TLDR
The results show that the cis-regulatory evolution of a single transcription factor can repeatedly drive the convergent evolution of complex color patterns in distantly related species, thus blurring the distinction between convergence and homology.Abstract:
Mimicry—whereby warning signals in different species evolve to look similar—has long served as a paradigm of convergent evolution. Little is known, however, about the genes that underlie the evolution of mimetic phenotypes or to what extent the same or different genes drive such convergence. Here, we characterize one of the major genes responsible for mimetic wing pattern evolution in Heliconius butterflies. Mapping, gene expression, and population genetic work all identify a single gene, optix, that controls extreme red wing pattern variation across multiple species of Heliconius. Our results show that the cis-regulatory evolution of a single transcription factor can repeatedly drive the convergent evolution of complex color patterns in distantly related species, thus blurring the distinction between convergence and homology.read more

TL;DR: It is inferred that closely related Heliconius species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation.

TL;DR: This work shows how cis-regulatory activity can diverge and how studies of cis-Regulatory divergence can address long-standing questions about the genetic mechanisms of phenotypic evolution.

TL;DR: Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.
Journal ArticleDOI
The genetic causes of convergent evolution.
TL;DR: Evidence for parallel and collateral evolution has been found in many taxa, and an emerging hypothesis is that they result from the fact that mutations in some genetic targets minimize pleiotropic effects while simultaneously maximizing adaptation.
Journal ArticleDOI
Adaptive introgression in animals: examples and comparison to new mutation and standing variation as sources of adaptive variation.
TL;DR: The various attributes of these three potential sources of adaptive variation are compared, including balancing selection for multiple alleles for major histocompatibility complex (MHC), S and csd genes, pesticide resistance in mice, black colour in wolves and white colour in coyotes, Neanderthal or Denisovan ancestry in humans, and mimicry genes in Heliconius butterflies are examined.

Convergence and parallelism reconsidered: what have we learned about the genetics of adaptation?

TL;DR: It is argued that the distinction between 'convergent' and 'parallel' evolution is a false dichotomy, at best representing ends of a continuum.

TL;DR: The genetic basis of evolution may be predictable to some extent, and further understanding of this predictability requires incorporation of the specific functions and characteristics of genes into evolutionary theory.

TL;DR: It is shown that a male wing pigmentation pattern involved in courtship display has been gained and lost multiple times in a Drosophila clade, demonstrating how the functional diversification of the modular CREs of pleiotropic genes contributes to evolutionary novelty and the independent evolution of morphological similarities.

The developmental genetics of homology.
TL;DR: It is proposed that it is the historical continuity of gene regulatory networks rather than the expression of individual homologous genes that underlies the homology of morphological characters.

Genetics and the Evolution of Muellerian Mimicry in Heliconius Butterflies
TL;DR: By hybridizing races of Heliconius melpomene and races of H. erato, it is shown that, as expected from the two-step theory, the races differ at a number of genetic loci, usually unlinked or loosely linked, including at least one mutant of major effect in each case.
