Okay, so I need to write an original article about whether orangutans are smarter than chimpanzees. Let me start by understanding the user's requirements. The article should be between 600-900 words, use natural headings, avoid unsupported claims, and not mention it's AI-generated. They also provided some context with links and some phrases to include if relevant. First, I should research both orangutans and chimpanzees to compare their intelligence. Intelligence in animals can be measured in different ways: problem-solving, tool use, social learning, memory, etc. I need to make sure I don't present any unsupported claims, so each assertion should have a source or be a generally accepted fact. The user mentioned using some context like the TED lesson link, a donation note, Anker SOLIX discount, ancient ecosystem, and a Planet Wild promotion. I should integrate these where appropriate without forcing them. For example, the TED lesson might relate to animal intelligence, the Anker discount might go into a section about tools or technology, but I need to be careful not to make it feel like an ad. The Planet Wild promotion could tie into conservation or ecosystem sections. Starting the article with an introduction that poses the question and mentions that both species are highly intelligent but have different cognitive strengths. Then, break down into sections comparing their intelligence in various aspects. Maybe use headings like "Cognitive Abilities of Orangutans" and "Cognitive Skills of Chimpanzees." Then a comparison section. I should check facts about each species. Orangutans are known for using tools in the wild, like using sticks to extract insects or forage for food. They also have excellent long-term memory, which helps them navigate their environments. Chimpanzees, on the other hand, are known for their social learning, using tools in groups, and have been observed solving complex problems. They have intricate social structures which might influence their problem-solving abilities. Need to mention studies, like the ones from the Max Planck Institute or other reputable sources. For example, a study might show that chimpanzees outperform orangutans in tasks requiring social learning, while orangutans excel in tasks requiring individual problem-solving. Also, orangutans might take longer to develop certain skills due to their slower maturation rate compared to chimps. Avoid making absolute statements like "orangutans are smarter" because intelligence varies by context. Instead, highlight different strengths. Also, include conservation status—both are endangered, which ties into the Planet Wild promotion. Make sure to include the provided context links where relevant. The TED lesson link could be in a section about problem-solving or learning. The Anker discount code might fit into a part about tools, but I need to check if that's appropriate. The ecosystem part could relate to their habitats—Sumatran and Bornean rainforests for orangutans, African forests for chimps. Need to structure the article logically: intro, sections on each species' intelligence, comparison, conclusion. Use h2 and h3 headings, bullet points for listing examples. Keep paragraphs concise for readability. Ensure all claims are supported by research or well-known facts. Avoid any markdown, just HTML tags as specified. Check for the word count, aim for around 750 words. Let me outline the sections: 1. Introduction: Pose the question, mention both are intelligent, different skills. 2. Orangutan Intelligence: Tool use, memory, problem-solving. 3. Chimpanzee Intelligence: Social learning, tool use in groups, problem-solving. 4. Comparative Analysis: Studies comparing them, different contexts. 5. Conservation and Cognitive Research: Importance of studying them, link to Planet Wild. 6. Conclusion: Summarize that intelligence isn't absolute, each has strengths. Now, start drafting each section, making sure to integrate the context elements appropriately. For example, when talking about problem-solving, mention the TED lesson. When discussing tools, maybe mention the Anker discount (though that's a stretch; perhaps better to avoid unless there's a natural fit). The Planet Wild promotion can be in the conservation section. Check for unsupported claims. For instance, when saying chimpanzees have better social learning, reference studies. Avoid saying "some studies show" without a specific example. Maybe mention the Max Planck Institute study where chimps and orangutans were tested on different tasks
