Final answer:
Humans originally migrated from eastern and southern Africa. They first spread within Africa and then to Asia, Australia, Europe, and eventually crossed from Asia to North America, and down to South America.
Step-by-step explanation:
Human Migration Patterns
Humans originally migrated from eastern and southern Africa and expanded their presence to other regions over time. The first areas of migration were within Africa itself, going deeper south, west, and north up to the Mediterranean Sea. Approximately 100,000 years ago, humans crossed the Sinai into southwest Asia, likely following the coastal routes into India and China about seventy thousand years ago.
Some groups continued moving south through Malaysia and into regions like Indonesia and Australia, with settlements evident from at least forty-five thousand years ago. Others moved into Europe around forty thousand years ago, either along the Mediterranean coast or through Turkey into the Danube valley. By twenty-five thousand years ago, Homo sapiens had reached areas including Siberia in northern Asia.
Finally, around fifteen thousand years ago, ancestral humans from Asia crossed into North America, eventually traveling down to the southern tip of South America, and settling various locations in between. The last significant migrations involved settling North and South America, with archaeological evidence showing early human occupations in these continents dating back thousands of years.
