Through the science of archiology. They dig up the bones and other remains of animals, reassemble them kinda like a 3-D jigsaw puzzle, and study the skeletal sructure of the animal. This gives a lot of general information. They then study individual parts of the skeleton to learn some more detailed things. The teeth for instance will tell if they were an herbavore (with flat grinding teeth), a carnavor (with sharp cutting teeth), or an omnivor, with a combination of types of teeth (like humans have)
Animals are killed from deforestation and scientists believe that many species of animals and plants become extinct everyday in the amazon rain forest.
Because people kept finding their fossilized bones as well as complete animals frozen in the permafrost of Siberia. There aren't any of those animals living now so they must be extinct.
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.
I have heard rumors that scientists have discovered a way of doing it but remember it was a rumor! but l think it's true!!^^ Scientists have begun attempting to bring back extinct animals by making a clone using DNA found in fossils. I do not know if they have succeeded
If all animals go extinct there will be no need for food!
They don't, they guess.
they learn behavioral patterns of the animals.
Scientists learn about plants that are extinct by studying their fossils. These fossils will often preserve a plant's remains very well.
scientists are trying to save the endangered species , by just making the people aware of the animals. scientists can save the endangered animals only if they come to know that how to make an animal from it's DNA. if this happens only if it can,,, the extinct species like the dodo can become alive again.
noone is sure even scientists but there's alot because dinosaurs + existing animals + extinct animals = alottt
Scientists are trying to. there trying to bring the wolly mammoth
Fossils are the only way to learn which animals are extinct or have changed over time. We can look at animals that exist today and speculate concerning on the appearance of a common ancestor. We frequently have to change our opinion when we find a fossil.
It is generally accepted that animals from the prehistoric time became extinct to a massive shift in climate. Scientists believe that a meteor struck the earth and the aftermath caused the extinction of many plants and animals.

They cant yet but there's no saying that later on in the future they will be able to

Scientifics find the dna from the animasl and they do some test and vertyfity which ones are endagered
