Böcker av George Mcghee

300 million years ago, dog-sized scorpions and millipedes walked the earth and tropical rainforests towered into the sky. George R. McGhee Jr. explores that ancient world, explaining its origins, its downfall in the end-Permian mass extinction, and its legacies, to offer insight into past and present extinction events and climate change.

Based on two decades of research, this book reviews the many theories presented to explain this extinction on Earth, particularly covering the idea that it was triggered by the impact of extraterrestrial objects. It also provides a review of a wealth of different pieces of geographical evidence.

This text provides background and steps in defining geometric parameters for organic form in order to generate a spectrum of other possible forms. It also addresses simulation of actual processes of morphogenesis, aiming to attain a nuanced comprehension of how evolutionary processes work.

It describes the inception of the Truman Doctrine to rearm and strengthen Greece and Turkey in the face of British withdrawal, the unsuccessful efforts made by the United States and Britain to establish a Middle East command or defense organisation, and the successful U.S. efforts to get Turkey into NATO, which blocked Soviet entry.
