Mass extinction
Extinction is a continual product of natural selection. since the dawn of competition spawned by the first meiosis event , natural selection has altered all life on earth, precariously engaging in life experiments some that work and some that don’t. Those experiments that do not work are those who have so far been extinct, and in fact 99%(Kiernan 1996:574) of all species that have ever engaged in the life battle have met their fate and are now extinct. why does this happen? what causes a species to be extinct? and how? if we can-- prevent it. To answer these questions we must first define what extinction means, what types are there and why do they occur. Extinction; some people define, as the disappearance of a plant or animal from the wild. Meaning that creatures surviving only in zoos or natural reserves could also be considered extinct. Other people use the terms “regional extinction” and “local extinction” to refer to the elimination of a creature from a specific geog!raphical area but not from the whole planet(Kiernan 1996: 574). These types of extinctions are rather common and are usually caused by human intervention in the form of over hunting, introduced competitors and destruction of habitat. Anoth
