I have read a couple of the articles here:
http://www.christiananswers.net/race.html but I didn't really understand them. I really am not very good at science and genetics and stuff really confuses me.
Holly, I just went and looked at that article.
I agree it's a bit complex, so I thought I'd try to give a simpler explanation about genetics from my own understanding.
I'm not especially well qualified; just the equivalent of today's GCSE biology, and general nurse training.
However, sometimes it's easier for a not-so-clever person to explain than for an expert to try to simplify, so here's hoping this will help:
If anyone can improve on it please do!
God made the first human pair complete and unspoiled.
God made sure that between the two of them, Adam and Eve held every piece of genetic information which would ever be needed, in order to accomplish His purpose of filling the world with beautifully diverse people; to love Him and each other, and to care for the world in various ways.
Some characteristics are dormant or recessive, so Adam and Eve did not have to display all of these characteristics themselves, they merely carried them.
We are told that they had other children, over a period of several centuries, apart from the named ones.
Each child is unique in their genetic inheritance, as someone has already said.
Ill use red hair for a simplified illustration of how genetic traits are inherited:
Child A
Carries the gene for red hair, as well as genes for other colours.
He has red hair himself.
He is able to pass the gene on to some or all of his own children.
Some of them will have the gene; maybe some of them will have red hair.
Child B
Carries the gene for red hair, as well as genes for other colours.
He has brown hair, yet is still able to pass on the trait for red hair to his children, just as above.
Child C
Does not inherit the gene for red hair at all, only genes for other colours.
He will only pass on the genes he does have, so can't pass on the red hair gene.
None of his children will ever have red hair, unless his wife carries the gene and passes it on to them.
If Child C marries a woman who also has no genes for red hair, they will have no red-haired children.
Some genes have to be present on both parents inorder for a child to receive them, others can be inherited from only one parent.
Suppose a group of families with this (C) and other similar genetic information move away to a remote area, and intermarry for some time.
There will never be any red haired people in that population. Other characteristics will be passed on among them.
This is what we are told happened at Babel different tribes went to different places following the confusion of languages.
Over some years the children of children A and B and C clans will begin to look significantly different from each other.
Red hair is just one over-simplified example of how this might be seen to work.
Imagine all the genetic differences there could have been, even in the first generation after Adam and Eve:
height;
body shape;
colour of eyes, skin, hair;
straight or curly hair;
blood group;
shape of facial features;
all sorts of other things!
As others suggest, there will be an impact by climate on which characteristics thrive in a given area too.
It's not surprising to me that we have great diversity over the earth today.
God bless, Susana
