The story of life
10 to 100 million species live on our planet. Every single species – from bacteria, insects and birds, to plants and humans – has a common ancestor. According to Charles Darwin and his theory of evolution, which was published in ‘On the Origin of Species’ in 1859, species evolve thanks to natural selection. The theory explains the basis of kinship between all species. Although it remained controversial for a long time, it has now been largely accepted.
Anti-COVID-19
OAS1: Gene involved in the fight against certain viral infections. A variant of this gene, inherited from Neanderthal, is thought to give protection against COVID-19.

Darwin’s finches
ALX1: Gene which orchestrates the development of our nose, our mouth and our jaw. Genetic analysis of birds collected on the Galapagos Islands showed that this gene has a major effect on the shape of the famous Darwin’s finches’ beaks.

pigmentation
KITLG: This gene is involved in the synthesis of melanin, a pigment found in skin.
phenylketonuria
PAH: This gene is associated with phenylketonuria, a rare genetic disease that prevents phenylalanine metabolism. Babies are tested at birth because excess phenylalanine in the blood can cause mental retardation.
