Activation of the embryonic genome during development represents a major developmental transition in all species. The history of its exploration began in the 1950s-1960s, when this idea was put forward and proven experimentally by Alexander Neyfakh. He observed the aberrant development of fish embryos upon X-ray irradiation and noted the different developmental outcomes depending on the stage when fertilized eggs were subjected to irradiation. Neyfakh also discriminated a regional difference of X-irradiation between
