Researchers question whether epigenetic reprogramming is unique to eutherian mammals
Original: Is genome-wide epigenetic reprogramming a eutherian innovation?
A discussion piece in Nature asks whether genome-wide epigenetic reprogramming—the extensive erasure and re-establishment of chemical marks on DNA during early development—is an innovation specific to eutherian (placental) mammals. Researchers are weighing comparative evidence across species to determine when this wholesale reprogramming emerged in evolution and whether other animals use narrower or different mechanisms to reset their genomes.
Why now: A new Nature commentary is prompting debate among biologists about the evolutionary origins of epigenetic reprogramming.
