This is the data I used to construct my Evolution Timeline, and also for my narrative, Evolution, The Movie.
The numbers have been reduced so that "First Life" calculates to one year ago. The cell is indicated in pink.
Of course, which year it is now, today, means nothing when the number of years is large. When the number of years is small, as in the lower part of the chart, the degree of error gets much more significant.
The dates are as of May, 2002. The cells in which the numbers reach zero are indicated with yellow.
