I have been following the religious debates on News24 for more than 2 years now always having a chuckle at the “religious” trying to wriggle themselves out of uncomfortable questions. Today I would like to pose a question that I have not yet seen here or might have missed.
Some Christians believe the world is only 6000 years old and some believe there was an intelligent designer that set evolution in motion billions of years ago to what we have today. None the less the bible creates a bit of a problem for the different types of ethnic groups.
God said he created us in his image. Fine! Which ethnic group did Adam en Eve belong to and where were they created?
The most recent scientific evidence indicates that all humans evolved in Africa, then populated the rest of the world through successive radiations. It seems likely that the first modern humans had relatively large numbers of eumelanin-producing melanocytes. In accordance, they had darker skin as with the indigenous people of Africa today. As some of these original peoples migrated and settled in areas of Asia and Europe, the selective pressure for eumelanin production decreased in climates where radiation from the sun was less intense. Of the two common gene variants known to be associated with pale human skin, Mc1r does not appear to have undergone positive selection, while SLC24A5 has.
Melanocytes insert granules of melanin into specialized cellular vesicles called melanosomes. These are then transferred into the other skin cells of the human epidermis. The melanosomes in each recipient cell accumulate atop the cell nucleus, where they protect the nuclear DNA from mutations caused by the ionizing radiation of the sun's ultraviolet rays. In general, people whose ancestors lived for long periods in the regions of the globe near the equator have larger quantities of eumelanin in their skins. This makes their skins brown or black and protects them against high levels of exposure to the sun, which more frequently results in melanomas in lighter-skinned people.
The “Out of Africa” theory suggests that humans first started migrating out of Africa between 60 000 and 125 000 years ago according to Arabian archaeology finds of tools in the region.
Let’s say, for argument sake, Adam and Eve where these first people created in Africa that populated the rest of the world and which were dark skinned people. Not to mention the incest and the fact that there is no mention of where Cain’s wife came from, these people had to move to new regions. Mutations started occurring in these people and their appearance started to change. Are these people still in god’s image? Monkeys also resemble human physique to a certain degree and this means you cannot say skin colour and appearance make no difference to what could be interpreted to god’s image, otherwise you say monkeys are made in god’s image as well.
Now here comes the second problem, the great flood. Which ethnic group did Noah and his family belong to and where were they located? If all people on the planet were destroyed and Noah and his family had to start all over again they must have been in Africa and according to the evidence of the first humans they also would have been dark skinned.
Looking at the time melanin needs to change our appearance and the theory by a study into the SLC24A5 gene which found that the allelle associated with light skin in Europe may have originated as recently as 6,000–12,000 years ago, which is in line with the earliest evidence of farming. Noah would not have had the time to send his small family to all corners of the world and re-populate the diverse ethnic groups that we have today in the given time span. This either means that Noah and/or his family left Africa 60 000 to 125 000 years ago, being cave dwellers and only having the most primitive cave man tools at their disposal to create the massive Ark, or this is just some silly story that never happened.
I leave it to you to decide
