At the end of March, the insertion of an artificial chromosome in the genome of a yeast confirmed that never before had man reached such a capacity to act on living organisms. And this is only the beginning. Biologists, chemists, anthropologists... are all thinking about these dizzying questions.

"There is no single definition of the living. Chemists don't have the same way of approaching the question as biologists or even astrophysicists," notes Perig Pitrou, deputy director of the nursery and member of the Laboratoire d'anthropologie sociale3 in Paris. Above all, the question of life goes beyond the framework of the so-called hard sciences. For thousands of years, humans have been acting on nature and trying to define life. »
