Answer
De-extinction, also known as resurrection biology or species revivalism, is the process of generating an organism that either resembles or is an exact genetic copy of an extinct species4. This process aims to reverse plant and animal extinctions by creating new versions of previously lost species1. There are several methods to carry out de-extinction, including back-breeding, cloning, and genome editing14.
  1. Back-breeding: This method uses the principles of selective breeding to resurrect diluted or lost animal traits. For centuries, scientists have been using this process to increase the presence of specific traits within a population. However, back-breeding has limitations as a de-extinction approach1.
  2. Cloning: This is the most widely proposed method for de-extinction. Cloning involves growing tissue cells in a lab and then transferring them into a donor egg that's had its nucleus removed. The egg then begins to divide, leading to the formation of an embryo. The embryo is then transplanted into the uterus of a surrogate mother, which in the case of de-extinction is a species closely related to the extinct species13.
  3. Genome editing: This method involves the use of advanced genetic technologies to modify the DNA of a closely related species to resemble that of the extinct species4.
De-extinction has sparked a vigorous debate on its ethics and potential impacts on ecosystems. Some argue that it could help restore ecosystems and increase species diversity6. However, others caution that it could divert resources from preserving endangered species and their habitats310. There are also concerns about the potential for de-extinct species to bring back ancient diseases, disrupt current ecosystems, or fail to adapt to modern environments1114. Despite these concerns, de-extinction has helped fuel important progress in science, particularly in developmental biology and genetics. It has also generated interest in endangered species, with many of the tools of de-extinction also being applicable to the conservation of endangered species6.
