Chromosomes are a central unit of genome organization. One-tenth of all described species
on Earth are butterflies and moths, the Lepidoptera, which generally possess 31 …

The centromere represents a single region in most eukaryotic chromosomes. However,
several plant and animal lineages assemble holocentromeres along the entire chromosome …

Genome structural variations within species are rare. How selective constraints preserve
gene order and chromosome structure is a central question in evolutionary biology that …

The evolution of eukaryotic genomes is accompanied by fluctuations in chromosome
number, reflecting cycles of chromosome number increase (polyploidy and centric fissions) …

The planarian Schmidtea mediterranea is being studied as a model species for
regeneration, but the assembly of planarian genomes remains challenging. Here, we report …

Chromosome rearrangements are thought to promote reproductive isolation between
incipient species. However, it is unclear how often, and under what conditions, fission and …

Chromosome rearrangements are arguably the most dramatic type of mutations, often
leading to rapid evolution and speciation. However, chromosome dynamics have only been …

Significant advances in biophysical methods such as next-generation sequencing
technologies have now opened the way to conduct evolutionary and applied research …

Karyotypes are generally conserved between closely related species and large
chromosome rearrangements typically have negative fitness consequences in …

Understanding the evolutionary origins and factors maintaining alternative life history
strategies (ALHS) within species is a major goal of evolutionary research. While alternative …
