Countless thousands of species went extinct before man every showed up on earth. The difference is: Since we weren't here to screw anything up, it was a natural part of nature. Now even today, the great majority of species facing extinction are there due to no fault of man's - nature is continually extincting species and replacing them with new ones, man or not. But some species are definitely near the brink because of man, and those are the ones we are working hardest to save. For if they become extinct, it won't be natures doing - it will be our fault.

What are all the extinct animals names that were from California?

The best way I know to answer this question is by going by the now extinct animals found in the La Brea Tar Pits. Therefore, this list may be considered incomplete. The American Mastadon The Saber-toothed Cats Yesterday's Camel The Dire Wolf The Giant Ground Sloth The Western Horse Some of these animals are not truly extinct, as some animals such as the camel and the horse migrated to other continents and were subsequently re-introduced into the U.S. within recent history. There are/were also much smaller animals and birds that are not truly extinct in the world, but no longer exist in California, like the skunk, ground squirrels, coyote, etc.
