Lateral gene transfer (LGT) is the transmission of genes, sometimes across species barriers, outwith the classic vertical inheritance from parent to offspring. LGT is recognized as an important phenomenon that has shaped the genomes and biology of prokaryotes. Whether LGT in eukaryotes is important and widespread remains controversial. A study...

Loss of sexual reproduction is considered an evolutionary dead end for metazoans, but bdelloid rotifers challenge this view as they appear to have persisted asexually for millions of years1. Neither male sex organs nor meiosis have ever been observed in these microscopic animals: oocytes are formed through mitotic divisions, with no reduction...
