Frail hypotheses in evolutionary biology. [PDF]

open access: yesPLoS Genetics, 2010
In the last decades, under the headings of “mutation strategies,” “evolvability,” or “soft inheritance,” many ideas have been advanced on mechanisms assumed to promote innovative evolution beyond what one may anticipate from the classical model of random mutation and selection.

Biology and Evolutionary Games [PDF]

open access: yes, 2016
This chapter surveys some evolutionary games used in biological sciences. These include the Hawk-Dove game, the Prisoner’s Dilemma, Rock–Paper–Scissors, the war of attrition, the Habitat Selection game, predatorprey games, and signalling games.

Comparative analysis of morabine grasshopper genomes reveals highly abundant transposable elements and rapidly proliferating satellite DNA repeats

open access: yesBMC Biology, 2020
Background Repetitive DNA sequences, including transposable elements (TEs) and tandemly repeated satellite DNA (satDNAs), collectively called the “repeatome”, are found in high proportion in organisms across the Tree of Life.

The evolutionary biology of poxviruses [PDF]

open access: yesInfection, Genetics and Evolution, 2010
The poxviruses (family Poxviridae) are a family of double-stranded viruses including several species that infect humans and their domestic animals, most notably Variola virus (VARV), the causative agent of smallpox. The evolutionary biology of these viruses poses numerous questions, for which we have only partial answers at present.

The Evolutionary Biology of Sex [PDF]

open access: yesCurrent Biology, 2006
In 1861, Charles Darwin wrote "We do not even in the least know the final cause of sexuality; why new beings should be produced by the union of the two sexual elements, instead of by a process of parthenogenesis". It was hardly possible to begin to answer this question at that time, in view of the contemporary lack of knowledge of genetics and cell ...

Ultrastructure of the lamprey head mesoderm reveals evolution of the vertebrate head

open access: yesiScience, 2023
Summary: The cranial muscle is a critical component in the vertebrate head for a predatory lifestyle. However, its evolutionary origin and possible segmental nature during embryogenesis have been controversial.

Phototransduction in a marine sponge provides insights into the origin of animal vision

open access: yesiScience, 2022
Summary: Most organisms respond to light. Here, we investigate the origin of metazoan phototransduction by comparing well-characterized opsin-based photosystems in neural animals with those in the sponge Amphimedon queenslandica.

Evaluating the maintenance of disease-associated variation at the blood group-related gene B4galnt2 in house mice

open access: yesBMC Evolutionary Biology, 2017
Background B4galnt2 is a blood group-related glycosyltransferase that displays cis-regulatory variation for its tissue-specific expression patterns in house mice. The wild type allele, found e.g.
