Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Epigenetic structures appear to reduce the rate of changes in genes essential for survival and reproduction, a study finds, challenging the notion that mutations are evenly distributed throughout the genome prior to selection.
Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different process.
Parents’ mutations, even if they’re not inherited by offspring, could affect subsequent generations through changes to epigenetic marks, a study finds.
