Nature retains the same relative scales throughout and between all living things.
Now a Laboratory particle physicist has teamed with ecologists to devise a model that explains why all biological systems are inherently similar. The model offers profound implications for macroscopic aspects of biology. The answer, he believed, was essential to understanding how evolution maximizes fitness. An animal 100 times larger than a mouse will not have a metabolic rate 100 times higher, as might be expected since it has so many more cells to feed. Its metabolic rate will, in fact, be only about 30 times higher in this case, following a consistent and predictable formula.
