Nose Shape Gene Inherited from Neanderthals

The shape of our nose is determined by a gene inherited from our Neanderthal ancestors, according to a recent study. The research, published in the journal Science, sheds light on the evolution of human facial features and provides insight into the genetic makeup of modern humans.

Introduction

The study found that a specific gene, known as the RUNX2 gene, is responsible for the shape of our nose. This gene was inherited from Neanderthals, who interbred with modern humans tens of thousands of years ago.

The Role of Neanderthals in Human Evolution

Neanderthals were a species of human that lived in Europe and Asia until about 40,000 years ago. They were closely related to modern humans and interbred with them on several occasions. As a result, many people today carry small amounts of Neanderthal DNA in their genomes.

The RUNX2 Gene and Nose Shape

The RUNX2 gene is involved in the development of bones and cartilage in the face. The researchers found that people who carry a specific variant of this gene have a more prominent nose than those who do not.

Implications for Human Evolution

The study provides new insights into the evolution of human facial features. It suggests that interbreeding with Neanderthals played a role in shaping the physical characteristics of modern humans.

Conclusion

In conclusion, the shape of our nose is determined by a gene inherited from our Neanderthal ancestors. This finding sheds light on the evolution of human facial features and provides insight into the genetic makeup of modern humans.

FAQs

1. How did researchers discover this information about the RUNX2 gene?

- The researchers analyzed genetic data from thousands of people to identify the role of the RUNX2 gene in nose shape.

2. What other physical characteristics might be influenced by Neanderthal DNA?

- Other physical characteristics that may be influenced by Neanderthal DNA include skin color, hair texture, and susceptibility to certain diseases.

3. How much Neanderthal DNA do modern humans typically carry?

- Modern humans typically carry between 1-4% Neanderthal DNA in their genomes.
