Journal of Evolutionary Biochemistry and Physiology publishes experimental and review articles on comparative and ontogenetic physiology and biochemistry, as well as on the evolution of functions, morphology, pharmacology, pathophysiology, and ecological physiology. The journal publishes both original articles in the English language and English translations of selected articles from two Russian-language journals: Zhurnal Evolyutsionnoi Biokhimii i Fiziologii (main source) and Rossiiskii Fiziologicheskii Zhurnal imeni I.M. Sechenova (additional source). The source of each article is described at the article level on the title pages. The final decision about the publication in Journal of Evolutionary Biochemistry and Physiology is made by its editorial board regardless of the source. The editorial and peer review policies and ethical principles are the same for all translated and original articles. The journal welcomes manuscripts from all countries. PEER REVIEW Journal of Evolutionary Biochemistry and Physiology is a peer reviewed journal. We use a single blind peer review format. The average period from submission to first decision is 41 days. The average rejection rate for submitted manuscripts is 35%. The final decision on the acceptance of an article for publication is made by the Deputy Editor-in-Chief. Any invited reviewer who feels unqualified or unable to review the manuscript due to the conflict of interests should promptly notify the editors and decline the invitation. Reviewers should formulate their statements clearly in a sound and reasoned way so that authors can use reviewer’s arguments to improve the manuscript. Personal criticism of the authors must be avoided. Reviewers should indicate in a review (i) any relevant published work that has not been cited by the authors, (ii) anything that has been reported in previous publications and not given appropriate reference or citation, (ii) any substantial similarity or overlap with any other manuscript (published or unpublished) of which they have personal knowledge. Detailed coverage of evolution of the main forms of metabolism in connection with life origin Discusses problems of the evolution of functions Covers morphology, pharmacology, pathophysiology and ecological physiology
