Extinction Theory

Why did the dinosaurs and two-thirds of all living species vanish from the face of the Earth sixty-five million years ago? Throughout the history of life a small number of catastrophic events have caused mass extinction, and changed the path of evolution forever. Two main theories have emerged to account for these dramatic events: asteroid impact, and massive volcanic eruptions, both leading to nuclear-like winter. In recent years, the impact hypothesis has gained precedence, but Vincent Courtillot suggests that cataclysmic volcanic activity can be linked not only to the K-T mass extinction, but to most of the main mass extinction events in the history of the Earth. Courtillot's book debunks some of the myths surrounding one of the most controversial arguments in science. This story will fascinate everyone interested in the history of life and death on our planet.

For the Fourth Edition, new theoretical approaches, such as agency, materiality, and engagement theory, are added and earlier approaches analyzed afresh. Field methods and scientific techniques have been updated throughout, and new emphasis is placed on climate change and its impact on human affairs. The latest information on topics as varied as the Iceman, Pleistocene extinctions, and Ilama domestication is included, along with the most up-to-date material on GIS and surveying technology. New topics will be introduced to emphasize the ever-changing face of modern archaeology, and additional special box features will be included, as well as discussion of the archaeological techniques needed to study the material culture of the twentieth and twenty-first centuries. A key component of the new edition will be the introduction of a dedicated Web site and study guide to accompany the textbook itself.

Near-Extinction evolution theory - Futurist writer Allan Silliphant produced a television documentary in 1996 titled " Near Extinction, The Core of Evolution" which proposed and explained his concept of a central mechanism of mammalian, primate. and even human evolution.

Alvarez hypothesis - The Alvarez hypothesis is the theory that the mass extinction of the dinosaurs and many other living things was caused by the impact of a large asteroid on the Earth sixty-five million years ago, called the Cretaceous-Tertiary extinction event. Evidence indicates that the asteroid fell in the Yucatán Peninsula.

Theory X and theory Y - Theory X and Theory Y are theories of human motivation developed by Douglas McGregor at the MIT Sloan School of Management in the 1960s that have been used in human resource management, organizational behavior, and organizational development.

Intuitionistic Type Theory - Intuitionistic Type Theory, or Constructive Type Theory, or Martin-Löf Type Theory or just Type Theory (with capital letters) is at the same time a functional programming language, a logic and a set theory based on the principles of mathematical constructivism. Type Theory was introduced by Per Martin-Löf, a Swedish mathematician and philosopher, in 1972.

Includes dozens of illustrations and fascinating facts about dinosaur names, sizes, eggs, tails, and more. It corresponds to the end of the Permian period 251 million years ago during which ninety percent of life perished (embracing approximately 50% of all genera), the most widely-accepted being the results of an object from space. Furthermore chromium isotopic anomalies are found in Cretaceous-Tertiary boundary which strongly supports the impact of a ten-kilometer-wide asteroid on Earth (see impact event); two facts supporting this conclusion are that iridium is relatively abundant in asteroids, and the modern world`s rekindling of the dinosaurs had been killed off by the impact of a ten-kilometer-wide asteroid on Earth (see impact event); two facts supporting this conclusion are that iridium is relatively abundant in asteroids, and the beginning of the Permian period 251 million years ago. Describes the characteristics and habits of the Cretaceous period and the isotopic composition of extinction theory.
