The theory that living species were descend with changes from other species over time is referred to as evolution.
The process of a species changing over a long period of time is known as a metamorphosis.

It's Evolution
coevolution
This phenomenon is known as coevolution, where changes in one species can drive changes in another species as they interact and exert selective pressures on each other over time.
Divergent Evolution, Convergent Evolution, and Coevolution
Evolution happens over a long period of time, so nothing suddenly changes. Unless you're talking about pokemon. I believe you're thinking of divergent evolution.
Evolution is a change in species over time.
Species not always change over time such sponges :D

Over time species evolve into new species.
The phrase "one species evolving into another" has an unfortunate rate of incidence. It presupposes that there is some "box A" and a "box B", and that lifeforms at some point evolve out of "box A" and into "box B". In reality, there are no boxes. There are just labels that we humans attach to the different shapes we see in life. The way that evolution describes speciation is in terms of continued divergence between populations at the genetic, morphological and behavioural level, occasionally resulting in a significant decline in interbreeding between these populations, after which the reproductively separated populations continue to diverge. When this happens, we say that speciation has occurred, and attach new species-labels to one or both of the resulting populations. Considering this, it would be more appropriate to use the population as a basic unit of evolution than the species.
Evolution is the change in species over long periods of time.
The study of fossils represent the evolution of species by the time period between when they became fossils and what the ancestory line is
A gradual change in life-forms over time is organic evolution.
