Nuclear DNA and Human Population

Context:

In a study of human populations of the Pleistocene era, nuclear DNA is of main importance. We can extract those valuable DNAs from bones and teeth of the primitive Pleistocene hominin. But they are very difficult to find in archeological sites. On the other hand, mitochondrial DNA which is found more often gives less data about populations.

Let's deep dive:

The motive of study-

To uncover more data on west-European and south-Siberian Neanderthal populations from sediment samples found in caves that date back to the Pleistocene era.


Sites-

  • Chagyrskaya and Denisova Caves which are previously studied upon and another site of Galería de las Estatuas in northern Spain.

  • The Chagyrskaya cave has yielded two high-coverage genomes of Neanderthal species.

  • The cave of Denisova has yielded one genome of Denisovan species.

  • The site of Galería de las Estatuas remains unexplored until the study is found to home Neanderthals for th
