The 'Out of Africa' or 'Eve' concept has intuitively bothered me for three major reasons:
1.Why should we presume Africa as a spacial unit as opposed to say 'Savannahstan'?-a vast region of grassland extending from Asia to Africa millions of years ago.
2.Why should we accept the notion of one way traffic of hominins FROM Africa TO Eurasia?Maybe the early humans ranged thought-out nearly the entire old world-Africa and Eurasia.
3.Absence of evidence is not necessarily evidence of absence.With the discovery of the Dmanisi and Flores fossils I think this point is now clear.How much remains to be found in Eurasia?

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.

JSTOR, the online academic archive, now contains complete back issues of American Scientist from its inception in 1913 (as Sigma Xi Quarterly) through 2005.
The table of contents for each issue is freely available to all users; those with institutional access can read each complete issue.
