Faces of murderers could be recreated from DNA left at crime scenes after science breakthrough

Scientists have identified the genes that shape the extraordinary variation in the human face.

Many features, such as nose size and face width, stem from specific mutations, say researchers.

Previous studies have suggested they are controlled by genes , but this is the first to shed light on how variants contribute to the range of different forms we see.

The findings published in PLOS Genetics may also help researchers to learn how facial birth defects arise.
