Ancestors of the alga Volvox made the transition from the solitary life of a single-celled organism to that of a multicellular colony much earlier than previously thought, according to new research. Studying how algae made the leap provides clues to how organisms such as plants and animals evolved from single-celled ancestors. Mediating conflict between the cooperating cells is the key.
