For how many generations has man existed.

Hello yru2l82cataoldotcom,

The figure you seek plus a host of other fascinating statistics
appeared in Harper's Magazine in 1998 in an article by Annie Dillard,
"The wreck of time: Taking our century's measure. Harper's Magazine
296(1772): 51-56. The figures are listed at
http://webhost.bridgew.edu/jhayesboh/Morefood.htm
which is maintained by Dr. James-Kezar IV Hayes-Bohanan who teaches
environmental geography at Bridgewater State College, Massachusetts.

According to these figues, there have been 125,000 generations since
the emergence of the first Homo species, and 7,500 generations of
humans since the emergence of Homo sapiens.  Civilization started only
500 generations ago.  The number of people who have ever lived is
85,000,000,000.

Oops, forgot search strategy:

I searched on Google for: total, generations, human, species,

I like to stump people sometimes.  I gave it my best, but Google came
out smelling like a rose.  I wouldn't have known where to begin -
Amazing
Thank you Google, "I'm hooked" yru2l82cataoldotcom
