Race ?

While humanity continues to judge individuals based on arbitrary physical characteristics such as skin, hair or eye color and pretend that combinations of such characteristics constitute different "races" there will be an impediment to social progress. It has long been demonstrated by scientific research that all modern humans in fact belong to the same race and that these physical differences result from minor genetic variations. We are all decended from a population of only a few thousand who lived in Africa around 100,000 years ago at a time when modern humans were in danger of extinction.
To refer then to other individuals as a different race is clearly not correct.
The widely held perception that humans belong to different races is the root of many predjudices that should not exist and have no logical basis. These predjudices are based on primitive "in group out group" insticts and behavior which has also been observed in apes.
Differences in language and culture create the real barriers and we should all work to overcome our predjudices through education and develop tolerance and mutual respect.
