Cuban red macaw (late 1800s)An interesting list, but I have some quibbles. We have enough DNA from all of these animals to reconstruct their genomes, but that is not enough to create a live organism. You also need an egg, or an egg cell and a womb. In the case of woolly mammoths, people assume that an elephant egg cell would work, and that an African elephant could carry a woolly mammoth fetus to term. But a giant ground sloth? A newborn baby ground sloth was probably about as big as a modern tree sloth adult, so what sort of animal would carry the giant fetus in her womb? And since there are no living marsupial predators, what would give birth to a Tasmanian tiger?
Woolly Mammoth (3,700 years ago)
Giant ground sloth (11,000 years ago)
New Zealand Giant Moa (1400s)
Tasmanian tiger (1930s)
Saber-toothed cat (12,000 years ago)
Passenger pigeon (1914)
Dodo (late 1600s)
Cuban macaw DNA could presumably be inserted in the egg cell of another Macaw species, which would then make an egg for it and brood it. But a Dodo?
