Clade

A clade (from κλάδος, klados, "branch"), also known as monophyletic group, is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life".

Cladistics

Cladistics (from Greek κλάδος, cládos, i.e., "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.

Convergent evolution is the independent evolution of similar features in species of different lineages.

Crown group

In phylogenetics, the crown group of a collection of species consists of the living representatives of the collection together with their ancestors back to their most recent common ancestor as well as all of that ancestor's descendants.

Hybrid speciation

Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species.

Paraphyly

In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups.

Phylogenetic tree

A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics.

Polyphyly

A polyphyletic group is a set of organisms, or other evolving elements, that have been grouped together but do not share an immediate common ancestor.

Symplesiomorphy

In phylogenetics, a plesiomorphy, symplesiomorphy or symplesiomorphic character is an ancestral character or trait state shared by two or more taxa.

Synapomorphy and apomorphy

In phylogenetics, apomorphy and synapomorphy refer to derived characters of a clade – characters or traits that are derived from ancestral characters over evolutionary history.
