I want to know the answer to the following question:
One theory posits that Samoans originated from what people during the Lapita expansion period?
All the background I'm provided with is that "Scientific research is ongoing, although a number of different theories exist; including one proposing that the Samoans originated from Austronesian predecessors during the terminal eastward Lapita expansion period from Southeast Asia and Melanesia between 2,500 and 1,500 BCE.". Is that enough to answer the question?
Answer: yes
