Fortran->Algol->Cpl->Bcpl->C->C++->Java .....

Seems like every language is built upon an ancestor language. My question : New languages extend parent ones or there is some kind of a trick?

e.g. System.out.print() in Java ; is it actually printf() in C, and so on (printf is actually .. in Cpl)?

If so, doesn't this make every further language be slower and need more memory? What separates a new language from a framework?
