Fifty years ago Francis Crick and James D. Watson proposed
the double helix model for the DNA molecule.
They believed they had, as Crick put it,
discovered the “secret of life,” and many agreed.
But in the intervening years, science has marched—sometimes leaped—forward,
and now the question “What is life?” must be posed once again.
In this accessible and fascinating book,
Michel Morange draws on recent advances in molecular genetics,
evolutionary biology, astrobiology, and other disciplines
to find today’s answers to the question of life.
