Genetic variation, which is generated by mutation, recombination and gene flow, can reduce
the mean fitness of a population, both now and in the future. This 'genetic load'has been …

Transposable elements (TEs) are selfish genetic elements that mobilize in genomes via
transposition or retrotransposition and often make up large fractions of vertebrate genomes …

Animal genomes show networks of deeply conserved gene linkages whose phylogenetic
scope and chromosomal context remain unclear. Here, we report chromosome-scale …

Although it is widely believed that early vertebrate evolution was shaped by ancient whole-
genome duplications, the number, timing and mechanism of these events remain elusive …

Ancient polyploidization events have had a lasting impact on vertebrate genome structure,
organization and function. Some key questions regarding the number of ancient …

Sturgeons seem to be frozen in time. The archaic characteristics of this ancient fish lineage
place it in a key phylogenetic position at the base of the~ 30,000 modern teleost fish …

Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

Microchromosomes are prevalent in nonmammalian vertebrates [PD Waters et al., Proc.
Natl. Acad. Sci. USA 118 (2021)], but a few of them are missing in bird genome assemblies …

Whole genome duplication (WGD) is a dramatic evolutionary event generating many new
genes and which may play a role in survival through mass extinctions. Paddlefish and …

Lungfishes are the closest extant relatives of tetrapods and preserve ancestral traits linked
with the water-to-land transition. However, their huge genome sizes have hindered …
