Human Prehistory 101: Epilogue
相關課程
- 500 years ago,
- trans-oceanic travel became a reality.
- Since the end of the last Ice Age,
- farming societies have been absorbing their neighbors,
- making populations more similar within continents.
- That when people began to cross oceans, in large numbers,
- the genetic and cultural differences
- between people from different continents
- also began to fade, though not disappear.
- Many families relocated
- Willingly,
- or unwillingly
- to very distant lands.
- Sometimes, they found unoccupied lands,
- and sometimes they found lands occupied,
- and wished they weren't.
- And sometimes they found land and labor,
- and devised ways of exploiting both.
- All over the world,
- people separated by thousands of kilometers
- for thousands of years
- began meeting once again
- and producing children.
- Today, whole regions, like the Americas,
- are populated by people
- who can trace their ancestry back to multiple continents.
- But some small groups
- are more geographically or culturally isolated,
- and remain genetically distinguishable.
- As long distance transportation gets easier and easier,
- and individual societies become more diverse,
- languages are being lost,
- and genetic distinctions across the globe are fading.
- But these genetic distinctions,
- are a relatively recent phenomenon in our history.
- We haven't been separated for very long.
