The age-old question—what came first, the chicken or the egg? A team from the University of Geneva may finally have cracked it, thanks to a billion-year-old organism called Chromosphaera perkinsii. Found in marine sediments near Hawaii, this tiny single-celled organism formed multicellular structures long before chickens or even animals existed. This discovery suggests eggs existed well before chickens, dating back to the age of dinosaurs. But does this solve the ‘chicken egg’ question? Dive into the science and let us know: are you Team Chicken or Team Egg?
