Scientists Actually Brought These Extinct Animals Back

Scientists have already gotten shockingly close to bringing extinct animals back to life — and in one case, scientists actually cloned an extinct animal and watched it be born alive. In this video, we’re ranking 6 extinct animals scientists have attempted to bring back through de-extinction, cloning, selective breeding, ancient DNA, embryos, and genetic engineering. We’ll look at the aurochs, an extinct wild ancestor of modern cattle that researchers are trying to recreate through selective breeding; the quagga, whose extinct appearance has been recreated using specially selected plains zebras; and Yuka the woolly mammoth, whose 28,000-year-old preserved cells were used in experiments with living mouse eggs. Then things get even crazier. Scientists working on the gastric-brooding frog created developing embryos using genetic material from the extinct species. Colossal Biosciences has also created the living animals associated with its dire wolf de-extinction project, including Romulus, Remus, and Khaleesi. But the craziest story happened with the Pyrenean ibex, also known as the bucardo. Scientists used preserved cells from the final known female, Celia, to create a cloned embryo. In 2003, that embryo developed into a Pyrenean ibex that was actually born alive, making it one of the most unbelievable moments in the history of cloning and de-extinction. From woolly mammoths and dire wolves to extinct frogs, zebras, cattle, and the first extinct animal cloned back into existence, these experiments show just how far scientists have already pushed the science of bringing extinct species back to life. Could we eventually see a living woolly mammoth, dodo, thylacine, or other extinct animal in the future? And if scientists can bring extinct animals back… should they? 🦖 Subscribe for more videos about dinosaurs, extinct animals, prehistoric creatures, fossils, de-extinction, ancient DNA, rare animals, cloning, and incredible discoveries from prehistoric Earth. #ExtinctAnimals #DeExtinction #DireWolf
