How reliable is the biological time clock?
Ángel López-Urrutia A theoretical framework that describes the effect of temperature and body size on biological processes has long been sought. Gillooly et al.1 use an elegant combination of the first principles of biochemical kinetics and allometric growth to derive a general definition of biological time by which, simply from a knowledge of how warm and how large an animal is, it is possible to calculate how long it will take to develop.
