Emergent properties result from complex, nonlinear interactions of the different components. For example, suppose someone broke down a car into its nuts and bolts and pieces and laid them out on a floor.

Could you predict that, properly assembled, these bits of metal and plastic would become a vehicle capable of converting the energy in gasoline into movement? Who could predict that the right combination of elements into molecules and assemblages of molecules would result in a living organism?

Among the most complex emergent properties in humans are emotion, intelligence, and other aspects of brain function. None of these properties can be predicted from knowing the individual properties of nerve cells. When the Human Genome Project www. However, as research advanced, scientists had to revise their original idea that a given segment of DNA contained one gene that coded for one protein. It became clear that one gene may code for many proteins. The Human Genome Project ended in , but before then researchers had moved beyond genomics to proteomics, the study of proteins in living organisms.

Now scientists have realized that knowing that a protein is made in a particular cell does not always tell us the significance of that protein to the cell, the tissue, or the functioning organism. The exciting new areas in biological research are called functional genomics, systems biology, and integrative biology, but fundamentally these are all fields of physiology.

The integration of function across many levels of organization is a special focus of physiology. To integrate means to bring varied elements together to create a unified whole. Do you like this book?
