Nose-Shaping Genes in Humans Just Discovered
A multinational team of researchers at the University College London has just identified four genes that determine the shape of a nose. The researchers primarily looked at the width and ‘pointiness’ of noses, which greatly varies in individuals and in different populations. It has long been thought that adaptation to the environment determined the shape of human noses. For example, it is speculated that the cold, dry climate of Europe gave rise to the narrower noses found in European populations.
The researchers analyzed a population of over 6,000 people in Latin America to study the differences in normal facial features.
