Darwin's theory of
evolution explains much about how humans and other animals change
over time. However, even Darwin felt that his theory was incomplete.
He wrote that he was convinced that Natural selection was the main
but not exclusive means of modification. Lamarck, a contemporary of
Darwin's had a theory that internal factors were responsible for
modification. He believed that modification was based on what an
organism's environment required and how the organism related to that
environment.
Although not
espousing Lamarck's theory, the present book stresses the importance
of internal factors, particularly in the evolution of humans. The
authors believe that today's environment for humans is safer than in
the past, and therefore humans have more opportunity to effect
changes in themselves. His chapters on why we die and on mind-body
medicine are interesting in this context.
The book, although
presenting complex concepts, is relatively easy to read. The authors
use analogies, such as a card game for how the information cycle
allows for internal processes to bring about changes and help the
organism maintain it's present status. It also helps to have some
passing familiarity with information theory, although the authors do
a good job of explaining the concepts.
The concepts
presented are not a way to negate Darwin's theory. They are rather a
thought provoking set of ideas designed to enhance the theory. I
recommend this book. While it may not be factually accurate, in fact
it is based on theory not research, it is well worth reading for the
ideas.
I reviewed this book
for Net Galley.
