The high cost of complexity: New study explores energy needs of multicellular life

Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring billion," the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicellular forms. This era set the stage for the later emergence of complex multicellular life, marking a key chapter in evolutionary history.
