Accumulation Phylogenies

چکیده
Directed acyclic graphs provide a convenient representation of reticulate evolution in systematic biology. In this paper we formalize and analyse a simple model in which evolved characteristics are passed on to all descendant species. We show that the resulting observed sets of characteristics for the species at the leaves uniquely determine the digraph that described the evolution of the species, under certain restrictions. We also provide a characterisation for when this digraph is actually a tree.

The ecological dynamics of clade diversification and community assembly.
Clades diversify in an ecological context, but most macroevolutionary models do not directly encapsulate ecological mechanisms that influence speciation and extinction. A data set of 245 chordate, arthropod, mollusk, and magnoliophyte phylogenies had a majority of clades that showed rapid lineage accumulation early with a slowing more recently, whereas a small but significant minority showed ac...
متن کاملEstimating the Duration of Speciation from Phylogenies
Speciation is not instantaneous but takes time. The protracted birth-death diversification model incorporates this fact and predicts the often observed slowdown of lineage accumulation toward the present. The mathematical complexity of the protracted speciation model has barred estimation of its parameters until recently a method to compute the likelihood of phylogenetic branching times under t...
متن کاملEvolutionary animation: how do molecular phylogenies compare to Mayr's reconstruction of speciation patterns in the sea?
Ernst Mayr used the geography of closely related species in various stages of increasing divergence to "animate" the process of geographic, or allopatric, speciation. This approach was applied to a wide set of taxa, and a seminal paper by Mayr used it to explore speciation patterns in tropical sea urchins. Since then, taxonomic information in several of these genera has been augmented by detail...
متن کاملExplosive evolutionary radiations: decreasing speciation or increasing extinction through time?
A common pattern in time-calibrated molecular phylogenies is a signal of rapid diversification early in the history of a radiation. Because the net rate of diversification is the difference between speciation and extinction rates, such "explosive-early" diversification could result either from temporally declining speciation rates or from increasing extinction rates through time. Distinguishing...
متن کاملSlowdowns in diversification rates from real phylogenies may not be real.
Studies of diversification patterns often find a slowing in lineage accumulation toward the present. This seemingly pervasive pattern of rate downturns has been taken as evidence for adaptive radiations, density-dependent regulation, and metacommunity species interactions. The significance of rate downturns is evaluated with statistical tests (the gamma statistic and Monte Carlo constant rates ...
