This book discusses advanced topics in morphometrics, for adopting its application to systematics, environmental change and ontogenetic adaptation. It is human tendency to measure things, and this applies in science as well as day-to-day life. As our comprehension of epigenetics and genetic control mechanisms has enhanced over the past numerous decades, it has become vivid that morphometric evaluation continues to be essential to our complete understanding of natural variability in growth and form. The enormous progress of our knowledge base in the past century has necessitated that we look for novel methods to measure and map more detail as well as more numbers of parameters among individuals and populations. The book will serve as a reference to a broad spectrum of readers.
