I want to know the answer to the following question:
What feature of the Birmingham Quran fragments' text make some doubt that it is older than other known versions of the Quran?
All the background I'm provided with is that "Saudi scholar Saud al-Sarhan has expressed doubt over the age of the fragments as they contain dots and chapter separators that are believed to have originated later.". Is that enough to answer the question?
Answer: yes
