Biological variety and major evolutionary transitions suggest that the space of possible morphologies may have varied among lineages and through time. However, most models of phylogenetic character evolution assume that the potential state space is finite. Here, I explore what the morphological state space might be like, by analysing trends in homoplasy (repeated derivation of the same character state). Analyses of ten published character matrices are compared against computer simulations with…

Journeys through discrete‐character morphospace: synthesizing phylogeny, tempo, and disparity
TLDR
It is argued that there are clear advantages to considering these three lines of enquiry in a single space: the phylomorphospace, which contains fundamentally different approaches used to generate such spaces, with no direct comparison between them, despite the differing evolutionary histories they imply.
Use and misuse of discrete character data for morphospace and disparity analyses
TLDR
The properties of discrete character spaces are described and common pitfalls discussed, and greater caution is recommended when using discrete character data for morphospace and disparity inferences.
Sampled ancestors and dating in Bayesian phylogenetics
TLDR
A Bayesian Markov chain Monte Carlo framework for inferring sampled ancestor phylogenies is developed, properties of the sampled ancestor tree space are investigated, and Bayesian methods to date phylogenies are reviewed and a computational problem connected to calibration methods is addressed.
Approaches to Macroevolution: 1. General Concepts and Origin of Variation
TLDR
“punctuated equilibrium” and “phyletic gradualism” simply represent two cells in a matrix of evolutionary models of phenotypic change, and the origin of trends and evolutionary novelty are not simply functions of ecological opportunity.
Dynamic biogeographic models and dinosaur origins
ABSTRACT A comprehensive analysis of early dinosaur relationships raised the possibility that the group may have originated in Laurasia (Northern Hemisphere), rather than Gondwana (Southern
Null hypotheses for developmental evolution
TLDR
It is important to challenge assumptions that change is very rare for all developmental traits, especially if this assumption is used to sustain an erroneous view that evolution always optimizes adaptive traits toward increasing complexity.
The male sexual apparatus in the order Scorpiones (Arachnida): a comparative study of functional morphology as a tool to define hypotheses of homology
TLDR
Spermatophore capsular patterns appears to be congruent with a recent phylogeny of the order Scorpiones based on phylogenomic data that placed Bothriuridae outside of Scorpionoidea and Liocheles outside of Hormuridae, in contradicton with earlier phylogenetic reconstructions based on morphology.
Hunting Darwin's Snark: which maps shall we use?
TLDR
The aim in this introduction is to identify eight principal themes that might serve as common ground and to listen out for the sound of rushing subterranean waters that hint at caverns of concealed knowledge.
Fullerene‐like structures of Cretaceous crinoids reveal topologically limited skeletal possibilities
TLDR
Polyhedral calyx graphs are generated for the Late Cretaceous, stemless crinoids Marsupites testudinarius and Uintacrinus socialis revealing structural similarities to carbon fullerene and fulleroid molecules and aiding evolution of a novel adaptive phenotype.
Probable basal allosauroid from the early Middle Jurassic Cañadón Asfalto Formation of Argentina highlights phylogenetic uncertainty in tetanuran theropod dinosaurs
TLDR
One of the oldest known and most complete pre-Late Jurassic tetanuran, the probable allosauroid Asfaltovenator vialidadi gen. et sp.

Exhaustion of morphologic character states among fossil taxa.
  • P. Wagner

    Evolution; international journal of organic evolution
  • 2000
TLDR
The prevalence of the exhaustion pattern among different taxonomic groups implies that worker biases are not to blame and instead implicates biological explanations such as intrinsic constraints or persistent selective trends.
Homoplasy: The Result of Natural Selection, or Evidence of Design Limitations?
  • D. Wake
  • Biology
    The American Naturalist
  • 1991
TLDR
In order to explain how morphologies evolve in lineages, both functionalist and structuralist approaches are necessary, combined in a context in which phylogenetic hypotheses and their tests are continuously pursued.
IN SEARCH OF HOMOPLASTIC TENDENCIES: STATISTICAL INFERENCE OF TOPOLOGICAL PATTERNS IN HOMOPLASY
  • M. Sanderson
  • Biology
    Evolution; international journal of organic evolution
  • 1991
TLDR
The present findings do not provide compelling evidence for the existence of “tendencies” in homoplasy, at least among characters used to reconstruct phylogenies, and should be sought elsewhere, probably among a class of characters defined a priori on a structural or functional basis.
Tempo and mode in evolution: phylogenetic inertia, adaptation and comparative methods
TLDR
The concept of phylogenetic inertia needs to be defined and studied with as much care as ‘adaptation’.
Evolutionary patterns in early tetrapods. II. Differing constraints on available character space among clades
TLDR
This work modify techniques similar to those used by ecologists to infer species richnesses to estimate the number of potentially varying characters given the distributions of changes implied by a model phylogeny, and shows that stem lissamphibians and stem amniotes both had restrictions on some parts of character space but also invaded new character space that had been unavailable to stem tetrapods.
PATTERNS OF VARIATION IN LEVELS OF HOMOPLASY
TLDR
There is no significant difference between plant and animal data sets in the amount of homoplasy when the relationship between consistency index and number of taxa is taken into account, although there are still too few molecular studies to be confident of this result.
Inferring and testing hypotheses of cladistic character dependence by using character compatibility.
TLDR
"tree-free" methods for testing the independence of cladistic characters are developed and corroborate instances of dependent evolution hypothesized by previous workers and also identify novel partitions for caecilian amphibians.
Homoplasy and Developmental Constraint: A Model and an Example from Plants1
TLDR
A simple model relating homoplasy to the rate of character change and the number of evolvable states is outlined, both of which may reflect developmental constraints.
