Look up S Yokoyama (1991), Molecular evolution of human 
immunodefiniciency viruses and related retroviruses, in: Evolution 
at the Molecular Level, Selander, Clark, Whittam, Eds., Sinauer 
Associates, ISBN 0-87893-818-4.

In order: 400+ years, from monkeys in Africa - and because of 
expanding road transport networks in Africa and air traffic into and 
out of Africa.
