Genetically modified organisms can affect evolution but probably won’t. Variation in the sequences of genes serves as the source for change, i.e. for evolution. However, there must be some change, for example climate change, that selects for those individuals have variants of genes that make them more able to survive and produce offspring under the new climate. If there is no climate change, then those variant genes are lost by simple random mutation. It may take a... Read More

Yes, hair and eye color can be genetically modified. A good example is domestication of animals where both hair and eye color have been selected through breeding which is a form of genetic modification. My wife and I have a pure white, odd-eyed (one yellow and one blue eye), Persian cat. Both her hair and eyes were genetically modified through selective breeding. Genetic engineering is another form of genetic modification. There are multiple... Read More
