Charles Darwin’s “Survival of the Fittest”


When Charles Darwin created the phrase “survival of the fittest”, he did so before the term “ecosystem” was commonly used within the English vernacular. Darwin originally intended to state that the species or organism which fit in best with its environment, would have the most probable chance of survival. It is a common misconception that Darwin was referring to physical attributes like strength, speed, and fight or flight endurance

World Population Growth


200 years ago, the world had approximately 1,000,000,000 (1 billion) people. Today there are more than 7,000,000,000 (7 billion) people worldwide. By the end of the century, it has been predicted that Earth will have approximately 10,000,000,000 (10 billion) people. The majority, but not all, of the world’s population increase is due to impoverished third world countries as the governments of these nations are not meeting the same standards of industrialized countries in terms of educating their populous regarding sexual activity and birth control as well as affording free or subsidized birth control interventions. It is estimated that the world will not exceed 12,000,000,000 (12 billion) people as many countries, both industrialized and non-industrialized are now declining in their birth rates, due to conscious efforts made by governments to educate the general public in respect to sexual health

The Extinction of Species


130 species go extinct each day. 99% of all life which has ever lived upon Earth, is now extinct. Most species of mammals only survive 1,000,000 (1 million) years before going extinct. Modern human beings have existed for 200,000 years, but the most distant related ancestors of human beings, creatures more apelike than human but still bipedal and using tools, date back 3,000,000 (3 million) years with that particular ancestor being named “Australopithecus afarensis”

Sizes of Life On Earth


Life on Earth varies from the massively large as is the case with trees which reach heights of 100 meters and have a mass of 1000 tonnes, to the incredibly small as is with bacterium which are less than 1,000,000th (1 millionth) of a millimeter with a mass less than 10,000,000,000,000th (10 trillionth) of a gram. These differences span over 22 orders of magnitude in mass
