Question 1

Modern DNA

Answer 1

Intact and well-preserved DNA, available in abundance, obtained non-invasively.

Question 2

Degradation (DNA)

Answer 2

The breakdown of DNA over time, making it difficult to work with.

Question 3

Archaic Introgression

Answer 3

Gene flow from ancient hominins like Neanderthals and Denisovans into modern humans.

Question 4

Adaptive Introgression

Answer 4

Transfer of beneficial genes from archaic humans to modern humans, aiding adaptation.

Question 5

Patrilocal Organization

Answer 5

Social structure where males remain in their birthplace while females migrate.

Question 6

Paleoproteomics

Answer 6

Study of ancient proteins surviving in archaeological or paleontological remains.

Question 7

Gene Flow

Answer 7

Transfer of genetic material between populations or species.

Question 8

Biological Species Concept (BSC)

Answer 8

Definition of species as groups of interbreeding populations.

Question 9

Fragmentary Fossil Record

Answer 9

Incomplete record of fossils due to preservation issues.

Question 10

Archaic Admixture

Answer 10

Mixing of genes between modern humans and archaic humans like Neanderthals and Denisovans.

Question 11

EPAS1 Gene

Answer 11

Gene associated with high-altitude adaptation, inherited from Denisovans.

Question 12

Introgressed Haplotype

Answer 12

A set of genetic variants inherited from archaic humans.
