Sean Carroll is a biologist and science writer and in his new book The Serengeti Rules: The Quest to Discover How Life Works and Why it Matters (Princeton University Press) he argues that regulation underpins life at every level and on every conceivable scale.
These are the rules that regulate the amount of every molecule in our bodies and rules that govern how many animals and plants there are in the wild. And according to Professor Carroll, the rules that regulate life are basically the same whether you look down a microscope or examine the whole planet and its ecosystems.
