It is estimated that out of all species that have ever lived, almost 99.9% of all species have gone extinct. No species will ever live forever, they will go extinct one time or another no matter what.
The species is said to be extinct.
False. Animals were made the same day as man!!!!! The above is true if you believe exclusively in creationism. Science says that all the species of animals that live on earth today make up less than one tenth of one percent (0.1%) of all the animals that have ever existed. So to answer your question: yes, many species became extinct before mankind altered the earth.
Seeing that the earth has an estimated less than 1% of animals that have ever existed currently living on it, it is an extremely hard question to answer.
You can't. If a species is extinct, that means that no organism in that species is alive. It is gone forever.
