Great catch—and an essential question for tracing humanity’s journey.
Humans spread into Asia surprisingly early—long before they reached Europe or the Americas. Let’s look at this more precisely:
Timeline of Human Expansion into Asia:
1. Homo erectus in Asia (~1.8 million years ago)
- One of the first hominins to leave Africa.
- Fossils found in:
- Dmanisi, Georgia (~1.8 mya) – oldest evidence of hominins outside Africa.
- Java, Indonesia (~1.6 mya) – Homo erectus survived there until ~100,000 years ago or later.
- These early dispersals were not Homo sapiens, but crucial precursors.
2. Early Homo sapiens in Asia (~100,000–70,000 years ago or earlier)
- The earliest known Homo sapiens fossils in Asia:
- Misliya Cave, Israel (~180,000 ya) – potentially the oldest modern human outside Africa.
- Skhul and Qafzeh Caves, Levant (~120,000 ya) – early but possibly failed expansion.
- Southern China (Zhirendong, Fuyan Caves) – teeth and jawbones dated to ~80,000–100,000 ya.
- Sumatra, Borneo, Philippines – humans were in Island Southeast Asia by ~70,000–60,000 ya.
So:
- Homo sapiens likely entered southern and eastern Asia as early as 100,000 years ago, in multiple waves.
- These populations moved along the coastline (“Southern Dispersal Route”) from Africa via Arabia and the Indian subcontinent, down into Southeast Asia and eventually Australia.
Why Asia First?
- Geographical proximity: Asia is directly adjacent to northeastern Africa (via the Sinai and Arabian Peninsula).
- Climatic corridors: Glacial periods dropped sea levels and exposed land bridges.
- Coastal migration routes allowed early humans to move rapidly along shorelines.
