I came across this very insightfull article in all places The Conservative Voice about we as humans being different variations in color and ethnicity coming from the same ancestral parent.
Here's an excerpt:
The Racist German Shepard And Bull Dog
As I was walking down the road the other day I overheard a German Shepherd talking to a bull dog. I over-heard the German Shepherd saying to the bull dog "You can't possibly be a dog because you don't look like me! Why, just look at your flat nose and jaw, your round head, your stumpy neck, and short legs. You look more like a cat than you do a dog! Hey, is that your nose or your mouth? Hahahaha! Do you grow the ugly nappy hair that poodles have? How can anything that looks like you have the soul, intelligence, and feelings of a dog? Who gave you the right to be called a dog? Get out of my sight you ugly looking thing!"
I mention the above illustration to make a point to those who harbor racism. I hope that you will repent of your sin of racism, which is a great sin against God Who created all men in His image and has commanded all men to love one another, and that you will receive the love and forgiveness of God which is in Jesus Christ our Lord and Savior Who paid the penalty for all our sins through His death and shedding of His blood on the Cross of Calvary and Who rose again from the dead to give us eternal life.
Here's another excerpt....
Young people, and even adults, often wonder how all the varieties or "races" of people could come from the same original human ancestors. Well, in principle, that's no different than asking how children with different color hair ( i.e., blond, brunette, brown, red ) can come from the same parents who both have black hair.
Just as some individuals today carry genes to produce descendants with different color hair and eyes, humanity's first parents, Adam and Eve, possessed genes to produce all the variety and races of men. You and I today may not carry the genes to produce every variety or race of humans, but humanity's first parents did possess such genes.
All varieties of humans carry genes for the same basic traits, but not all humans carry every possible variation of those genes. For example, one person may be carrying several variations of the gene for eye color ( i.e., brown, green, blue ) , but someone else may be carrying only one variation of the gene for eye color ( i.e., brown ). Thus, both will have different abilities to affect the eye color of their offspring.
Some parents with black hair, for example, are capable of producing children with blond hair, but their blond children (because they inherit only recessive genes) will not have the ability to produce children with black hair unless they mate with someone else who has black hair. If the blond descendants only mate with other blondes then the entire line and population will only be blond even though the original ancestor was black-haired.
In reality there is only one race - the human race - within which exists myriad variations and permutations. Just as you can get a pure bred from a mutt but not a mutt from a pure bred, so too all varieties of humans were able to come from Adam and Eve our first parents.
All varieties of humans belong to one natural species since all varieties of human beings are inter-fertile, and this is biological proof that we are all descendants of a common human ancestor. This is why the Bible says that God "hath made of one all nations of men for to dwell on all the face of the earth ..." (Acts 17:26, KJV). The Bible clearly teaches that God created all human beings in His image. Therefore, as one of my former pastors, Dr. Carl E. Abrahamsen, Jr., so truthfully and eloquently stated, to hate a fellow human being who has been created in the image of God because of the way he or she looks is a great and serious sin and offense against God which needs to be confessed and repented of before the Almighty.
