Our Knowledge of Genetics Severely Limited
Right after the flood, in order for mankind to grow in population, people had no choice but to
marry relatives- that's all there were to choose from! Yet today, we cringe in horror at the thought
of blood related people getting married to each other. Why?
Today, with our new knowledge (which is STILL severely limited) we know that there is
"genetic" material contributed by each parent which gives offspring their characteristics. At this
late date in the "life" of mankind, as well as the animal kingdom, it appears that we have reached
the "dead-end" of the gene-pool; in other words, the possible genetic combinations that can find
their expression in what we term a "species" have all but been exhausted. But there is more to
consider before we think we know it all.
If God is Who we believe He is, then we KNOW He was certainly able to ensure that Noah's
family possessed a gene-pool without flaws, or at least relatively flawless, or else the human race
would not have survived. As they reproduced, this gene-pool thinned out, as we today have every
color of skin, eyes, hair, every shape body from tall to short,- in short, every characteristic of the
human race today had it's beginnings in Noah's family.
Somehow, sometime, defective, or mutated, genes arose. Present day science has shown that
genes mutate due to environmental factors, radiation, certain foods, and other reasons we don't
know about. Genetics is a very complicated subject- but to make the point, we need to understand
only that it's a well-known fact that if 2 people marry, one with a defective gene causing a certain
defect or disease, and one with a non-defective gene, their off-spring have a chance of NOT
inheriting the defect (this is a broad statement, intended only to illustrate a point, which does not
take into consideration "recessive" and "dominant" genes, as well as other more complicated
factors.). But, the defective gene may have been passed on to the child who, although free of the
defect, becomes a "carrier" of that gene and capable of passing it on to it's offspring. Now, if 2
closely related people marry who are from a family with a defective gene, and both are carriers,
the chances are that their off-spring WILL have the defect. Thus, "in-breeding", or marrying
within one's own family, significantly increases the chances of producing children with genetic
defects and illnesses. Albinism, insanity, deaf-mutism and cleft palate were commonly found in
families who had inbred for long periods of time. Finally, sterility and infant mortality is much
higher in these unions than others.
Ok, so why didn't all this happen to Noah's family? Why didn't they all have defects from
in-breeding? The only answer can be that they started out with no defective genes. In order for
mankind to effectively repopulate the earth, God made sure that they could produce healthy
off-spring by providing them with a "clean slate" to start out with. But after an unknown period of
time, if people kept marrying who were closely related, these defective genes would start
crippling the population. We know that God gave specific instructions to the people through
Moses forbidding "kinship" marriages, but the evidence indicates that He also made it known to
the people prior to the dispersion from Babel that it was important for man to marry as far from
his own blood-line as possible. How do we know? Because the earliest civilizations, those soon
after Babel, all had strict laws about incest and marrying within your own family. More on that
later.
But what does this have to do with animals? It tells us that God has set limits or bounds to insure
the diversity of His creation, and also to maintain the purity of that which He created. It also tells
us that He made certain "genetic exceptions and provisions" at the time of the flood that no longer
are valid today. He obviously took great care to insure that mankind, in it's rebirth after the flood,
would have the best genetic material with which to begin. Man, alone, was created in His image.
From the beginning, with Noah's family, the "order" or "family" of man would not branch out into
new species. Although mankind would exhibit various shades of skin color, hair color and texture,
eye color, and size, he would always remain as God created him. And though closely-related
humans risk producing defective offspring, God made special provisions to accommodate the
situation after the flood.
