can this bring the extinct dodo birds back out of extinction

I am not sure about the dodo, but a previous answer had the mammoth comment at least partially right. DNA decays & breaks down just like the rest of a body after death, so any sample pulled from a dodo (like a stuffed one in a museum) would be pretty busted up. That being said, animals with close living relatives (like the mammoth or the North American lion, or many other large Pleistocene mammals) do have a possibility of resurrection.

Some scientists r trying to splice (combine) mammoth DNA with African elephant DNA & implant the ''clone'' into a captive elephant. These two species r similar enough that an elephant female could theoretically give birth to a mammoth.

Even if this works, it will unfortunately not bring these species truly out of extinction - their habitats r gone, & we can barely keep alive what species r left. It would most likely be a tourist attraction or a scientific study. Besides, animals learn a lot from their parents, & without parents of the same species, the ''new'' dodos or mammoths would never be what the once were.

sounds like Jurassic park if you ask me

a few months ago somehow they recreated a living mammoth, so i guess its posible

If that worked nothing would be extinct, now would it?
