There have been many extinct animals in the last 100 years. But scientists are considering the possibility of bringing some of these animals back through a process called “de-extinction.” In choosing extinct animals to bring back, scientists consider certain factors such as their ecological functions and the availability of tissues with quality DNA samples. Some of these animals have already been identified. If successful, this could be a huge win for not only extinct animals but animals that are endangered as well! These are 25 extinct animals that scientists want to bring back.
This ground-dwelling frog was native to Queensland, Australia and became extinct sometime in the mid 1980’s. However, scientists at the University of Newcastle and University of New South Wales announced in March of 2013 that this frog would be part of the “Lazarus project”, a cloning attempt to resurrect the species.

Caribbean Monk Seal
Last seen in 1952, the Caribbean Monk seal was brought to extinction due to excessive hunting for its oil and the overfishing of its main food source. Though unconfirmed sightings from local fishermen in Haiti and Jamaica exist, there is no conclusive evidence that this seal is still in existence.

The woolly mammoth was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene. The appearance and behavior of this species are among the best studied of any prehistoric animal thanks to the discovery of frozen carcasses in Siberia and Alaska, as well as skeletons, teeth, stomach contents, dung, and depictions of life in prehistoric cave paintings.
