Studies show that the pre-modern migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appeared to have occupied all of Africa about 150,000 years ago; some members of this species moved out of Africa 70,000 years ago (or, according to more recent studies, as early as 125,000 years ago into Asia, [1] [2 ...
Overview map of the peopling of the world by early humans during the Upper Paleolithic, following the Southern Dispersal paradigm. The so-called "recent dispersal" of modern humans took place about 70–50,000 years ago. [60] [61] [62] It is this migration wave that led to the lasting spread of modern humans throughout the world.
Human migration is the movement of people from one place to another, [1] with intentions of settling, permanently or temporarily, at a new location (geographic region).

Structural functionalists believe that, whether the effects are positive or negative, immigration significantly impacts the level of social cohesion in the workplace.
