14 extinct animals that could be resurrected

Look at the ruins of this fossil of the ancient creatures, you may believe that you are seeing a huge bear. In fact, these rostral animals are sloths and are closely related to the sleeping contemporary three-legged sloth. Because they have recently become extinct they have become good candidates for resurrection - a huge terrestrial sloth may have crossed the earth at the dawn of 8,000 years ago human civilization.

In contrast, relatives of the only surviving lazy land are not important, so it is impossible to find a surrogate mother. However, one day, the fetus may occur in the artificial uterus.

Beth Shapiro, an ancient DNA expert and biologist at the University of California at Santa Cruz, says, "The resurgence of endangered animals is" exciting and irritated. " What is exciting is that partly because of the unprecedented opportunity to understand life and promote protection, that part is the moral dilemma. In a recently published book "How to Clone Mammoth: Extinction Science" Shapiro provides her based on her rich experience in ancient DNA research, from mammoths and bisons to dodos and passenger doves. Let's start with the necessary steps and questions. The answer before the seed's resurgence may become a reality. In a recent interview, we discussed the practicality of extinction and the simple aspects of gene repair.

Extinction, also known as resurgence biology, restores the process of extinction or extinct species. Once considered a fantasy concept, progress in selective breeding, genetics and reproductive cloning increased the possibility of extinct species revival. The key to these advances was developed in the 1990's called somatic cell nuclear transfer (SCNT) and was used for the production of the first mammalian clone, Dolly the Sheep (born in 1996, died in 2003) .

Extinction may change this situation. Last Friday, geneticists, environmentalists, journalists and other groups met in Washington, DC and discussed the resurgence of extinct species, including mammoth. Although extinction sounds like a science fiction novel, it is rooted in a very realistic protection issue. Due to the sequencing of the mammoth genome and the latest advances in biotechnology, the question of whether to clone endangered species such as mastodon, dodos, shasta sloths is becoming a problem rapidly. The latter is not simple, it involves integrating many frontier fields, but I would like to focus on the former.
