An estimated 99.9% of species that have ever lived are now extinct and we don't even have evidence of most of those.
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.
Animals that are extinct from the earth are animals that used to live on the earth but are all dead now. Endangered animals are almost extinct.
The difference is an endangered animals only has about a couple thousand of its kind left. Threatened animals still has a fair amount left. And extinct animals are all gone.
If we don't help them then they will be gone forever and are impossible to get back. Such as the dodo, the mammoth and many others. Scientists are trying to bring back the mammoth by extracting the DNA from a baby one found in Serbia. Many species of animals will be extinct before we even discover them. They just found a new species of ant in Canada 5 days ago. ======================================================== Extinct animals can't be saved. Actually, there's the possibility that some extinct species may be "brought back" by cloning them using tissue or DNA. Not all extinct animal left behind viable DNA. This may be possible with certain animals, but probably not all.
Extinction. When a species fails to adapt, it dies out.
Extinct is already dead and Endangered is there is less of them left in the world meaning we should try to save them !!
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.
Extinct is when an animal or plant doesn't exist any longer on earth.
If an animal becomes extinct, there will be no more of that species left like the Dodo. No more are left as they are extinct.
People should help protect extinct species because they are for all our Natural Resources
Animals that are extinct from the earth are animals that used to live on the earth but are all dead now. Endangered animals are almost extinct.
species can become extinct when people kill all the animals or their habitat is completely destroyed and they can't find food, and other animals kill and eat that species. a third way is that all the animals get a disease that kills the entire species
Extinct (Extinction)
Fossil evidence of the same species found on multiple continents. Matching geological formations across continents, such as mountain ranges. Similar rock formations and ages of rocks on different continents. Paleoclimatic evidence, like glacial deposits in areas that are now far from the poles. Fit of continental shelf margins, where coastlines align when continents are pieced together.
It is estimated that 99% of all animals that have ever lived are now extinct.
The difference is an endangered animals only has about a couple thousand of its kind left. Threatened animals still has a fair amount left. And extinct animals are all gone.
just about every one. 90% of all creatures that have lived on earth are extinct.
