Evolutionary biology

Evolutionary history that is a network, not a tree

In evolutionary biology, reticulation is history that does not fit a branching tree because lineages exchange genes (through hybridisation, horizontal gene transfer, or recombination), so the genealogy forms a network with merging as well as splitting edges. It is represented by phylogenetic networks rather than trees. Huson and Bryant's 2006 Application of phylogenetic networks in evolutionary studies set out the methods for inferring and drawing such networks. The referent is reticulate genealogy among lineages, not a leaf's vein mesh or a radiological texture.[1]

Unit
The amount and placement of network (non-tree-like) signal in a genealogy
Recovery means
Not applicable
Measured by
Inferred from conflicting gene trees and quantified by reticulation events or network summaries such as split graphs
