The Scenario Presented in Jean Bruller's (Vercours') Novel Is Relevant

The scenario presented in Jean Bruller's (Vercours') novel is relevant to actual paleoanthropology. Something like it could have happened because:

A) chimp DNA and human DNA have been shown to be 99% identical
B) the production of living extinct creatures from the DNA present in their fossil bones will probably happen in the next century
C) there is increasing evidence that presumed extinct hominins are actually alive in the most remote parts of New Guinea
D) anatomically modern humans and Neandertals coexisted, and the Neandertals became extinct relatively recently
