I'm writing an essay on the historical evolution of transportation(from packhorse to airplane) and have some questions?
1. When did man start riding horses( all sites i check show me different times like between 3000-2000BC )?
2. Who or what civilisation was first to use the chariot (also when was it invented)?
3. When was the carriage invented and by whom( i've heard the romans did )?
4. When was the first road built?
5. When was saddle/stirrups first used?
6. Finally, when did man start using boats?
Any help is apreciated!
