I review evolutionary aspects of general relativity, in particular those related to the hyperbolic character of the field equations and to the applications or consequences that this property entails. I look at several approaches to obtaining symmetric hyperbolic systems of equations out of Einstein’s equations by either removing some gauge freedoms from them, or by considering certain linear combinations of a subset of them.
