Biochemical Evolution focuses on the processes, approaches, and methodologies involved in biochemical evolution, including biochemical systems, digestion, metabolism, and morphology. The publication first offers information on the unity of the biochemical plan of animals, dissimilarities, and evolution of biochemical constituents, as well as biochemical analogs and homologs and evolution of biochemical constituents. The text then ponders on orthogenetic evolution of biochemical systems and biochemical adaptations. Discussions focus on respiratory function, hydrolytic processes of digestion, protein metabolism, ammonemia, domain of glucemia, and marine, fresh-water, and terrestrial animals. The manuscript takes a look at systematic characters, including the biochemical characteristics of vertebrates, tunicates, cyclostomes, elasmobranchs, insects, sipunculids, and the taxonomy of biochemical characteristics. The text then tackles perspectives, as well as mechanism of biochemical evolution, biochemistry and morphology, and irreversibility of lost biochemical characters. The book is a dependable source of data for readers interested in biochemical evolution.
