Regenerating extinct animals

The scientific community is hoping, with the Lazarus project, many extinct animals can be reborn for research. This process is more complicated than live animal cloning, but many scientists believe that humans have the ability and responsibility to repair the damage caused to the planet, leading to the death of countless animals.

Frogs hatch with stomach and Pyrenean Ibex mountain

In Australia, scientists are undertaking the regeneration of a frog hatched with stomach in the south of the country, which was certified extinct in 1983. The frog swallowed the fertilized egg and gave birth to a baby. The last female frog of this species died in 1983. Fortunately, the frog's cell samples were frozen and scientists are using a technique called somatic cell nuclear transfer to test regeneration. them.

Researchers at the University of New South Wales have removed the nucleus in the eggs of a living frog that has a close relationship with extinct species, and replaced with extinct frogs' cells. In the spring, these eggs have reached their early embryonic stage. The Daily Mail page quoted Professor Mike Archer of Lazarus project: "We have recovered dead cells into living cells and regenerated the genomes of extinct frogs."

Four years ago, Spanish researchers recreated a mountain goat belonging to the Pyrenean Ibex (extinct since 2000) from another goat. Unfortunately, the animal died shortly after birth. Scientists have carried out similar work with extinct doves in 1914, California seals, Carolina macaws and Tasmanian tigers. Sooam Biotechnology Research Organization (South Korea) has embarked on a project to revitalize fine-haired mammoths.
