How modern globalization is the result of a process of specialization and trade that began at least 8,000 years ago.

Well, people started specializing in things and if they couldn't get something because they didn't know how to make it, they would trade for it. Fast forward 8000 years, companies like Coca Cola make coke and fanta and others can't make it because they're specialized for it. They trade for it with the entire world and other companies make things that Coca Cola owners buy.

This is what i found on google “the first mobile phone call was made 40 years ago today. on april 3, 1973, motorola employee martin cooper stood in midtown manhattan and placed a call to the headquarters of bell labs in new jersey.” i hope this you for what your looking.
