The original reference link was dead, and some of the numbers and dates used based on that reference link were wrong. Using two new references, I fixed the dates and removed the dead link. Additionally, I cleaned up the writing a little bit. On the 82.2 seconds of human history figure, I used the conversion rate from the KGS of 146 calendar seconds per year for about 12,000 years (comes out to 12001.2). I hope that doesn't count as "original research", as I wanted maintain some of the previous editor's writing on that.
