Theory of Migration
In the 1880s, Ernst Georg Ravenstein developed a theory of human movement that continues to serve as the foundation for contemporary migration theory.
The following was a standard list after Ravenstein’s (1834–1913) proposal in the 1880s. The theories are as follows:
- Every migration flow generates a return or counter-migration.
- The majority of migrants move a short distance.
- Migrants who move longer distances tend to choose major sources of economic activity.
- Urban residents are often less migratory than inhabitants of rural areas.
- Families are less likely to make international moves than young adults.
- Most migrants are adults.
- Large towns grow by migration rather than natural population growth.
- More long distance migrants are male.
- More long distance migrants are adult individuals rather than families with children.
Homo Sapiens and Early Human Migration
Homo sapiens, the ancestors of modern humans, originated between 200,000 and 300,000 years ago. It is estimated that they first used language 50,000 years ago. The first people began to migrate out of Africa between 70,000 and 100,000 years ago. Humans are unique because no other species that we are aware of has expanded, adapted to, and moved several locations on Earth. This has greatly impacted the ecology and history.
In this article, let us take a deep dive into the early human migration and homo sapiens.
