Final answer:
The discovery of the Denisovan remains in the Denisova cave allowed paleoanthropologists to reconstruct their genome and gain insights into their relationship with Neanderthals and modern humans.
Step-by-step explanation:
The discovery of a finger bone and two teeth in the Denisova cave has allowed paleoanthropologists to reconstruct the genome of an archaic human species known as the Denisovans. Genetic analysis of the DNA from these remains revealed that the Denisovans were closely related to Neanderthals and interbred with both Neanderthals and modern humans. The study of their genetic material has provided valuable insights into the evolutionary history of humanity.
