My 16,777,216 Grandparents

Pomp can easily become a smug happening when based on miniscule facts. Take ancestors for instance. Lots of people get very pomp about theirs. I wonder if they ever thought about how many direct descendants are bouncing around in their DNA? We all have two parents, which give us four sets of grandparents and eight sets of great grandparents. The math is simple and if everyone will agree that each generation is usually calculated in 20-year increments, then there are five generations in 100 years. Now if that’s so, I have 1,048,576 direct linage grandparents who were getting smitten around 1608. Drop another 100 years and I have 16,777,216 grandparents who were roaming around in 1508 when the world’s population is estimated to have been only 800 million—that’s 2 percent of the population!
