Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis and the fusion of two gametes of different sexes or mating types. Sex-determination mechanisms are responsible for the sexual fate and development of sexual characteristics in an organism, be it a unicellular alga, a plant, or an animal. In many cases, sex determination is genetic: males and females have different alleles or different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex may be determined by environmental (e.g. temperature) or social variables (e.g. the size of an organism relative to other members of its population). Surprisingly, sex-determination mechanisms are not evolutionarily conserved but are bewilderingly diverse and appear to have had rapid turnover rates during evolution. Evolutionary biologists continue to seek a solution to this conundrum. What drives the surprising dynamics of such a fundamental process that always leads to the same outcome: two sex types, male and female? The answer is complex but the ongoing genomic revolution has already greatly increased our knowledge of sex-determination systems and sex chromosomes in recent years. This novel book presents and synthesizes our current understanding, and clearly shows that sex-determination evolution will remain a dynamic field of future research. The Evolution of Sex Determination is an advanced, research level text suitable for graduate students and researchers in genetics, developmental biology, and evolution.

From the first unicellular life on Earth, living things have had the capacity to sense heat and cold and to avoid extreme temperatures. With the development of a bigger brain and a constant body temperature, mammals were able to change their habitats. The interplay between behavior, body temperature, and ambient temperature may have played a crucial role in human evolution. In this book Carl Gisolfi and Francisco Mora tell the evolutionary story of the brain and thermoregulation, with an emphasis on modern humans.The book first traces the story of the brain throughout evolution and shows how the control of body temperature as a survival mechanism was achieved. It then goes on to discuss the mechanisms of our environmental independence, why a body temperature of 37° C (only five degrees from death) is essential for humans and how this narrow temperature range is defended. It describes how we cope with environmental extremes, the function of fevers, and why thermoregulation is best understood through a combination of physiological and cognitive approaches. It also addresses such questions as "Can we cool the brain?" and "Is the elevation in brain temperature (a hot brain) the reason we stop exercising?"

First Minds: Caterpillars, 'Karyotes, and Consciousness presents a novel theory of the origins of mind and consciousness dubbed the Cellular Basis of Consciousness (CBC). It argues that sentience emerged with life itself. The most primitive unicellular species of bacteria are conscious, though it is a sentience of a primitive kind. They have minds, though they are tiny and limited in scope. Hints that cells might be conscious can be found in the writings of a few cell biologists but a fully developed theory has never been put forward before.Other approaches to the origins of consciousness are examined and shown to be seriously or fatally flawed, specifically approaches based on: (a) the assumption that minds are computational and can be captured by an Artificial Intelligence, (b) efforts to discover the neuro-correlates of mental experiences and, (c) looking for consciousness in less complex species by identifying those that have precursors of those neuro-correlates. Reber shows how each of these approaches is shown to be either essentially impossible (the AI models) or so burdened by philosophical and empirical difficulties that they are effectively unworkable.The CBC approach is developed using standard models of evolutionary biology. The remarkable repertoire of single-celled species that micro- and cell-biologists have discovered is reviewed. Bacteria, for example, have sophisticated sensory and perceptual systems, learn, form memories, make decisions based on information about their environment relative to internal metabolic states, communicate with each other, and even show a primitive form of altruism. All such functions are indicators of sentience.Finally, the implications of the CBC model are discussed along with a number of related issues in evolutionary biology, philosophy of mind, the possibility of sentient plants, the ethical repercussions of universal animal sentience, and the long-range impact of adopting the CBC stance.

Psychoanalyst, political theorist, pioneer of body therapies, prophet of the sexual revolution―all fitting titles, but Wilhelm Reich has never been recognized as a serious laboratory scientist, despite his experimentation with bioelectricity and unicellular organisms. Wilhelm Reich, Biologist is an eye-opening reappraisal of one of twentieth-century science’s most controversial figures―perhaps the only writer whose scientific works were burned by both the Nazis and the U.S. government. Refuting allegations of “pseudoscience” that have long dogged Reich’s research, James Strick argues that Reich’s lab experiments in the mid-1930s represented the cutting edge of light microscopy and time-lapse micro-cinematography and deserve to be taken seriously as legitimate scientific contributions.Trained in medicine and a student of Sigmund Freud, Reich took to the laboratory to determine if Freud’s concept of libido was quantitatively measurable. His electrophysiological experiments led to his “discovery” of microscopic vesicles (he called them “bions”), which Reich hypothesized were instrumental in originating life from nonliving matter. Studying Reich’s laboratory notes from recently opened archives, Strick presents a detailed account of the bion experiments, tracing how Reich eventually concluded he had discovered an unknown type of biological radiation he called “orgone.” The bion experiments were foundational to Reich’s theory of cancer and later investigations of orgone energy.Reich’s experimental findings and interpretations were considered discredited, but not because of shoddy lab technique, as has often been claimed. Scientific opposition to Reich’s experiments, Strick contends, grew out of resistance to his unorthodox sexual theories and his Marxist political leanings.

This book introduces you to the fungi kingdom, from familiar mushrooms to unicellular yeasts. It examines the types of fungi, their reproductive methods, and how they feed. It also looks at modern uses of fungi, as well as how fungi recycle dead organic matter into useful nutrients. Did You Know? There are about 100,000 species of fungi. Some fungi digest their food outside of their bodies. Not counting tree roots, 90 percent of all living matter in forest soil is made up of fungi.

THE WORLD OF PLANTS: A vast world which covers microscopic beings and huge trees 100 metres tall weighing more than 100 tons. Chlorophyll: responsible for photosynthesis. The first plants to appear in the seas were unicellular algae: their evolution and appearance upon dry land. Mosses, ferns, conifers and flowering plants. Characteristics and reproductive devices of each of the above.
