Nothing in Evolution Makes Sense Except in the Light of Genomics: Read–Write Genome Evolution as an Active Biological Process

open access: yesBiology, 2016
The 21st century genomics-based analysis of evolutionary variation reveals a number of novel features impossible to predict when Dobzhansky and other evolutionary biologists formulated the neo-Darwinian Modern Synthesis in the middle of the last century.

Climate, geographic distribution and viviparity in Liolaemus (Reptilia; Squamata) species: when hypotheses need to be tested [PDF]

open access: yes, 2014
La distribución de los reptiles, dada su dependencia de la temperatura, puede verse restringida en función del clima. En particular, se han planteado tres hipótesis que vinculan el clima con la distribución y el viviparismo en las especies de reptiles: i)

Viviparity imparts a macroevolutionary signature of ecological opportunity in the body size of female Liolaemus lizards

open access: yesNature Communications
Viviparity evolved ~115 times across squamate reptiles, facilitating the colonization of cold habitats, where oviparous species are scarce or absent. Whether the ecological opportunity furnished by such colonization reconfigures phenotypic diversity and ...

Primordial Germ Cell Development in the Poeciliid, Gambusia holbrooki, Reveals Shared Features Between Lecithotrophs and Matrotrophs

open access: yesFrontiers in Cell and Developmental Biology, 2022
Metazoans exhibit two modes of primordial germ cell (PGC) specification that are interspersed across taxa. However, the evolutionary link between the two modes and the reproductive strategies of lecithotrophy and matrotrophy is poorly understood.

Morphogenesis of propagules in viviparous species Bryophyllum daigremontianum and B. calycinum

open access: yesActa Societatis Botanicorum Poloniae, 2014
The propagule development in two viviparous Bryophyllum species: B. daigremontianum and B. calycinum (Crassulaceae) has been found to proceed via embryoidogenesis (somatic embryo).
