A previously extinct or lost species can be "revived" or recreated through various methods such as cloning, breeding, genome editing, thawing, and seed germination in plants.
Endemic to the Pyrenees and Cantabrian Mountains, this ibex was driven to extinction by the year 2000 due to competition with livestock and introduced wild ungulates and following the death of Celia, the endling of the subspecies.
Several attempts were made to clone the Pyrenean ibex, and one individual was born to a domestic goat mother in 2003.

[9][10] The Rastreador Brasilerio (Brazilian Tracker) is a dog breed that was bred in the 1950s to aid in hunting jaguars and wild pigs in Brazil.
In the early 2000s, a group named Grupo de Apoio ao Resgate do Rastreador Brasileiro (Brazilian Tracker Rescue Support Group) dedicated to reviving the breed and having it relisted by Confederação Brasileira de Cinofilia located dogs in Brazil that had genetics of the extinct breed to recreate a purebred.
