  Extinction - Wikipedia, the free encyclopedia
Many of prehistoric extinct species have evolved into new species; for example the extinct Hyracotherium (an ancient horse-like animal) was the ancestor of several extant species including the horse, the zebra and the donkey.
A species may become functionally extinct when only a handful of individuals survive, which are unable to reproduce due to health, age, lack of both sexes (in species that reproduce sexually), or other reasons.
According to a 1998 survey of 400 biologists conducted by New York's American Museum of Natural History, nearly 70 percent of biologists believe that we are currently in the early stages of a human-caused mass extinction, known as the Holocene extinction event.

 Recently Extinct Birds
There is little we can do about those species which are already gone but by practising a philosophy of personal awareness combined with an abhorrence for the manifestations of greed and ignorance we can perhaps play a part in slowing down the destruction of this precious diversity of beauty and life.

 Recently Extinct Animals - Cloning
Many animals went extinct due to loss of their natural habitat, so if no suitable habitat will be available the resurrected species would be condemned to life in zoos.
Another main concern about cloning extinct animals is that cloning might lead people to think of extinction as a temporary state.
Although this is obviously a publicity exercise by the company to clone the first extinct animal, the project could be of useful conservation value if only multiple goats could be cloned to form a viable gene pool.

 Cloning Extinct Animals
The blockbuster hit Jurassic Park, based on the Michael Crichton novel of the same name, introduced the theory that by using genetic material from extinct animals combined with that of amphibians (the only species of vertebrates able to regenerate lost limbs), scientists would be able to bring dinosaurs back to life.
While the egg was accepted by Bessie the cow's immune system, the Gaur calf suffered the same fate as all of the other cloned animals, and it succumbed to illness shortly after being born.
If implanting eggs which were taken from a host animal with the DNA of another animal for the purpose of its acceptance by the host body's immune system produces similar results every time, maybe the implanted embryo's immune system fails to develop as that of a normal fetus.

Readers of Extinct will notice that a quote on the novel's back cover is from Dr. Dean A. Dunn, a notable marine scientist with doctorates in both Oceanography and Paleontology, and a former shipboard scientist for Glomar Challenger expeditions in the western North Atlantic and the Pacific.
In the particular part of the Pacific where the megalodon tooth was found, the sediment is laid down at a rate of approximately four inches per hundred years.
Even given the shorter period of time, the sediment should have built at such a rate as to have buried the tooth hundreds of feet under the ocean floor--not lying exposed on it or only a few inches under the sand for a dredge to scoop up.

It may be that some of these birds are not extinct, only hiding (Fuller shows this has happened before), but most of the birds here are certainly as dead as dodoes.
Although there are some fairly unexceptional exceptions among the ranks of the extinct, not a few of the world's most memorable birds are now among the lost.
That works out to 2000 extinct species but we know that the correct figure is 85, so it simply means that for many years there were no extinctions.

This is not to discourage you in thinking that we will never be able to clone recently extinct animals such as mammoths, but we still need to do plenty of research and develop new techniques before we are likely to be successful.

 Scientific American: When Extinct Isn't
At least 24 species of other presumed or possibly extinct plants, insects and other organisms have been found during natural heritage surveys in North America since 1974, according to Mark Schaefer, president of NatureServe, a nonprofit conservation group based in Arlington, Va. There are examples from elsewhere as well.
With so many "extinct" creatures reappearing, it is reasonable to wonder if the word has lost its meaning--something Ross MacPhee, curator of mammalogy at the American Museum of Natural History, has been outspoken about.
"The word 'extinct' is an absolute term, like pregnant or dead," Fitzpatrick remarks, "so we need to describe the probability of that being true." In cases such as the passenger pigeon, which has not been seen by anybody for nearly a century, "we treat it as formally extinct," he notes.

 CNN.com - Wildlife park to add mammoth attraction - August 21, 2002
The Times of London reports that Japanese scientists are planning to use tissue from the legs and testicles of a dead mammoth to clone the extinct creature and display it at an Ice Age wildlife park in Siberia.
Mammoths became extinct about 10,000 years ago, but using a technique that involves impregnating an Indian elephant -- its closest genetic relative -- with mammoth sperm and then repeating the procedure with its offspring could produce a creature that is 88 percent mammoth in 50 years, the report said.
An alternative technique would involve cloning the mammoth from DNA found in the soft tissue, but although methods of extraction have improved, complete strands of DNA from mammoths are still hard to come by.
