We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

Parthenogenesis is asexual reproduction without any required participation from males and,
as such, is a null model for sexual reproduction. In a comparative context, we can expand …

DNA sequence indicates the Lacertidae contain two subfamilies, Gallotiinae and Lacertinae,
the latter comprising two monophyletic tribes, the Eremiadini of Africa and arid southwest …

The human genome project has been recently complemented by whole-genome
assessment sequence of 32 mammals and 24 nonmammalian vertebrate species suitable …

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 …

While traditionally species recognition has been based solely on morphological differences
either typological or quantitative, several newly developed methods can be used for a more …

Spatial and temporal constraints on dispersal explain the absence of species from areas
with potentially suitable conditions. Previous studies have shown that post-glacial …

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 …

Among vertebrates, true parthenogenesis is known only in reptiles. Parthenogenetic lizards
of the genus Darevskia emerged as a result of the hybridization of bisexual parental species …

Although sexual reproduction is ubiquitous throughout nature, the molecular machinery
behind it has been repeatedly disrupted during evolution, leading to the emergence of …
