Introduction

page 1: The solar system
Is life on Earth unique in the
universe? To think about this question, we must look at the
environment in which life has arisen on earth. This environment is
the solar system: the sun, a star, radiating huge amounts of energy.
Some of this energy falls on a planet which has just the right
conditions for the evolution of life? What are those conditions? What
is life?
page 2: Thermodynamics
A living thing is a system, that
is an ordered set of processes. Our first step toward understanding
life is to consider the relationships between order and disorder
revealed by classical mechanics. When generalised through statistical
mechanics to information theory, thermodynamic ideas can be applied
to all systems, and give us some broad bounds on the conditions in
which life can exist.
page 3: Reproduction
The key to order is
reproduction. By maintaining a coded copy from which they can
regenerate themselves, living things are able produce clean copies of
themselves, so overcoming for the lineage the accumulation of wear
and tear that leads to the death of any individual. More than two
thousand years ago Plato saw that error free abstract entities
(ideas) preserved the structure of the real world. Let us call these
abstract entities texts. They have no life of their own, but they
encode life and can be manipulated by life. Just like the books and
other media in which cultural information is encoded and reproduced.
page 4: Evolution
As the genes constrain life, so
life constrains the genes. How every creature on earth works is
defined partly by its genes and partly by its environment. The
planetary environment is unstable at all scales of space and time.
There are local and global changes, fast ones and slow ones. The most
majestic determinants of the global environment seem to be the slow
movements of the land masses and the slow evolution of the earth's
orbit and orientation with respect to the sun. Darwin realised that
creatures that do not fit their environment do not survive. On the
other hand, life is so powerful that it also changes its environment.
The result is process of evolution which leaves in its tracks the
tree of life.
