North African Arabs, Albanians, Germans...why are there so many ethnic groups in Italy?

One of the reasons why there are so many ethnic groups in Italy is definitely due to historical migration issues and population fertility. Next, I will focus on analyzing these two reasons in detail.

01. The migration of people in history has caused various foreigners of many non-Italian races to migrate to Italy.

According to expert research data, many foreign races migrated to Italy long ago in the Stone Age. These foreign populations live in Italy, and their genes will remain in Italy, and some genes will also affect the local purebred Italians. Foreigners will continue to migrate to Italy for hundreds of thousands of years. Of course, the number of ethnic groups in Italy will be many and complex.

02. Foreign wives will return to Italy with their Italian husbands to live.

It seems to be a tradition all over the world for women to follow their men to live in their hometown, and Italy is no exception. Many women in Italy come from other ethnic countries and come to Italy to give birth to children for their husbands. Of course, this will change the men's Italian ancestry through the women's foreign genes. This change is very large. After all, it is a gene that has started to change from the initial cell state of human beings. Therefore, this situation has a great impact on the current multi-racial status of Italy.

03. The impact of infectious diseases on Italian genes.

In addition to the above reasons, many external conditions will of course also change Italy's purely racial status. Because of infectious diseases, many people's bodies will develop defense mechanisms, produce certain antibodies, and have a certain degree of resistance to infectious viruses. This situation will further change the body's own genes. With the development of the times and the inheritance of human genes, this resistance gene will also spread and have a certain impact on the Italian purebred genes, but the impact will not be as great as the first two.

The main reason why there are so many foreigners in Italy now is population migration and childbirth.
