutes.

  • Phylogeny of the Eukarya

    • There is widespread agreement that the Rhizaria belong with the Stramenopiles and the Alveolata, in a clade dubbed the SAR supergroup, so that Rhizara is not one of the main eukaryote groups.
    • The Amoeboza and Opisthokonta are each monophyletic and form a clade, often called the unikonts.

  • Diverse Cell Forms of Methanogens

    • These species do not form a monophyletic group, but are split into three clades.

  • Historical Overview of Eukaryotes

    • Even back to Antiquity the two clades of animals and plants were recognized.

  • Gammaproteobacteria

    • Phylogenetically, in the Enterobacteriales, several peptidoglycan-less insect endosymbionts form a sister clade to the Enterobacteriaceae, but since they are not validly described, this group is not officially a taxon; examples of these species are Sodalis, Buchnera, Wigglesworthia, Baumannia and Blochmannia.

  • Rickettsial Diseases

    • Recent studies reclassify the scrub typhus group as a new genus - Orienta, and suggest that the spotted fever group should be divided into two clades.

  • Deinococcus and Thermus

    • Cavalier-Smith calls this clade Hadobacteria (from Hades, the Greek underworld).

  • Chloroflexus and Relatives

    • The six classes that make up the phylum did not consistently form a well-supported monophyletic clade in phylogenetic trees based on concatenated sequences for large datasets of proteins.
