In evolutionary biology, punctuated equilibrium is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history. This state of little or no morphological change is called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another.
Stephen Jay Gould was an American paleontologist, evolutionary biologist, and historian of science. He was one of the most influential and widely read authors of popular science of his generation. Gould spent most of his career teaching at Harvard University and working at the American Museum of Natural History in New York. In 1996, Gould was hired as the Vincent Astor Visiting Research Professor of Biology at New York University, after which he divided his time teaching between there and Harvard.
Wonderful Life: The Burgess Shale and the Nature of History is a 1989 book on the evolution of Cambrian fauna by Harvard paleontologist Stephen Jay Gould.

Gould described his later book Full House (1996) as a companion volume to Wonderful Life.
Loren Eiseley was an American anthropologist, educator, philosopher, and natural science writer, who taught and published books from the 1950s through the 1970s.

At his death, he was Benjamin Franklin Professor of Anthropology and History of Science at the University of Pennsylvania.
Dinosaur in a Haystack is a 1995 book by the paleontologist Stephen Jay Gould. It collects essays culled from Gould's monthly column "The View of Life" published in Natural History magazine, which Gould contributed for 27 years. The book deals with themes familiar to Gould's writing: evolution, science biography, probabilities, and strange oddities found in nature.
Bully for Brontosaurus (1991) is the fifth volume of collected essays by the Harvard paleontologist Stephen Jay Gould. The essays were culled from his monthly column "This View of Life" in Natural History magazine, to which Gould contributed for 27 years. The book deals, in typically discursive fashion, with themes familiar to Gould's writing: evolution and its teaching, science biography, and probabilities.
Richard Swann Lull was an American paleontologist and Sterling Professor at Yale University who is largely remembered now for championing a non-Darwinian view of evolution, whereby mutation(s) could unlock presumed "genetic drives" that, over time, would lead populations to increasingly extreme phenotypes.
Bermuda land snails, scientific name Poecilozonites, are an endemic genus of pulmonate land snail in the family Gastrodontidae. 12 species are known from the fossil record, and 4 of these species survived into modern times, but due to the highly negative effects of human development, that number has been reduced down to two.
The Panda's Thumb: More Reflections in Natural History (1980) is a collection of 31 essays by the Harvard University paleontologist Stephen Jay Gould. It is the second volume culled from his 27-year monthly column "This View of Life" in Natural History magazine. Recurring themes of the essays are evolution and its teaching, science biography, probabilities and common sense.
The Flamingo's Smile: Reflections in Natural History, published in 1985, is the fourth volume of collected essays from evolutionary biologist and well-known science writer Stephen Jay Gould; the essays were culled from his monthly column The View of Life in Natural History magazine, to which Gould contributed for more than two decades. The book deals, in typically discursive fashion, with themes familiar to Gould's writing: evolution and its teaching, science biography, probabilities and common sense.
An Urchin in the Storm is a 1987 essay collection from paleontologist and science writer Stephen Jay Gould.
The Day of the Dinosaur is a science book by L. Sprague de Camp and Catherine Crook de Camp, illustrated with plates. It was first published in hardcover by Doubleday in 1968, and in paperback by Curtis Books in 1970 or 1971. A second hardcover edition was issued by Bonanza Books in 1985. The first chapter was reprinted as "One Day in the Cretaceous" in the de Camps's collection Footprints on Sand.
Ever Since Darwin is a 1977 book by the paleontologist Stephen Jay Gould. Gould's first book of collected essays, it originated from his monthly column "This View of Life," published in Natural History magazine. Edwin Barber—who was then the editorial director for W. W. Norton & Company— encouraged Gould to produce a book. He soon commissioned Gould to write The Mismeasure of Man, but it was not until three years later, when Gould accumulated 33 columns, that it occurred to either of them that the Natural History columns should be published in a single volume. The collection of essays, written between 1973–1977, became a best-seller and propelled Gould to national prominence.
Leonardo's Mountain of Clams and the Diet of Worms (1998) is the eighth volume of collected essays by the Harvard paleontologist Stephen Jay Gould. The essays were culled from his monthly column "The View of Life" in Natural History magazine, to which Gould contributed for 27 years. The book deals, in typically discursive fashion, with themes familiar to Gould's writing: evolution and its teaching, science biography, probabilities and common sense.
I Have Landed (2002) is the 10th and final volume of collected essays by the Harvard paleontologist Stephen Jay Gould. The essays were culled from his monthly column "This View of Life" in Natural History magazine, to which Gould contributed for 27 years. The book deals, in typically discursive fashion, with themes familiar to Gould's writing: evolution and its teaching, science biography, probabilities and common sense.
The Lying Stones of Marrakech (2000) is the ninth volume of collected essays by the Harvard paleontologist, Stephen Jay Gould. The essays were culled from his monthly column "The View of Life" in Natural History magazine, to which Gould contributed for 27 years.

Henry Edward Crampton was an American evolutionary biologist and malacologist who specialized in land snails. Crampton undertook the first major study of evolution in nature in his research in the Society Islands. Crampton made twelve separate expeditions over the course of his career to Moorea near Tahiti to study the land snail genus Partula, while years more were spent measuring and cataloguing his specimens. In all, he dedicated nearly half-a-century to the study.
Donald Ross Prothero is an American geologist, paleontologist, and author who specializes in mammalian paleontology and magnetostratigraphy, a technique to date rock layers of the Cenozoic era and its use to date the climate changes which occurred 30-40 million years ago. He is the author or editor of more than 30 books and over 300 scientific papers, including at least 5 geology textbooks.
Certain Personal Matters is an 1897 collection of essays selected by H. G. Wells from among the many short essays and ephemeral pieces he had written since 1893. The book consists of thirty-nine pieces ranging from about eight hundred to two thousand words in length. A one-shilling reprint was issued in 1901 by T. Fisher Unwin.
Roger Lansing Grande, more commonly known as Lance Grande, is an evolutionary biologist and curatorial scientist. His research and work is focused on Paleontology, Ichthyology, Systematics and Evolution. He is best known for his work on the paleontology of the Green River Formation and for his detailed monographs on the comparative anatomy and evolution of ray-finned fishes.
