#3 – Moa
Image Source: Wikimedia CommonsThe Moa is a giant flightless bird that is similar to emus and ostriches but without the wings. Scientists assume that there is a great possibility to bring this bird back to our world. Moas were hunted cruelly to extinction 600 years ago, but their eggs and feathers can still be discovered. So the operation to clone moa has already been started since the DNA can be extracted from their newly discovered eggshells.
