“Colossal Biosciences said on Wednesday it has succeeded in growing pigeon primordial germ cells, precursor cells to sperm and eggs, for the first time. This is a “pivotal step” in bringing back the dodo, which was a type of pigeon, for the first time in more than 300 years, according to Colossal. The Texas-based company, which has made splashy headlines for its plans to reestablish wooly mammoths and dire wolves, said it has also developed gene-edited chickens that will act as surrogates for the dodos. The chickens will be injected with primordial germ cells from Nicobar pigeons, the closest living relatives of dodos, which will in time, after gene edits to recreate the create the desired body and head shape, allow them to breed dodos.” (09/17/25)
