Gaia philosophy is a broadly inclusive term for relating concepts about, humanity as an effect of the life of this planet.
The noosphere is a philosophical concept developed and popularized by the biogeochemist Vladimir Vernadsky and philosopher and Jesuit priest Pierre Teilhard de Chardin. Vernadsky defined the noosphere as the new state of the biosphere, and described it as the planetary "sphere of reason". The noosphere represents the highest stage of biospheric development, that of humankind's rational activities.
Vladimir Ivanovich Vernadsky, also spelt Volodymyr Ivanovych Vernadsky was a Russian, Ukrainian, and Soviet mineralogist and geochemist who is considered one of the founders of geochemistry, biogeochemistry, and radiogeology. He was one of the founders and the first president of the Ukrainian Academy of Sciences. Vladimir Vernadsky is most noted for his 1926 book The Biosphere in which he inadvertently worked to popularize Eduard Suess' 1875 term biosphere, by hypothesizing that life is the geological force that shapes the earth. In 1943 he was awarded the Stalin Prize. Vernadsky's portrait is depicted on the Ukrainian ₴1,000 hryvnia banknote.
Symbiosis is any type of a close and long-term biological interaction between two biological organisms of different species, termed symbionts, be it mutualistic, commensalistic, or parasitic. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term is sometimes used in the more restricted sense of a mutually beneficial interaction in which both symbionts contribute to each other's support.
Lynn Margulis was an American evolutionary biologist, and was the primary modern proponent for the significance of symbiosis in evolution. In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei by proposing it to have been the result of symbiotic mergers of bacteria. Margulis was also the co-developer of the Gaia hypothesis with the British chemist James Lovelock, proposing that the Earth functions as a single self-regulating system, and was the principal defender and promulgator of the five kingdom classification of Robert Whittaker.
Symbiogenesis is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms. The theory holds that mitochondria, plastids such as chloroplasts, and possibly other organelles of eukaryotic cells are descended from formerly free-living prokaryotes taken one inside the other in endosymbiosis. Mitochondria appear to be phylogenetically related to Rickettsiales bacteria, while chloroplasts are thought to be related to cyanobacteria.
Daisyworld, a computer simulation, is a hypothetical world orbiting a star whose radiant energy is slowly increasing or decreasing. It is meant to mimic important elements of the Earth-Sun system. James Lovelock and Andrew Watson introduced it in a paper published in 1983 to illustrate the plausibility of the Gaia hypothesis. In the original 1983 version, Daisyworld is seeded with two varieties of daisy as its only life forms: black daisies and white daisies. White petaled daisies reflect light, while black petaled daisies absorb light. The simulation tracks the two daisy populations and the surface temperature of Daisyworld as the sun's rays grow more powerful. The surface temperature of Daisyworld remains almost constant over a broad range of solar output.
A superorganism, or supraorganism, is a group of synergetically-interacting organisms of the same species. A community of synergetically-interacting organisms of different species is called a holobiont.
The Gaia hypothesis, also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet.
Microbial ecology is the ecology of microorganisms: their relationship with one another and with their environment. It concerns the three major domains of life—Eukaryota, Archaea, and Bacteria—as well as viruses.
Homeorhesis, derived from the Greek for "similar flow", is a concept encompassing dynamical systems which return to a trajectory, as opposed to systems which return to a particular state, which is termed homeostasis.
William Irwin Thompson was an American social philosopher, cultural critic, and poet. He received the Oslo International Poetry Festival Award in 1986. He described his writing and speaking style as "mind-jazz on ancient texts". He was the founder of the Lindisfarne Association, which proposed the study and realization of a new planetary culture.
What Is Life? The Physical Aspect of the Living Cell is a 1944 science book written for the lay reader by physicist Erwin Schrödinger. The book was based on a course of public lectures delivered by Schrödinger in February 1943, under the auspices of the Dublin Institute for Advanced Studies, where he was Director of Theoretical Physics, at Trinity College, Dublin. The lectures attracted an audience of about 400, who were warned "that the subject-matter was a difficult one and that the lectures could not be termed popular, even though the physicist’s most dreaded weapon, mathematical deduction, would hardly be utilized." Schrödinger's lecture focused on one important question: "how can the events in space and time which take place within the spatial boundary of a living organism be accounted for by physics and chemistry?"
Tyler Volk is Professor Emeritus of Environmental Studies and Biology at New York University.
Research concerning the relationship between the thermodynamic quantity entropy and both the origin and evolution of life began around the turn of the 20th century. In 1910 American historian Henry Adams printed and distributed to university libraries and history professors the small volume A Letter to American Teachers of History proposing a theory of history based on the second law of thermodynamics and on the principle of entropy.
Biological organisation is the organisation of complex biological structures and systems that define life using a reductionistic approach. The traditional hierarchy, as detailed below, extends from atoms to biospheres. The higher levels of this scheme are often referred to as an ecological organisation concept, or as the field, hierarchical ecology.
Jan Anthony Sapp is a professor in the Department of Biology, York University, Canada. His writings focus especially on evolutionary biology beyond the classical neo-Darwinian framework, and emphasize the fundamental importance of symbiosis and horizontal gene transfer in heredity and evolution.
Dactyl Foundation is a 501 (c)(3) not-for-profit arts organization in New York City founded by New York-based artist Neil Grayson and novelist/philosopher of science V.N. Alexander.
Novel ecosystems are human-built, modified, or engineered niches of the Anthropocene. They exist in places that have been altered in structure and function by human agency. Novel ecosystems are part of the human environment and niche, they lack natural analogs, and they have extended an influence that has converted more than three-quarters of wild Earth. These anthropogenic biomes include technoecosystems that are fuelled by powerful energy sources including ecosystems populated with technodiversity, such as roads and unique combinations of soils called technosols. Vegetation associations on old buildings or along field boundary stone walls in old agricultural landscapes are examples of sites where research into novel ecosystem ecology is developing.
Harold Joseph Morowitz was an American biophysicist who studied the application of thermodynamics to living systems. Author of numerous books and articles, his work includes technical monographs as well as essays. The origin of life was his primary research interest for more than fifty years. He was the Robinson Professor of Biology and Natural Philosophy at George Mason University after a long career at Yale.
