clades, plural;
  1. A group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics

  1. a group of biological taxa or species that share features inherited from a common ancestor
  2. A clade(from Ancient Greek κλάδος, klados, "branch") is a group consisting of an organism and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". ...
  3. Clade is a science fiction novel written by Mark Budz, published in 2003. In Clade, an environmental disaster called the Ecocaust has caused sea levels to rise and causing additional strains on human resources. ...
  4. A group of animals or other organisms derived from a common ancestor species; A higher level grouping of a genetic haplogroup
  5. (Clades) A clade is a term used to distinguish a taxonomic group that consists of a common ancestor and all descendents (cladograms are graphical depictions of these relationships; see Phylogenetic).
  6. (clades) a branching diagram that shows evolutionary relationships of organisms
  7. A group of organisms, such as a species, whose members share homologous features derived from a common ancestor. The avian virus H5N1 clade 1 includes human and bird isolates from Vietnam, Thailand, Cambodia, Laos, and Malaysia. ...
  8. A group comprising all the evolutionary descendants of a common ancestor. In the scientific literature, clades are given letter and number designations, like H, U4 and L3a1. ...
  9. in cladistics, a group with a common set of shared derived characteristics persumed inherited from a common ancestor
  10. A group of organisms that are genetically similar and descended from a single parent organism. With HIV, the term "clade" refers to a group of specific HIV-1 strains within an HIV subtype. For example, HIV-1 subtype M contains clades A through H, J, and K. ...
  11. Branch (Gk.) or lineage which has split off from an ancestral group, as defined by advanced or derived traits.
  12. A clade is a group of biological taxa (as species) that includes all decendents of one common ancestor. Source: Merriam-Webster'sCollegiate Dictionary (11th ed.)
  13. A group of species or genes that includes all descendants of an ancestral species or gene. See monophyletic.
  14. Group of organisms which share a common ancestor and form a phylogenetic lineage. In terms of HIV, the term "clade" is often used to refer to a sub-type.
  15. a monophyletic group, a group of organisms consisting of a common ancestor and all that ancestor's descendants. "Class Reptilia" is not a clade because some reptiles (dinosaurs) evolved into birds (non-reptiles). ...
  16. one of the major, largely geographically isolated, HIV subtypes. Classification is based on differences in ENVELOPE PROTEIN. Clade B makes up the overwhelming majority of HIV in North America and Europe.
  17. A group of biological species that can be traced to/share a single ancestor. A useful taxonomic grouping for the purposes of understanding evolutionary biology.
  18. In biological systematics, a clade is a monophyletic grouping of taxa where all members share a common ancestor; the clade is defined by the presence of one or more derived features shared by the members (synapomorphies).
  19. An evolutionary lineage of organisms that includes the most recent common ancestor of all those organisms and all the descendants of that common ancestor.
  20. Group of organisms defined on the basis of common ancestry as indicated by shared, derived characters (synapomorphies).
  21. the entire portion of a phylogeny that is descended from a single ancestral species and is therefore a monophyletic group.
  22. a monophyletic group.
  23. A clade is a group of all the organisms that share a particular common ancestor (and therefore have similar features). The members of a clade are related to each other. ...
