What contributed the most to human migration more than ten thousand years ago
Answers
Scarcity of food and lack of shelter, as a result of increase in population, led to human migration. Humans in large numbers migrated, looking for new areas with abundant food supply and shelter.
The early human beings were wanderers. They moved from place to place in search of food and shelter. Later, when they found areas where food was plenty and provided them shelter, they settled down at such places. But with passage of time, the food supplies dwindled and there were others who came looking for it. That was the beginning of human migration.
About 10000 years ago, there occurred an ice age.
This helped human migration in a major way.
Due to the arrival of ice age, large landmasses were formed which covered the seas and connected the different continents.
This allowed the ancient humans to migrate from their origins in Africa and Asia to different parts of the world, thereby promoting human migration
