Theory Of Evolution

An instructive introduction to the theory of evolution and its applications in biology, physics, chemistry, geology and humanities. The author shows that evolution is a physical process, occurring in geological time dimension, describes how the Darwin’s theory of natural selection works in immunology, neurobiology, sociology as well as in certain aspects of culture and political institutions. He also shows the effects achieved through the action of selection in different areas of biological and social life. He discusses such problems as: the ambiguity of the term “theory of evolution”, the falsifiability of evolutionary hypotheses, connection between evolution and thermodynamics, the concept of reductionism, methodological background of phylogenetics, cladistics, evolutionary developmental biology and homeotic genes, as well as the cumulative nature of social and cultural evolution.

A new 1-MeV transmission electron microscope (Model JEM-1000) was installed at the Department of Molecular, Cellular and Developmental Biology of the University of Colorado in Boulder during the summer and fall of 1972 under the sponsorship of the Division of Research Resources of the National Institutes of Health. The installation was completed in October, 1972. It is installed primarily for the study of biological materials without many of the limitations hitherto unavoidable in standard transmission electron microscopy. Only the technical characteristics of the installation are briefly reviewed here. A more detailed discussion of the experimental program under way is being published elsewhere.

Samuel Fessenden Clarke was the leading specialist on hydroids (phylum Cnidaria) in North America over the last quarter of the nineteenth century. During that period he published taxonomic papers on hydroids from both the Atlantic and Pacific coasts of the continent, from the Gulf of Mexico, and from the eastern Pacific off Central and South America. He also authored a section on hydrozoan biology for “The Riverside Natural History” series. Most of his papers on hydroids were published while he was in his twenties. Clarke described as new 61 nominal species, three nominal genera, and one nominal family, as well as two “varieties” of hydroids. A list of these, and their current taxonomic status, appears in the present work. Clarke consistently provided sound descriptions and locality data for all supposed new species, and drew accurate illustrations of most of them. His research on Hydrozoa, beyond alphataxonomy, was directed towards faunal distributions and the use of hydroid assemblages as biogeographic indicators. In addition to investigations on hydroids, Clarke carried out research on the developmental biology of amphibians and reptiles. His doctoral dissertation at Johns Hopkins University was based on the embryology of the “Spotted Salamander” (=Yellow-spotted Salamander), and he published a major paper on the habits and embryology of the American Alligator. Most of Clarke's career was devoted to academic duties at Williams College, Massachusetts, where he was recognized as a dedicated and inspiring teacher. He served the American Society of Naturalists in various capacities, including a term as its president, was an influential trustee of the Marine Biological Laboratory, Woods Hole, and promoted the study of science in American schools.

Living Being

Evolution is continuous process of changes in structural and physiological mechanism in living being. Microbes/pathogens can evolve naturally or artificially and become resistant to various medicines. Novel coronavirus is such evolved pathogen of coronavirus group. Enough strong immunity is needed to prevent or survive from COVID-19 pandemic. Ayurveda provides ways for evolving physiological responses to built immunity. Present work is brief attempt to increase insight in this filed.Present review was done based on simple theory of evolution, recent updates regarding prevention of COVID-19, Ayurveda aspect toward infectious diseases and Ayurveda ways towards prevention of infectious diseases with special reference to COVID-19. Person with impaired immunity is more susceptible for COVID-19 and thus immunity is an important preventing factor. Ayurveda Rasayana (rejuvanation) herbs, Yoga exercises, Pranayama (special breathing exercise), daily regimens and personal hygiene guidelines can be helpful strategies in controlling the spread of COVID-19.The preventive aspects of pandemic situations are narrated in Ayurveda with enough details. These ways need to be scientifically explored and refined for precision. As prevention is always better than cure hence Ayurveda ways can be considered for future strategies to avoid pandemics such as COVID-19.  There is great need of research on Ayurveda medicines on COVID-19 like diseases.
