The past decade has seen a remarkable revision of perspectives on unisexual reproduction
in vertebrates. One can no longer view it as a rare curiosity far outside the mainstream of …

The remarkably rapid growth of molecular genetics during the past two decades and
concomitant advances in DNA technology have had an enormous impact in systematic and …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

Concerted evolution is the production and maintenance of homogeneity within repeated
families of DNA. Two mechanisms—unequal crossing over and biased gene conversion …

The cellular and molecular mechanisms governing sexual reproduction are conserved
across eukaryotes. Nevertheless, hybridization can disrupt these mechanisms, leading to …

Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1%
reproduce via asexual or clonal means, which vary wildly and are fascinating in their own …

Publisher Summary This chapter provides an outline of the methods used for classifying and
identifying polyploid animals, followed by a discussion of proposed explanations for its …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Understanding the source and diversity of clones is necessary to resolve the complicated
issues surrounding the apparent evolutionary stability of sexual reproduction. The source of …

A synopsis is provided of different expressions of whole-animal vertebrate clonality (asexual
organismal-level reproduction), both in the laboratory and in nature. For vertebrate taxa …
