“The Rheobatrachus silus frog has been extinct since 1983. This unusual Australian creature was known for swallowing its eggs and then releasing the young from its mouth. That’s way too awesome to just let the animal be resigned to the biological history books.

Australian researchers have spent five years conducting experiments using somatic-cell nuclear transfer, a technique for creating a cloned embryo. Appropriately enough, it’s called the Lazarus Project. The scientists took donor eggs from a related frog and replaced the nuclei with dead nuclei from the extinct frog. Some of the eggs then began to grow.” (CNET).
