The struggle for life on earth. Mass Extinction - Definition. A significant proportion of species become extinct (between 30% and 95%) . The extinctions operate across a wide range of environments and . Overview. Extinctions are as important in the history of life as are the evolution of new species. Explaining extinctions is just as challenging a scientific question as explaining the evolution of new species. The Sixth Mass Extinction. Essential Questions. What is extinction?. Which species have become extinct in modern times? . What are the characteristics of past mass extinctions? . How do modern extinction rates compare with natural (background) rates?. 1) Geological Time Scale. 2) Major Episodes in History of Life. 3) Extinctions and Radiations. Today. ’. s OUTLINE:. Geology plays an Important role in Evolutionary Thinking. Patterns of extinctions and evolutionary change in the fossil record were among the main influences on. Important Terms.

Global eradication of smallpox in 1977 and discovery of antibiotics led to optimism and complacency that infectious diseases as public health problems could be eradicated or eliminated. Zoonoses. .

Extinction . When an organism is classed as extinct there are no living members of that species left. Extinction is a natural process where organisms that are less suited to an environment die out. Throughout the history of earth there have been several mass extinction events .
