Holokinetic chromosomes reshape but not accelerate insect genome evolution
Original: Holokinetic chromosomes reshape—but do not accelerate—insect genome evolution
New research on holokinetic chromosomes—chromosomes without a localized centromere, found in insects such as butterflies and some beetles—indicates they restructure genomes in distinctive ways, but do not speed up the overall pace of genome evolution. The findings refine how scientists understand chromosomal change and genetic diversity in holokinetic insect lineages, challenging assumptions that this chromosome type accelerates evolutionary rates.
Why now: New research challenges the assumption that holokinetic chromosomes speed up genome evolution in insects.
