Today, as scientists mull using genetics to bring back everything from the long-gone woolly mammoth to the more recently smote heath hen, some have raised an intriguing question: If you raise an animal from extinction, is it really the same animal as the one that went extinct?

The old-timey Republican of yore smiled through a photo op for the unveiling of a new sculpture of an American bison, a species that almost went extinct when, among other things, travelers on the railroad we had gathered to glorify shot buffalo from the windows of passing trains.

In their study, Dr. Bennett and his collaborators tried to approximate the costs of re-establishing and maintaining 16 species that went extinct in the last millennium, including the Lord Howe pigeon and Eastern rat-kangaroo from Australia, and the laughing owl and Waitomo frog from New Zealand.

Before the discovery of Halszkaraptor, the entire idea of small, waterbird-like theropods hunting down fish was some mix of inconceivable or speculative fiction (Halszkaraptor is eerily similar to the pouch in Dougal Dixon's The New Dinosaurs, which imagines an alternate timeline in which the non-avian dinosaurs never went extinct).

No one's been able to bring back long-dead animals (including woolly mammoths) yet, though if scientists could snag some DNA before the species goes extinct, it seems possible: the Pyrenean Ibex, a Spanish wild goat that went extinct in 103, was successfully re-created using a surrogate goat mother.

Standing nearly 10 feet tall and weighing up to 1,000 pounds — or so researchers believed — this flightless cousin of the ostrich went extinct in the 17th century, thanks in part to humans stealing their massive eggs, either to feed their own families or to repurpose them as giant rum flasks.

This eventually led her to research the red-shanked douc langur, an endangered primate native to a small area of Vietnam near Danang City, and to learn more about the passenger pigeon, which went extinct when the last of its species, named Martha, died in the Cincinnati Zoo on September 1, 1914.

We used to the think that there was a linear trajectory from our fossil ancestors to contemporary modern humans, but the more fossils that are discovered, the more evidence we have to suggest that there was not just an ancestral branch or tree, but more of an ancestral bush of fossil species which went off in various directions and then for whatever reason—we still don't know—went extinct.
