Re: [Phys-l] H. Sapiens



I'd like to reprise the population topic briefly (for a change of pace).

Folks seem to have a pretty good set of data that is being fit to exponential form.
I'm reminded of Al Bartlett's many talks and must ask a question.

Based on this exponential curve - about what percentage of the TOTAL historical Homo Sapiens population is currently alive?

This shouldn't be a terribly difficult % to come up with.

thanks for indulging me.
