Yes. We know that. That's how they know that Denisovans have some DNA in common with polynesians. Keep in mind that Denisovans were around BEFORE Neanderthals. We know practically nothing about what they look like because we only know about them from a few small bones.

> sequenced the girl's genome with an accuracy that was once considered impossible with such ancient specimens. The final sequence matched the quality of modern genetic tests on living people.

That is impressive.

> Could they bring her back to life, if so how?

It's scientifically and technically feasible, even easy. Far easier than bringing back the Tasmanian tiger or Woolly mammoth. Politically impossible, the ethics committees would never approve it. The method would start with taking apart the genome from a human cell, making appropriate changes throughout (not a complete change, but all changes that radically affect proteins) and stitching the DNA back together before inserting it into an embryonic stem cell. The result would be implanted in a human uterus just like IVF.
