During the past quarter century, molecular phylogenetic inferences have significantly
resolved evolutionary relationships spanning the eukaryotic tree of life. With improved …

In most eukaryotes, the kinetochore protein complex assembles at a single locus termed the
centromere to attach chromosomes to spindle microtubules. Holocentric chromosomes have …

DNA sequences, powerful for phylogeny, have not yet proven as rewarding for taxonomic
categorization purposes. However, further analyses of one locus, the second Internal …

Genomes of numerous diploid plant and animal species possess traces of interspecific
crosses, and many researches consider them as support for homoploid hybrid speciation …

Biologists have long theorized about the evolution of life cycles, meiosis, and sexual
reproduction. We revisit these topics and propose that the fundamental difference between …

Comparative genetics, genomics and cytogenetics provide tools to trace the evolutionary
history of extant genomes. Yet, the interpretation of rapidly increasing genomic data is not …

Chromosomal rearrangements trigger speciation by acting as barriers to gene flow.
However, the underlying theory was developed with monocentric chromosomes in mind …

New initiatives to sequence complete genomes of related organisms have introduced a new
era of large-scale evolutionary genomics. The comparative analysis of these genomes …

Background The origin of eukaryote-specific traits such as mitosis and sexual reproduction
remains disputable. There is growing evidence that both mitosis and eukaryotic sex (ie, the …

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