Facial Reconstruction from DNA
We are all taught in our biology classes that our bodies are built according to a blue print stored in our DNA. Eye color, height, hair curling, everything is in that molecule, and researchers are trying to unlock it. Already we can get at information concerning eye, hair, and skin color from genetic code, but in the future we may be able to build a face from DNA.
Researchers are working to identify the genes responsible for shaping the face and so far five have been identified. While identifying any involved genes is an important step, the researchers admit this is a small step as the total number of genes involved likely numbers in the thousands. These genes are not very powerful on their own, but instead combine together to form the face. For example, one gene does not describe the distance between the eyes, but several contribute, and one of these fives has an effect of just 9 mm on that distance.
There is still a great deal of work to do but the researchers think we may start to see some rudimentary form of facial reconstruction from DNA in less than five years. If that guess is true then this may be the last decade for some books to still be considered science fiction.
