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]

As nouns the difference between phylum and clade is that phylum is a rank in the classification of organisms, below kingdom and above class; also called a division, especially in describing plants; a taxon at that rank while clade is a group of animals or other organisms derived from a common ancestor species.

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.

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.

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.

2012年3月26日 · A clade is a branch of the evolutionary tree comprising all the organisms that have evolved from one same common ancestral population. This is a monophylletic group. Taxa and clades are not the same. Taxonomist make groups …

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.

Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species. A clade is a relative concept. How you define a clade depends on which species you are interested in classifying. Small clades can include as few …

2022年9月13日 · A clade (noun) is a group of biological taxa (as species) that includes all descendants of one common ancestor, while a taxon (noun) is a taxonomic category or group, such as a phylum, order, family, genus, or species.
