| Cladogenesis is an evolutionary splitting event in which each
branch and its smaller branches forms a "clade", an evolutionary
mechanism and a process of adaptive evolution that leads to the
development of a greater variety of sister organisms.
Cladogenesis is often contrasted with anagenesis, where gradual
changes in an ancestral species lead to its eventual
"replacement" by a novel form (i.e, there is no "splitting" of
the phylogenetic tree.). |Basic topics in evolutionary
