Sizes, proportions and environment

Abstract

The sizes of living organisms range over twenty orders of magnitude. Within the same species, the size of individuals also varies according to the environmental conditions to which they are subjected. From the studies conducted on organisms as diverse as the drosophila, the salamander or the mouse, laws and conserved mechanisms emerge that shed light on the fundamental aspects of growth, but also on more medical issues such as tissue regeneration, metabolic homeostasis and cancer.
