Answer #1

Answer 39:

Neanderthal DNA has been found in the genome of humans who live out of Africa. Humans originated in Africa, and migrated to other parts of the world, but Neanderthals lived only in Eurasia. Presence of Neanderthal DNA in humans suggest that interbreeding occured between humans and other less developed forms. This supports the partial replacement theory of human migration and evolution. The correct choice should be:

(c) Partial replacement model.

Answer 40:

Gene flow and natural selection in archaic humans led to development of modern humans independently in different regions of the world, according to theregional continuity model. The correct choice should be:

(b) regional continuity model.

Background: Darwinism Today the theory of evolution is a well-supported, unifying principle in biology, which explains how life on earth began and developed. The scientific evidence overwhelmingly supports the idea that all living things share a common ancestry. Charles Darwin, a British naturalist, is the person most remembered for his contribution to how the process of evolution works. He wrote a book, published over 150 years ago, called On the Origin of Species, which was very controversial at the time....
