Evolutionary biology is a subfield of biology concerned with the study of evolutionary processes, which are at the core of the emergence of complex and diverse life on Earth. Among these processes are the mechanisms of common descent, natural selection and speciation. The genetic architecture of adaptation, molecular evolution, and the forces of sexual selection, biogeography and genetic drift are explored and studied under the domain of evolutionary biology. Research in evolutionary biology covers diverse themes from molecular genetics to computer science. One dimension of research strives to explain the phenomena of speciation and evolvability, and the evolution of aging, cooperation and sexual reproduction. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of evolutionary biology. It presents this complex subject in the most comprehensible and easy to understand language. For someone with an interest and eye for detail, this book covers the most significant topics in this field.
