Resurrecting Extinct Species: The Limitations of DNA Extraction
27:40 - 34:11 (06:31)
DNA degrades over time, making it difficult to extract useful genetic material from extinct species that have been dead for over 7 million years. However, scientists are exploring the possibility of genetically reconstructing a genome using broken genetic material found in museum specimens such as hair samples, fur, and bone.

Scientists use cloning to try and bring back the extinct Pyrenean Ibex using frozen cells collected from the last surviving female of the species, but the cloned animal dies after just seven minutes due to lung deformities.
