In George Church's book Regenesis, he recounts the interesting story of resurrecting the Pyrenean Ibex by somatic cell nuclear transfer and surrogate pregnancy in a closely related species. The source article is a great read [0]. The animal that resulted died of lung complications shortly after birth, but apparently veterinarians indicated that these complications were totally within the norm of ibex ontogeny, and probably not a failing of the underlying cell biology. So, for just a few minutes, an extinct species was brought back to life. [0] -- https://www.ncbi.nlm.nih.gov/pubmed/19167744 https://www.ncbi.nlm.nih.gov/pubmed/19167744
