Pulsed evolution shaped modern vertebrate body sizes
The relative importance of different modes of evolution in shaping phenotypic diversity remains a hotly debated question. Fossil data suggest that stasis may be a common mode of evolution, while modern data suggest some lineages experience very fast rates of evolution. One way to reconcile these observations is to imagine that evolution proceeds in pulses, rather than in increments, on geologic...
متن کاملDetecting Macroevolutionary Self-Destruction from Phylogenies.
Phylogenetic analyses have lent support to the concept of lineage selection: that biological lineages can have heritable traits that influence their capacity to persist and diversify, and thereby affect their representation in biodiversity. While many discussions have focused on "positive" lineage selection, where stably heritable properties of lineages enhance their diversification rate, there...
متن کاملGeiger V2.0: an Expanded Suite of Methods for Fitting Macroevolutionary Models to Phylogenetic Trees
SUMMARY Phylogenetic comparative methods are essential for addressing evolutionary hypotheses with interspecific data. The scale and scope of such data have increased dramatically in the past few years. Many existing approaches are either computationally infeasible or inappropriate for data of this size. To address both of these problems, we present geiger v2.0, a complete overhaul of the popul...
متن کاملExample 2: Fitting Latent Class Models Using Add-on Packages
Many scientific computations can be sped up by dividing them into smaller tasks and distributing the computations to multiple systems for simultaneous processing. Such a process is referred to as parallel computing. When performed on existing grids of computers, this method can dramatically increase computation speed. Several solutions exist to facilitate this type of computation within R, and ...
متن کاملUsing Phylogenies to Test Macroevolutionary Hypotheses of Trait Evolution in Cranes (Gruinae).
We present a novel phylogenetic approach to the study of trait evolution. We compare explicit models describing the evolution of phenotypic characters over the phylogeny of a group, employing a method that avoids point estimates of ancestor reconstructions (see Maddison 1990, 1995; Losos and Miles 1994; Schluter et al. 1997; Zhang and Nei 1997; see also Pagel 1997). We contrast well-characteriz...
