Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete. Even if all of them did fossilize many would be too hard dig for many of them. And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered.

Human influence on species evolution Greed is a capital sin‚ but many businessmen do not care about that in order to raise their profit.

Hey‚ have you ever wondered where dogs came from? Dogs species came from their ancestors called the grey wolf. Our nation is filled with different breeds. So they breed their dogs with other breeds so they get farther away from the grey wolves. In "The Amazing History of Dogs" text it says that the scientists still do not even know how the wolves changed over time to become dogs and became pets for us to breed and make new species of dogs.

The story "The Half-Skinned Steer" by Annie Proulx could be classified in the Return to the womb arch-type.

The one major event that leads him back home is the death of his brother Rollo. Mero had left the country out by Cheyenne‚ Wyoming to go and live in New York City. Over that time he had grown to become a fairly rich man
