Evolutionary biology is a subfield of biology, concerned with the study of the evolutionary processes that cause diversity of life on Earth. The most significant evolutionary processes are natural selection, speciation and common descent. Some of the branches of this field are evolutionary ecology, evolutionary developmental biology, etc. Research in this field explores speciation and the evolution of ageing, evolvability, sexual reproduction and cooperation. The study of the gene changes due to point mutations, genome duplication and gene duplication is of significant emphasis in this field. The topics included in this book on evolutionary biology are of utmost significance and bound to provide incredible insights to readers. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. Students, researchers, experts and all associated with this field will benefit alike from this book.
