Is Iran an Arab country

Answer 1

Whether the question is about genetics or culture, the answers are the same.

Genetics

All the genetic researches done in the 20th and 21st century have proven the genetic unity of the people living in the current Iranian borders and the lack of influence of Arab and more generally foreign genetics on them. According to the most recent research done by Cambridge Professor Dr. Maziar Ashrafian Bonab, Iranian genetics trace their roots back to the genetics of the people who used to live around Mesopotamia and in current South-West Iran 10,000 years ago.

Culture

The Persians have always considered themselves a people that are substantially different from their Arab neighbors to the South and West, their Russian and Turkish neighbors to the North and their Indian neighbors to the East. They have a culture and a language which are more closely related to English than Arabic or Turkish. They have their own calendar, customs, traditional clothing, food, history (see Persian history) and festivals such as Nowrooz, Chaharshanbeh Soori, Sizdah Bedar, Mehregan, Shabe Yalda.

That should be 'Arab'. The answer is definitely not. Iranians are, for the most part speakers of an Aryan language and originally come from India. There are quite a few Arabs in the south, however.

Answer 2
