I feel like nobody who commented here actually read the article. You have people here talking about the way smells are wired to the brain, or some inherent property of smell itself, when the <i>entire article</i> is about two tribal groups that have words for smell in the same way we have words for colour. This shows that having few words for smell is <i>not universal</i> and is likely not due to some hard limitation in the way smell is processed in the brain.
