Fortune had been showered upon
you to be living today. Nothing facetious about that whatsoever because today,
as we speak, or rather, as you are reading this musing, consider yourself
one of approximately 7 billion who each comes from a very long line of continuously
unbroken chain of connected lives that span a very, very long time. It is
continuously unbroken because had there been a break, just once, in that chain,
at some point, or any point along that span of tens and thousands of years, you
will not be here.
Here's why. From a set of two people - your parents -
your mother gave birth to you not too long ago.
Before that, two sets of parents (four different people) brought up the
two persons who became your father and mother. You go back another generation
and now we're talking four sets of parents - eight people in all - from your
past who had something to do with you being here. If you go back just a little
bit more, you will count 16, then 32, then 64 who were in that chain in just another
additional three generations. Imagine a very long funnel and you’re at the
bottom tip of it today. Tracing upwards you will have a wall of people lining
the sides of the funnel stretching almost endlessly to an unimaginably flared
top. Markers of your DNA will extend in an unbroken band stretching to however
farther back your imagination will take you.
There is something truly staggering about this, but let's digress for a bit
in the next paragraph.
The Chess Board Story
There are quite a number of different versions of this tale but we’ll
pick one from India since that is where chess likely originated. It’s about a
king, a chess master, who challenged one visitor to a game. The challenger when prompted what he wanted
as a reward after he bested the king, merely asked that a single grain of rice
be put on the first square of the chess board. Two grains on the next, then
doubling that on the third square, which are four grains…then doubling it again
to eight, and so on and on until the 64th square. The king thought
nothing of it and agreed, not realizing that he was faced with the classic
effect of exponentials. Just by the 40th
square there would have been 1 billion grains, but still manageable and well
within what the king had in his vast granaries. The king’s accountants soon
realized that by the 64th square the number of grains of rice
amounted to 18 followed by 30 zeros (1830 grains). That amount of rice would have weighed 210
billion tons, enough to cover all of India with a layer one meter
thick. Assuming just ten grains of rice on a stalk per square inch, a rice
field twice the area of the entire surface of the earth, oceans and lakes
included would have been required for planting.
Two things we learn from that
story: (a)from the second paragraph above, you will see that there had to have
been some serious overlap in our ancestry because there could not have been
that many people to have lived if each individual among 7 billion people today
traces his or her lineage just to one discretely single funnel; (b) often
people, even experts in their field, would use the word exponential, i.e.
exponential growth, profits will grow exponentially, etc., not realizing what
they’re talking about, so tread lightly when using that word, except to use it
metaphorically but often one cannot resist and even add “literally” to it.
To further explain what I just
said from the last sentence, imagine going back just 60 generations before you
were born. The doubling effect of
parents of parents of parents would require an exponential number of people if
we merely account a single line of ancestry.
Therefore, it is only conceivable that a great number of people in every
race and mixed races could trace their ancestry to a relatively much smaller
number of original individuals. Another way is to imagine that you, as an
individual, were at the tip of an ancestral pyramid, which you are, and you
project backwards in time the number of people from whence you came through the
doubling phenomenon of parenting. By the
64th generation the base of the pyramid would exceed the diameter of
the entire solar system if all the people involved with you were from a single
linage if they stood shoulder to shoulder on a straight line.
Therefore, we must conclude that
we all came from a very narrow ancestral base.
All Europeans, for example, have common DNA markers in each and every
one of them, distinctly European, because there had to have been just a handful
of original parents. It is almost as if
there was a proverbial Adam and Eve but mind you, not in the literal
sense. We can say the same for those
from Asia, the Middle East and Africa, of course. People in every race are likely related to
one another and there is more likelihood than not that all races are related as
well. Allow for migration patterns,
allow enough time (as in several thousand years), and allow for the fact that changing
geology dictated climate patterns that dictated the concentration of food and
shelter, biological adaptations, cultural and sociological evolution, etc. the
odds of people mixing, separating, reuniting, exploiting one another through
wars and even local conflicts, and do not forget that we are confined to one
earth –though large and widespread it is still a finite area – the odds of
people “bumping into one another” completes the recipe for the proverbial “melting
pot”. We cannot know all the details but
the math tells us that there could not have been that many people in our
ancestry to have allowed for truly discrete “originals”. I could be wrong but
not by much if we keep in mind that the numbers are not there for you to have
come from a single line without ancestral “entanglements” in the past.
