I want to know the answer to the following question:
When was the emergence of the Greek spoken dialect believed to have started ?
All the background I'm provided with is that "Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age.". Is that enough to answer the question?
Answer: yes
