Understanding the diversification of phenotypes through time—“descent with modification”—has been the focus of evolutionary biology for 150 years. If, contrary to expectations, similarity evolves in unrelated taxa, researchers are guided to uncover the genetic and developmental mechanisms responsible. Similar phenotypes may be retained from common ancestry (homology), but a phylogenetic context may instead reveal that they are independently derived, due to convergence or parallel evolution, or… 
LOCATING EVOLUTIONARY PRECURSORS ON A PHYLOGENETIC TREE
TLDR
A new stochastic model is developed, which explicitly captures the dependency implied by a precursor and permits estimation of precursor locations, and applies it to the evolution of extrafloral nectaries (EFNs), an ecologically significant trait mediating a widespread mutualism between plants and ants.
Evolutionary Patterns of Ammonoids: Phenotypic Trends, Convergence, and Parallel Evolution
TLDR
Some new methods for the study of ammonoid evolution are exemplified by recent case studies, which suggest that adaptation by means of natural selection is a major cause of homoplastic patterns such as convergence and parallel evolution.
Rampant Homoplasy in Complex Characters: Repetitive Convergent Evolution of Amphibian Feeding Structures
Were the Great Transitions in the history of life unique events in which a lineage of organisms evolved from a primitive to a more derived condition? Or during these transitions did separate but
Detecting molecular basis of phenotypic convergence
TLDR
The approach opens the way to systematic studies of numerous examples of convergent evolution in order to link (convergent) phenotype to genotype.
THE LOCI OF REPEATED EVOLUTION: A CATALOG OF GENETIC HOTSPOTS OF PHENOTYPIC VARIATION
TLDR
A synthesis of 1008 alleles described in the literature that cause phenotypic differences among animals, plants, and yeasts highlights the existence of genetic paths of least resistance leading to viable evolutionary change.
Dissecting the basis of novel trait evolution in a radiation with widespread phylogenetic discordance
TLDR
This analysis provides a generalizable example of how to manage discordance when identifying loci associated with trait evolution in a radiating lineage, and identifies candidate loci that could arise either from multiple lineage-specific substitutions or standing ancestral polymorphisms.
The Molecular Basis of Phenotypic Convergence
TLDR
This work distinguishes between convergence as a phenotypic pattern and parallelism as a shared molecular basis for convergence, and addresses the overarching question: What factors influence when parallel molecular mechanisms will underlie phenotypesic convergence.
Convergent Evolution and the Origin of Complex Phenotypes in the Age of Systems Biology
TLDR
Although examples of convergence are known from many domains of life, green plants in particular have remarkable promise for the study of convergence because they are experimentally tractable, have considerable “-omics” and systems biology resources available, and show convergence in a number of important and complex traits.
Genetic and developmental basis for parallel evolution and its significance for hominoid evolution

TLDR
Repeated phenotypic evolution within African apes is also a distinct possibility, and the availability of complete genomes for each of the hominoid genera makes them another model to explore the genetic basis of repeated evolution.

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.

TLDR
This review compares features classified homologous with the classes of features normally grouped as homoplastic, the latter being convergence, parallelism, reversals, rudiments, vestiges, atavisms, and atavism, with convergence as the only class of homoplasy.
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.
Parallelism as the pattern and process of mesoevolution
TLDR
To focus discussions on the role of parallelism in the evolutionary process, it is necessary to establish the view that parallelism represents a continuum or gray zone between homology and convergence.

THE LOCUS OF EVOLUTION: EVO DEVO AND THE GENETICS OF ADAPTATION
TLDR
There is no theoretical or empirical basis for the evo devo contention that adaptations involving morphology evolve by genetic mechanisms different from those involving physiology and other traits, and substantial data on the genetic basis of adaptation from both genome-wide surveys and single-locus studies are examined.
Genetic changes associated with floral adaptation restrict future evolutionary potential

What appear to be the initial stages of degeneration in the anthyocyanin pigment pathway associated with an adaptive change from blue to red flowers in the morning glory Ipomoea quamoclit are described.

TLDR
Advances in developmental genetics, palaeontology and evolutionary developmental biology have recently shed light on the origins of some of the structures that most intrigued Charles Darwin, including animal eyes, tetrapod limbs and giant beetle horns.
