This book provides an evolutionary conceptual framework for comparative genomics with the
ultimate objective of understanding the loss and gain of genes during evolution the
interactions among gene products and the relationship between genotype phenotype and the
environment. The many examples in the book have been carefully chosen from primary research
literature based on two criteria: their biological insight and their pedagogical merit. The
phylogeny-based comparative methods involving both continuous and discrete variables often
represent a stumbling block for many students entering the field of comparative genomics. They
are numerically illustrated and explained in great detail. The book is intended for researchers
new to the field i.e. advanced undergraduate students postgraduates and postdoctoral fellows
although professional researchers who are not in the area of comparative genomics will also
find the book informative.