But what has “as luck would have it” got to do with all of what had
been said so far?
Everything! In order to cover every reader we will either
make this about the odds of you making it thus far as just mere fortuitous
results of probabilities or as an acknowledgement that the Creator, as many of
us believe, has a hand in how and why we made it this far; however, God did not
exactly make it that easy for every ancestor.
Just think this through. At any
time along the chain, a break could have occurred because of diseases, famine,
accidents, death through war, enslavement, natural catastrophe, etc. Of course,
either none of those happened or you owe it to your ancestor’s skill, genetics
or luck because you are here now.
The biology of creating you, and
each and every ancestor before you, was always fraught with all kinds of
obstacles. From the moment of conception the struggle for survival, even at the
microscopic level of fertilization, is no picnic for the fertilized egg. Let’s
back up for a bit because before that, anywhere from 40 to 120 million sperm
cells initiated the journey with only a few hundred making it anywhere near the
egg which by comparison is not only a hundred fold bigger than the sperm it is
actually a cellular fortress. As
luck would have it, one sperm cell out of the remaining few hundred will
make it through and the fortress shuts down and fertilization begins. The
fertilized egg must then make an epic journey from the fallopian tube to the
uterus (womb) when at that point it is still considered a foreign body and can
be rejected at any moment. As luck would
have it, the fertilized egg reaches its destination and will cling to the
lining of the uterus like a parasite, which it is, and must remain there for
nine months totally dependent on nutrition from every ancestral mother. Occasionally
the fertilized egg will not get it right and an ectopic pregnancy may occur thus
making the whole journey for naught. Many generations ago under primitive
pre-natal care, or perhaps even none at all, the odds were not too favorable to
the infant or mother. But, as luck would have it, your ancestors
made it and here you are.
Furthermore, as luck would have it, the blueprint of you was intact and followed to the letter throughout your entire
development as an embryo to final term.
Here is the thing. The smallest and
latest computer chip available in the market is phenomenal relative to its
predecessors. It is small and thin all right but we can still clearly see it,
hold it and examine it. It holds a lot of information but not quite as much –
not even close - as the information carried in the fertilized egg. If the egg that is just a mere 100 microns in
diameter (a millionth of a meter) were scaled to the size of a shirt button,
the latest microchip, proportionately scaled, would be about as large as the Houston Astrodome. But, as luck would have it, your mother’s natal
CPU (central processing unit) read all the information correctly so that you
have the right hair and eye color, your limbs were complete, all your organs
developed in the programmed sequence and upon your birth, not only did you
successfully inhale your first mouthful of air outside the womb, you bellowed
with a loud cry that also made your mother cry for joy.
As luck would have it, you and 7 billion others are each at the tip
of unbroken chains of life. But keep in
mind that of all the species that ever lived from since the time life begun
only less than 1% are in existence today.
99% became extinct for many reasons. The fact that our species are still
around is something to behold, and we add to that the reality that our ancestry
had been so entangled in so many ways for so long over eons of time that we
could all be related – one way or the other. Unfortunately, there is a “but” that follows. Because as bad luck would have it, human
frailty and the nature of the human character seems to prevail throughout, from
history to history. If anything, we had proven that human life is
persistent; we persisted on developing, understanding and always aiming to elevate
the human spirit; yet, the most important question still remains unanswered: Why is our history filled with human
conflict, theaters of war in the same battlefields over and over again and again
- our future is pre-dominated by wars and rumors of war?
Hopefully, as luck would
have it, we will somehow find a way
before our luck runs out.
