We are living in a computer-based world. Computer use in various fields has long
ceased to be fashionable and has become almost a necessity. Since the early phases of
design to the final implementation of a product, the computer has replaced traditional
tools, providing efficient and elegant instruments. We can say, without fear of being
wrong, that the strides that mankind has taken in recent decades is due largely to
This book is an exploration of the evolutionary process of natural hybridization.
My motivation for writing this book comes from the view that crosses between
genetically divergent individuals have a major influence on the evolution of
some plant and animal species complexes. In particular, I want to examine the
role that natural hybridization has as a creative force in organismal evolution. I
realize that my emphasis on the "creative" aspect of natural hybridization could
lead some to conclude that I believe that this is the only possible outcome
from hybridization and gene exchange....
