What does race have to do with this?

In summary of this article I just read, there is an idea of how we should be grouping people. Is it okay to group people by skin color? Are people of the same skin color actually similar or should they be grouped up with different people? Well, this is a really controversial statement. A way to test how similar people of the same skin color really are is through an experiment. In this experiment, 565 people were used and tested for Alus, pieces of DNA that seem to have no apparent use by are copied over into offspring's DNA. By finding out the how many similarities of Alus people have between them, we are able to figure out exactly how related they are. The results were striking. Typically, the groups were separated into people who's ancestors were isolated from other groups through natural barriers and such. That makes sense though because when people are separated by geological barriers, people tend to change separately resulting in very few similarities in Alus. It's amazing how Africans and Aborigines may have the same skin color, but genetically, are completely different. It's really hard to tell group people into these skin color races because both these cultures developed dark skin in order to adapt from the extreme sun in both Africa and Australia. When attempting to group Indians into their own separate group, scientists found that it was a lot easier grouping Indians with either Europeans or Asians showing that there was a huge European and Asian impact on the country. It's still a very controversial subject about whether we should just group people together by races or not. Some people say that genetic differences are so similar that it is okay to group people into the same race by skin color that it is acceptable to do this. We need to have a clear defined way of grouping people because different groups of people have different reactions to different medicines and diseases and medical companies need to figure out a way to adapt medicine with different people. Good stuff.
