Ok. How many people have ever existed in the entire existence of the world? I know many of you will counter by saying it's impossible to know this
number, but an estimate will be used in my logic and calculations. The Population Reference Bureau (sounds official) estimates that 107 billion humans
have ever lived.
What do we assume the average age of one family generation is? I'd say using 25 years would be a very conservative estimate considering teenage
childbirth was far more commonplace thousands of years ago than it is now. Don't forget this number, but we won't need it for now.
Now try to remember all the maths you know. Remember those things called exponentials? You know like X squared and Y to the 7. Yeah that stuff.
How many grandparents do you have? 4? Interesting. Let's see here.
2^2 = 4. Hmmmm so it seems that you if raise 2 to the power of two it will tell you the number of grandparents you have. How many Great great
grandparents do you have? Well each of your 4 grandparents have two parents. 8. Let's check it.
2^3 = 8 - Simply amazing! What is this sorcery? Ok so 2^n means you have [n-2] 'greats' tacked to the title of your ancestors.
So what happens just 37 generations out or [37 x 25 years] = 925 years????? Let's do the Math!
2^37 = 137,438,953,472 (137.44 Billion > the Population Reference Bureau's estimate of only 107 Billion Humans ever living)
But wait a second here Imhotepic you're probably saying to yourself. We've only went back 925 years and we've already exceeded the estimate from the
PRB! Well, to that I say they should improve their estimation techniques, I'm only using math here. I welcome any of you to find flaws in my math or
logic. If anything my estimates are conservative due to my use of 25 as the age of average childbirth and for the age between generations.
How is it a conservative estimate you ask? Let's check the math again.
If I had instead used 16 years as the age of average childbirth throughout the history of mankind the 37 generations required to generate your
[[37-2]/2] great grandmothers and grandfathers would take place in just [37 X 16 years] or 592 years.This is the point at which we would exceed
current PRB estimates of all time ever humans ever to live. Not even 600 years ago when we know humans have been around in some form for at least
100,000 years. At least.
I welcome your responses my brothers and sisters and relatives of all degrees. This was just a nerdy way to make us set aside a few minutes to realize
we each have more than millions of ancestors and that inevitably these ancestors overlap. Don't be fooled by phenotypic expression, we are all one.
Love you brothers and sisters.
