THE evolution of humanity has always depended on migration, on those humans determined to risk everything to seek a better life.
From the earliest humans during the Palaeolithic period who, 100,000 years ago, ventured out of Africa and migrated northwards, to modern-day migrants, all without exception demonstrating enormous prowess and initiative in their struggle to escape harsh and intolerable living conditions.
