Ever since our forebears learned to walk upright in Eastern Africa nearly four million years ago, voluntary or involuntary migration has been a part of our life. A population that has been separated from its ancestral homeland is considered to have undergone a diaspora. Often these people carry their language and cultural traditions with them to their new location. The earliest historical mention of a diaspora is found in Deuteronomy 28:25, in reference to the Jewish colonies settled outside the holy land following the Babylonian exile.
