Not so fast

Science News,  June 2, 2007  by Alex Sherer

"Asian Trek: Fossil puts ancient humans in Far East" (SN: 4/7/07, p. 211) "underscores the vast distances" humans moved from Africa to northern China in 20,000 years. However, if one stops to consider the time frames, it's extremely unremarkable. At three generations every 100 years and roughly 6,000 miles from Africa to China, people would need to move only an average of 10 miles per generation. Wow, what travelers!
