Please answer the following question: I know that the answer to the question "What did Gautama Buddha teach other than Three marks of existence, the Five Aggregates, karma and rebirth, the Four Noble Truths, the Noble Eightfold Path, and nirvana?" is in "Pre-sectarian Buddhism is the earliest phase of Buddhism, recognized by nearly all scholars. Its main scriptures are the Vinaya Pitaka and the four principal Nikayas or Agamas. Certain basic teachings appear in many places throughout the early texts, so most scholars conclude that Gautama Buddha must have taught something similar to the Three marks of existence, the Five Aggregates, dependent origination, karma and rebirth, the Four Noble Truths, the Noble Eightfold Path, and nirvana. Some scholars disagree, and have proposed many other theories.". Can you tell me what it is?
Answer:
dependent origination
