In this book the authors draw on what is known, largely from recent research, about the nature of genes and cells, the genetics of development and animal and plant body plans, intra- and interorganismal communication, sensation and perception, to propose that a few basic generalizations, along with the modified application of the classical evolutionary theory, can provide a broader theoretical understanding of genes, evolution, and the diverse and complex nature of living organisms.
By the end of the last century, it was known from microscopic studies that most cells contain small elongated bodies (mitochondria). It has recently been discovered that their true function is as complex organelles possessing inner and outer membranes and even their own DNA.
