Since the genetic material in the first man contained all the characteristics of the various races, parts of this came to dominate in various societies, and thus the human races formed.
5. Why Is The Existence Of Different Races Not Evidence For Evolution?
Some evolutionists try to put the existence of different races forward as evidence for evolution. In fact, this claim is more frequently expressed by amateur evolutionists who have a less than sufficient knowledge of the theory they defend.
The thesis proposed by those who defend this claim is based on the question, "If, as divine sources say, life began with one man and one woman, how could different races have emerged?" Another way of putting it is: "Since Adam and Eve's height, colour, and other features were those of only two people, how could races with entirely different features have emerged?"
In fact, the problem lying beneath all these questions or objections is an insufficient knowledge of the laws of genetics, or the ignoring of them. In order to understand the reason for the differences between the races in today's world, it will be necessary to have some idea of the subject of "variation," which is closely linked to this question.
Variation, a term used in genetics, refers to a genetic event that causes the individuals or groups of a certain type or species to possess different characteristics from one another. The source of this variation is the genetic information possessed by the individuals within that species. As a result of breeding between those individuals, that genetic information comes together in later generations in different combinations. There is an exchange of genetic material between the mother's and father's chromosomes. Genes thus get mixed up with one another. The result of this is a wide variety of individual features.
The different physical features between human races are due to variations within the human race. All the people on Earth carry basically the same genetic information, yet some have slanted eyes, some have red hair, some have long noses, and others are short of stature, all depending on the extent of the variation potential of this genetic information.
In order to understand the variation potential, let us consider a society in which brunette, brown-eyed people predominate over blond, blue-eyed individuals. As a result of the two communities intermingling and marrying over time, new generations which are brunette but blue-eyed will be seen. In other words, the physical characteristics of both groups will come together in subsequent generations and produce new appearances. When one imagines other physical characteristics mixing in the same way, it is clear that a great variety will emerge.
The important point that must be understood here is this: There are two genes that rule every physical feature. One may dominate the other, or they may both influence matters to an equal extent. For instance, two genes determine the colour of a person's eyes. One comes from the mother, the other from the father. Whichever gene is the dominant one, the individual's eye colour will be determined by that gene. In general, dark colours dominate lighter ones. In this way, if a person possesses genes for brown and for green eyes, his eyes will be brown because the brown eye gene is dominant. However, the recessive green colour can be passed down the generations and emerge at a later time. In other words, parents with brown eyes can have a green-eyed child. That is because that colour gene is recessive in both parents.
This law applies to all other physical features and the genes which govern them. Hundreds, or even thousands, of physical features, such as the ears, nose, the shape of the mouth, height, bone structure, and organ structure, shape, and characteristics, are all controlled in the same way. Thanks to this, all the limitless information in the genetic structure can be passed on to subsequent generations without becoming outwardly visible. Adam, the first human being, and Eve, were able to pass the rich information in their genetic structure on to subsequent generations even though only a part of it was reflected in their physical appearance. Geographical isolation that had happened over human history has led to an atmosphere where different physical features came together in different groups. Over a long period of time, this led to different groups having different bone structures, skin colour, height, and skull volumes. This eventually led to the different races.
However, this long period did not change one thing, of course. No matter what their height, skin colour and skull volume, all races are part of the human species.
