Its similarity to those of modern humans was seen as evidence by some scientists that Neanderthals possessed a modern vocal tract and were therefore capable of fully modern speech.

Hunting is not the only threat that would face recovered species. De-extinction advocates are pondering these questions, and most believe they need to be resolved before any major project moves forward. De-extinction is about creating populations of healthy, genetically vibrant animals that can be released into the wild where theyll be able to breed naturally and contribute positively to the environment. Dig up a fossil today, and any dino-DNA within would have long since fallen apart. Bringing back the extinct Megalodon may be impossible.
