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]
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.
Understanding phylogenies
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. 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.

2024年6月13日 · A clade is a group of taxa within the phylogenetic tree, including a common ancestor and all its descendants (living or dead). Thus, A and B, with its immediate root, form a clade, while C and D, with its root, form another clade.

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.

2020年6月11日 · What is a Clade? A clade consists of an organism and all of its descendants. For example, the shared ancestor of apes and all of that species descendant species would comprise a “clade.” The term “clade” comes from the Greek “klados,” for “branch.” It’s useful to think of a clade as being one “branch” on the tree of life ...
2.1 Reading Trees - Digital Atlas of Ancient Life
A clade (from the Greek klados = branch) is a group that includes an ancestor (node) and all of its descendants (all shallower nodes and terminal taxa that descend from that node) on a phylogenetic tree. If you pick a node on a phylogenetic tree, you can easily draw a circle around the clade that it defines, as in the tree below.

2024年11月26日 · 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 determine ancestor-descendant relationships.
