branching and pattern
Datasets are tables consisting of molecular, morphological, ethological and / or other characters and a list of operational taxonomic units ( OTUs ) which may be genes, individuals, populations, species, or larger taxa that are presumed to be monophyletic and that are presumed to form, all together, one large clade ; phylogenetic analysis reconstructs the branching pattern within that clade.
Despite the critical role that dendrites play in the computational tendencies of neurons, very little is known about the process by which dendrites orient themselves in vivo and are compelled to create the intricate branching pattern unique to each specific neuronal class.
It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.

It was widely supported in the Edinburgh and London schools of higher anatomy around 1830, notably by Robert Edmond Grant, but was opposed by Karl Ernst von Baer's embryology of divergence in which embryonic parallels only applied to early stages where the embryo took a general form, after which more specialised forms diverged from this shared unity in a branching pattern.
Darwin recognised the importance of embryonic development in the understanding of evolution, and the way in which von Baer's branching pattern matched his own idea of descent with modification:

When the graph is uniformly random except for the degree distribution, these critical vertices are the ones with the highest degree, and have thus been implicated in the spread of disease ( natural and artificial ) in social and communication networks, and in the spread of fads ( both of which are modeled by a percolation or branching process ).
