Theodosius Grigorievich Dobzhansky was an American geneticist and evolutionary biologist. He was a central figure in the field of evolutionary biology for his work in shaping the modern synthesis and also popular for his support and promotion of theistic evolution as a practicing Christian. Born in the Russian Empire, Dobzhansky immigrated to the United States in 1927, aged 27.
Robert Marshall Axelrod is an American political scientist. He is Professor of Political Science and Public Policy at the University of Michigan where he has been since 1974. He is best known for his interdisciplinary work on the evolution of cooperation. His current research interests include complexity theory, international security, and cyber security. His research includes innovative approaches to explaining conflict of interest, the emergence of norms, how game theory is used to study cooperation, and cross-disciplinary studies on evolutionary processes.
George Gaylord Simpson was an American paleontologist. Simpson was perhaps the most influential paleontologist of the twentieth century, and a major participant in the modern synthesis, contributing Tempo and Mode in Evolution (1944), The Meaning of Evolution (1949) and The Major Features of Evolution (1953). He was an expert on extinct mammals and their intercontinental migrations. Simpson was extraordinarily knowledgeable about Mesozoic fossil mammals and fossil mammals of North and South America. He anticipated such concepts as punctuated equilibrium and dispelled the myth that the evolution of the horse was a linear process culminating in the modern Equus caballus. He coined the word hypodigm in 1940, and published extensively on the taxonomy of fossil and extant mammals. Simpson was influentially, and incorrectly, opposed to Alfred Wegener's theory of continental drift, but accepted the theory of plate tectonics when the evidence became conclusive.
Niles Eldredge is an American biologist and paleontologist, who, along with Stephen Jay Gould, proposed the theory of punctuated equilibrium in 1972.
George Ledyard Stebbins Jr. was an American botanist and geneticist who is widely regarded as one of the leading evolutionary biologists of the 20th century. Stebbins received his Ph.D. in botany from Harvard University in 1931. He went on to the University of California, Berkeley, where his work with E. B. Babcock on the genetic evolution of plant species, and his association with a group of evolutionary biologists known as the Bay Area Biosystematists, led him to develop a comprehensive synthesis of plant evolution incorporating genetics.
Pagurapseudidae is a family of crustaceans in the order Tanaidacea. Like hermit crabs, they inhabit empty gastropod shells, but can be told apart from hermit crabs by the lack of a carapace, revealing the segmentation of the thorax, and by the greater number of legs: hermit crabs have five pairs of legs, of which the first has large claws, and the last is highly reduced, while in Pagurapseudidae, there is one pair of claws, plus six further walking legs.
Francisco José Ayala Pereda was a Spanish-American evolutionary biologist and philosopher who was a longtime faculty member at the University of California, Irvine, and University of California, Davis.
Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells.
The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda. Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is drawn into the mantle cavity and over the gill and which serves as a chemoreceptor to locate food. Siphonal canals allow for active transport of water to sensory organs inside the shell. Organisms without siphonal canals in their shells rely on passive or diffuse transport or water into their shell. Those with siphonal canals have a direct inhalant stream of water that interacts with sensory organs to detect concentration and direction of a stimulus, such as food or mates. In certain groups of carnivorous snails, where the siphon is particularly long, the structure of the shell has been modified in order to house and protect the soft structure of the siphon. Thus the siphonal canal is a semi-tubular extension of the aperture of the shell through which the siphon is extended when the animal is active.
The Mesozoic marine revolution (MMR) refers to the increase in shell-crushing (durophagous) and boring predation in benthic organisms throughout the Mesozoic era, along with bulldozing and sediment remodelling in marine habitats. The term was first coined by Geerat J. Vermeij, who based his work on that of Steven M. Stanley. While the MMR was initially restricted to the Cretaceous, more recent studies have suggested that the beginning of this ecological/evolutionary arms race extends as far back as the Triassic, with the MMR now being considered to have started in the Anisian or the Aalenian. It is an important transition between the Palaeozoic evolutionary fauna and the Modern evolutionary fauna that occurred throughout the Mesozoic.
The Escalation Hypothesis is an evolutionary theory in biology put forward by Geerat J. Vermeij. It states that organisms are in constant conflict with one another and therefore devote many resources to thwarting the adaptations evolution brings to all competing organisms as time advances. This is in contrast to adaptations evolution may bring that are unrelated to competition with other organisms such as adapting to ecological niches based upon other factors such as geology and climate.
Olivellinae, are a subfamily of small predatory sea snails with smooth, shiny, elongated oval-shaped shells, in the family Olividae. The shells sometimes show muted but attractive colors, and may have some patterning.
The Daniel Giraud Elliot Medal is awarded by the U.S. National Academy of Sciences "for meritorious work in zoology or paleontology study published in a three to five year period." Named after Daniel Giraud Elliot, it was first awarded in 1917.
Isabel Patricia Montañez is a paleoclimatologist specializing in geochemical records of ancient climate change. She is a distinguished professor and a Chancellor's Leadership Professor in the department of earth and planetary sciences at University of California, Davis. As of 2021, Montañez is the director of the UC Davis Institute of the Environment.
Scott P. Carroll is an American evolutionary biologist and ecologist affiliated with the University of California, Davis and the University of Queensland. Carroll's main interests are in exploring contemporary evolution to better understand adaptive processes and how those processes can be harnessed to develop solutions to evolutionary challenges in food production, medical care and environmental conservation. With Charles W. Fox, Carroll edited Conservation Biology: Evolution in Action, a book published by Oxford University Press in 2008 in which contributors, across the field of evolutionary biology and conservation, apply evolutionary thinking to concepts and practices in conservation biology, an area of research sometimes called evolutionary ecology. Carroll is founding director of the Institute for Contemporary Evolution.
Jonathan B. Losos is an American evolutionary biologist, herpetologist and ailurologist.
David P. Mindell is an American evolutionary biologist and author. He is currently a senior researcher at the University of California, Berkeley, Museum of Vertebrate Zoology. Mindell's work is focused on the systematics, conservation and molecular evolution of birds, especially birds of prey. He is known for his 2006 book, The Evolving World in which he explained, for the general public, how evolution applies to everyday life.
Lirabuccinum dirum, commonly known as the dire whelk, the spindle shell or the spindle whelk, is a species of sea snail, a marine gastropod mollusk in the family Tudiclidae, the true whelks.
Anthony David Barnosky is an ecologist, geologist and biologist (paleoecology). He was Professor at the Department of Integrative Biology at UC Berkeley until his retirement. His research is concerned with the relationship between climate change and mass extinctions.
