For generations, the emergence of multicellular life has been treated as a mystery locked inside the genome — a secret written in code, waiting to be read. Researchers at Caltech now propose a quieter, more elemental explanation: that physical pressure, not genetic innovation, may have first taught cells to live together. When cells crowd and compress, oxygen and nutrients grow scarce at the center, and the imbalance that follows — hollowing, folding, branching — may be less a biological miracle than an inevitable answer physics offers to a spatial problem. In this view, the architecture of al
