Here, Species A is the outgroup, and Species B, C, and D form the ingroup. In cladistics or phylogenetics, an outgroup[1] is a more distantly related group of organisms that serves as a …

Aug 25, 2025 · An outgroup in a cladogram is a species or group of organisms closely related to the main group under study, known as the ingroup. It branched off earlier in evolutionary history than the …

An appropriate outgroup is typically closely related to the ingroup but not a member of it, ensuring relevant comparisons can be made. The selection of outgroups is crucial; inappropriate choices can …

Nov 12, 2024 · In biology, an outgroup is a group of organisms that is external to a specific clade, population, or species, and is often used as a reference point for understanding the evolutionary …

Dec 12, 2024 · In phylogenetic trees, an outgroup refers to a taxon that is external to the ingroup, the group of taxa being studied. Outgroups serve as a reference point for inferring evolutionary …

Outgroup: Outgroup refers to a group of individuals toward which members of an ingroup harbor a sense of opposition, resistance, and even hatred. Outgroups are required for ingroups to exist.

People often treat others differently based on whether they are members of their ingroup or outgroup, a phenomenon referred to as the intergroup bias (or the ingroup-outgroup bias).

The outgroup is considered a part of the cladistics that provides the relationship between the distantly related organisms. This information specifically will act as the reference group for identifying the …

In cladistics or phylogenetics, an outgroup[1] is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of …

A species or higher monophyletic taxon that is examined in the course of a phylogenetic study to determine which of two homologous character states may be inferred to be apomorphic. The most …
