The GMYC method models speciation (among-species branching events) via a pure birth process and within-species branching events as neutral coalescent processes.
Like other tracheal branching events, invasion requires the Branchless FGF pathway.
However, models have been limited by a lack of information on the normal sequence and pattern of branching events.
The sequences could then be used to reconstruct not only the sequence of branching events of a phylogeny but also the time when the various events occurred.
In actuality, there have been hundreds of thousands, if not millions, of branching events along that lineage.
The only difference is the number of branching events that occurred within the lineages, whereas the relatedness of the lineages themselves is not affected by this.
In an interesting sideline, Dagg suggests that borrowing processes may in some cases actually contribute to reconfigured designs and thus lead to branching events.
However, unlike their scheme, trees that have labels on branches or nodes other than characters or to define branching events were included, since in many cases these labels refer to classification categories that also reflect shared characteristics (e.g., amniotes).
The GMYC model combines equations that describe species branching events (macroevolution) and within-population coalescent branching (microevolution) on an ultrametric phylogenetic tree.
In other words, we let the stochastic replacement of symbols in a string correspond to branching events in the recruitment process of RDS (Figure 1).
Branch order follows the Reverse Strahler order system [35], by which branches are ranked based on the hierarchical number of branching events starting from the original, primary branch [36].
