Answer 1

Svante Paabo: Poineered sequencing of Ancient DNA

(Svante Paabo, a swedish geneticist extensively worked on Neandethal genome and was the first to successfully sequence the Nandethal mitochondrial DNA)

Africa-Middle east land brdge: Migration Route which favoured the intermixing of different human races

Freckles: Vitamin D from concentrated melanin (For this i am not sure)

These represent the brown/reddish harmless spots on the skin due to overproduction of melanin on exposure to sun particularly in people with fair complexion.

Percent Neanderthal DNA in Africans: 0 %

It has been found that the Africans have no or little (upto 0.3%) of neanderthal DNA as they have not migrated or invaded any other area oustide Africa in the evolutionary context.

Neanderthal Contribution to human evolution: Keratin

Neanderthals have contributed the genes for keratin to modern humans which provided morphological adaptation in skin and hair to adapt to non-african environments.
