Correct Answer :

Option B

an early human species

Solution :

The correct option is an early human species.


Step-by-step explanation:


1. What are Denisovans?
Denisovans are an extinct species or subspecies of archaic humans that lived in Asia during the Lower and Middle Paleolithic eras.


2. Discovery and Origin:
The Denisovans were identified in 2010 when scientists sequenced the genome of a fossilized bone fragment (a pinky bone) discovered in 2008 in Denisova Cave, located in the Altai Mountains of Siberia, Russia.


3. Relation to Modern Humans and Neanderthals:
Genetic evidence shows that Denisovans shared a common ancestor with Neanderthals and interbred with ancient modern human ancestors (Homo sapiens). Genetic traces of Denisovan DNA are present in several modern human populations today, particularly among Indigenous Australians, Papuans, and some Asian populations.


4. Conclusion:
Therefore, in media reports, the term "Denisovan" is frequently mentioned when discussing early human evolutionary history, anthropology, and archaic human genetics.
