Passage Summary: Some people think chimps must have a basic form of language because they are our relatives. An anthropologist argues this is a mistake because we didn't evolve from chimps; we just share a common ancestor, and language might have started after that ancestor was long gone.

Conclusion: It does not follow from the close relationship between humans and chimpanzees that chimpanzees possess a version of human language.

Reasoning: Humans and chimpanzees share a common ancestor rather than a direct lineage, and language could have evolved in humans after the two species diverged.

Analysis: The main conclusion is the anthropologist's rebuttal of the 'many people think' position. The author uses the transition 'but it simply does not follow' to signal their primary claim. The rest of the stimulus is dedicated to explaining the evolutionary history (common ancestry vs. direct descent) to support why the popular reasoning is flawed. When identifying the conclusion here, focus on the statement that rejects the necessity of chimpanzees having language.
