Clade - Wikipedia
In biological phylogenetics, a clade (from Ancient Greek κλάδος (kládos) 'branch'), also known as a monophyletic group or natural group, [1] is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. [2]
Taxonomic rank - Wikipedia
Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank.

A clade is a monophyletic taxon or monophyletic group if you prefer. A monophyletic taxon (or a clade) is defined as a taxon that contains only all descendants of a common ancestor and the common ancestor.
Understanding phylogenies
Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade. Clades are nested within one another — they form a nested hierarchy.
ELI5: What is a clade and how does it differ from a class?
A clade is a group of all the animals that share a common ancestor. Mammals are a clade, because all mammals come from a common ancestor to the exclusion of non-mammals. Reptiles are not a clade, because even though they also have a common ancestor, they share it with birds, who are not reptiles.
Clades within clades - Understanding Evolution
A clade (also known as a monophyletic group) is a group of organisms that includes a single ancestor and all of its descendents. Clades represent unbroken lines of evolutionary descent. It’s easy to identify a clade using a phylogenetic tree.

2020年6月11日 · Clades are used to help scientists understand similarities and differences between life forms, and how life changes and develops over time. The idea of classifying organisms based on their relatedness originated with Darwin’s theory of evolution.

A clade is a synchronic, monophyletic set of lineage representatives, where monophyly is defined synchronically as "all and only descendants of a common ancestor" (represented by A'...
5.12: Phylogenetic Classification - Biology LibreTexts
One way of classifying organisms that shows phylogeny is by using the clade. A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to …

2019年6月23日 · Cladistics vs. Evolutionary Taxonomy The important difference between these two theories of taxonomy is that traditional evolutionary taxonomy sometimes accepts paraphyletic clades, while cladistics does not.
