Ever since Darwin there has been a history of debate on the tempo and mode of evolution. Is speciation a gradual process involving the accumulation of minute variations extant within a species, or is it rapid, the result of major organismal reorganization? Does one define a species on the basis of genes, morphology, or geographic or reproductive isolation? In this communication I present a model of evolutionary change that is based on the Mendelian inheritance of mutations in regulatory genes… 
Systematics and Evolution
TLDR
This chapter will be made to summarize the main aspects of these fields of inquiry, including their assumptions, and to suggest avenues of future inquiry that might bring these disciplines together to provide some better information about evolution.
Homeosis of the angiosperm fl ower : Studies on three candidate cases of saltational evolution 1
Gradualism, as outlined in DARWIN’s infl uential book on the origin of species, maintains that evolution proceeds only by infi nitesimally small inherited modifi cations. There is quite some evidence

Abstract The tenets underlying the use of mtDNA in phylogenetic and systematic analyses are strict maternal inheritance, clonality, homoplasmy, and difference due to mutation: that is, there are
Genetics and the making of Homo sapiens
TLDR
The magnitude and rate of morphological evolution in hominids suggests that many independent and incremental developmental changes have occurred that are expected to be polygenic and regulatory in nature.
Gene family evolution and homology: genomics meets phylogenetics.
TLDR
It is shown how the phylogenetic approach makes possible novel kinds of comparative analysis, including detection of domain shuffling and lateral gene transfer, reconstruction of the evolutionary diversification of gene families, tracing of evolutionary change in protein function at the amino acid level, and prediction of structure-function relationships.
Genomics Meets Phylogenetics
■ Abstract With the advent of high-throughput DNA sequencing and wholegenome analysis, it has become clear that the coding portions of the genome are organized hierarchically in gene families and
Sudden origins: a general mechanism of evolution based on stress protein concentration and rapid environmental change.
TLDR
Extreme spikes in environmental stress make possible the emergence of new genetic and consequent developmental and epigenetic networks, and thus also the emerged of potentially new morphological traits, without invoking geographic or other isolating mechanisms.
Allosaurus, crocodiles, and birds: Evolutionary clues from spiral computed tomography of an endocast
  • S. Rogers

TLDR
The ability to directly examine the neuroanatomy of an extinct dinosaur, whose modern‐day relatives are birds and crocodiles, has exciting implications about Allosaurus' behavior, its adaptive responses to its environment, and its eventual extinction.
The evolution of the black wildebeest, Connochaetes gnou, and modern largemammal faunas in central Southern Africa
This study investigates the evolution of modern mammalian faunas in the central interior of southern Africa by testing the hypothesis that the evolution of the black wildebeest, Connochaetes gnou,
A New Model for the Origin of Bipedality
TLDR
The chromosomal location of HOX D is examined and the likelihood that the fusion of two panid chromosomes could have given rise to alterations in its control resulting in the abrupt appearance of bipedality and accompanying changes in the limbs and in the chela in which the HOX sequences are reused is examined.

TLDR
Since paleontologists have been successful in recognizing true "biospecies" on criteria which are as valid and complete as those used to differentiate the majority of recent species, a reappraisal of paleontological models of speciation is called for.
A NEO‐DARWINIAN COMMENTARY ON MACROEVOLUTION
The neo-Darwinian synthesis that resulted from the integration of Mendelian genetics into evolutionary theory has dominated evolutionary biology for the last 30 to 40 years, due largely to its
Punctuated equilibria; the tempo and mode of evolution reconsidered
TLDR
It is argued that virtually none of the examples brought forward to refute the model of punctuated equilibria can stand as support for phyletic gradualism; many are so weak and ambiguous that they only reflect the persistent bias for gradualism still deeply embedded in paleontological thought.
Morphology, paleoanthropology, and neanderthals
TLDR
It is clear that the human fossil record reveals a consistent pattern of systematic diversity—a diversity totally unreflected in the conventional minimalist interpretation of that record, and the Neanderthals are conventionally classified simply as a subspecies of the authors' own species Homo sapiens—a classification that robs these extinct relatives of their evolutionary individuality.
A rapidly evolving homeobox at the site of a hybrid sterility gene.
TLDR
The homeodomain is a DNA binding motif that is usually conserved among diverse taxa and has experienced more amino acid substitutions than it did in the preceding 700 million years; during this period, it has also evolved faster than other parts of the protein or even the introns.

TLDR
Molecular evolutionary genetics provides one of several approaches to dissecting the evolution of developmental systems, by allowing us to reconstruct the history of developmental genetic pathways, infer the origin and diversification of developmental gene functions, and assess the relative contributions of various evolutionary forces in shaping regulatory gene evolution.
Radical alterations in the roles of homeobox genes during echinoderm evolution
TLDR
The expression domains in echinoderms of three important developmental regulatory genes ( distal-less, engrailed and orthodenticle ), all of which encode transcription factors that contain a homeodomain are reported, demonstrating the evolutionary lability of regulatory genes that are widely viewed as conservative.
The evolution of the vertebrate Dlx gene family.
TLDR
Five new zebrafish family members are cloned and additional sequence information is provided for two mouse genes to investigate the evolutionary history of Dlx genes, which suggest an initial tandem duplication produced a linked pair of DLx genes after the divergence of chordates and arthropods but prior to the convergence of tunicates and vertebrates.
Mendelian Genes and Rates of Development
TLDR
The genetic research of the last quarter of a century has given remarkable insight into the constitution of the hereditary material, and it is enabled to regard it as mainly or wholly composed of separable units, arranged in definite order and quantitative proportions in a series of groups.
