Reading Comprehension: Detail Questions

According to the passage, the hybrid morphological traits identified in Neanderthal skeletons were considered

Incorrect.

[[snippet]]

The third sentence of the first passage assumes that Neanderthals and humans were distinct species. Without assuming this, one could not talk about hybrid (=mixed) traits. However, an assumption is not the same as a proof. The passage does not state that the hybrid morphological traits prove that Neanderthals and humans were distinct species. 

Incorrect.

[[snippet]]

The passage states that some scientists thought the skeleton-based findings were inconclusive evidence in respect to the hypothesis that the two species had mated. The passage does not refer at all to high genetic mutability (=ability / tendency to change/mutate).

Incorrect.

[[snippet]]

The passage does not develop an argument for continued support for research in skeleton-based findings. Quite the contrary - the new findings in DNA are presented as an approach that veers away from the conclusions reached by skeleton-based findings.

Incorrect.

[[snippet]]

The passage does not state that the skeleton findings from ancient Neanderthals exhibited expression of shared genes. Shared genes are mentioned in the second sentence of the first paragraph, but these are genes shared by ancient Neanderthals and contemporary humans.

Well done!

[[snippet]]

The passage states that some researchers once thought that the mixed morphological traits lent support to the theory that humans and Neanderthals must have mated (=interbred) in the evolutionary past., while others thought the evidence to be inconclusive (=indefinite).

proof that Neanderthals and humans were previously two anatomically distinct species
inconclusive evidence of high genetic mutability within one species
an important argument for continued research on skeleton-based findings
to exhibit expressed elements of the shared human-Neanderthal genome
as possible, albeit indefinite, support for the hypothesis that humans and Neanderthals had once interbred
