"Life emerges from stardust. The first living cell possessed ancestral genes guaranteeing both reproducibility and variability. Thus were created the conditions driving the mechanisms of evolution. This was to lead, in particular, to Human Beings. The genes of the latter mean that their mental capacities include the dual ability to create culture and also to be influenced by it, juxtaposing civilisational evolution with biological evolution. Consequently, Homo sapiens has the capacity to explore the world from which he comes, to question the origins of life, the mechanisms of evolution and his own emergence. Progress made in terms of our knowledge about genes means that this information can be used for medical and biotechnological purposes, thus giving modern man increased power. However, man's genes give him freedom of choice; as a result, this power can be used both for the good and bad of humanity. It is therefore a question of responsibility, questioning to which humans have innate access thanks to exchanges between individuals within the context of a human culture."
