摘要
The diversification of life involved enormous increases in size and complexity. The 演化ary transitions from prokaryotes to unicellular eukaryotes to metazoans were accompanied by major innovations in metabolic design. Here we show that the 縮放律s of metabolic rate, 族群 growth rate, and production efficiency with body size have changed across the 演化ary transitions. Metabolic rate scales with body mass superlinearly in prokaryotes, linearly in protists, and sublinearly in metazoans, so Kleiber's 3/4 power 縮放律 law does not apply universally across organisms. The 縮放律 of maximum 族群 growth rate shifts from positive in prokaryotes to negative in protists and metazoans, and the efficiency of production declines across these groups. Major changes in metabolic processes during the early 演化 of life overc
