Is There a Superior Race?: June 6, 2012
What are the biological differences between different races? Genetic anthropologists have discovered that up to 7 percent of our genes have mutated to new forms in the past 50,000 years. These changes are not just related to skin and eye color, but also to our bones, our digestive systems, and even our brains. Some of these genetic mutations are specific to certain racial groups.
This leads to an unsettling question. Could the brains of different races be different? It's an idea that has spawned war and genocide. But some scientists are daring to probe into our differences. The answers could tell us where the entire human species is headed. One day, pretty soon, we won't have to rely on natural selection to become a smarter species. With advances in genetic technology, we will be able to take matters into our own hands and build a superior race of humans. But genetic technology comes at a cost. Will this create one future race of "haves," and another of "have nots?"
Or will the natural evolution of the brain continue, making our distant offspring far smarter than us? One scientist is testing the limits of the human brain. He thinks the brain is already close to its maximum potential. But another researcher thinks the rapid growth in communication technology will get us all thinking together, forming a giant, global collective mind. If that's the case, there will never be a superior race. But together, we can become a superior species.
