De-extinction
open-in-new
<p>De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an <a href="/facts/Organism/j8JkL09u">organism</a> that either resembles or is an <a href="/facts/Extinction/24p5NP2q">extinct</a> <a href="/facts/Organism/j8JkL09u">organism</a>. There are several ways to carry out the process of de-extinction. <a href="/facts/Cloning/Vb6SM4c7">Cloning</a> is the most widely proposed method, although genome editing and <a href="/facts/Selective_breeding/CAkkM2UG">selective breeding</a> have also been considered. Similar techniques have been applied to certain <a href="/facts/Endangered_species/L7cIweSW">endangered species</a>, in hopes to boost their <a href="/facts/Genetic_diversity/GIymbUr8">genetic diversity</a>. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues. </p>
