evolution
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
Potentially billions and billions of years.
They go round and round the Sun, they have done that for some billions of years and they will continue for some more billions of years.
Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.

This theoretical process is called Macro-evolution, or just "evolution." Some say that this does not occur beyond the microscopic level, others argue that is does. In any case, DNA had to be created before it could change within a life form.
