This is evolution. I think your statement leaves out some important details. For example there's no guarantee that even if the trait is successful it will be passed onto the next generation because of trait heredity and mating complicatios(mate dies pregnant, cannot find mate, etc.), what does greatly increase chance of inheritance would be a group of animals having that successful trait, thriving in the environment and having offspring. Eventually the trait will become more prominent in the species as the more successful species grows in number from their advantages, the other disadvantaged species may or may not die off depending on whether or not they can migrate to a better environment or if they can still compete with the better species(unlikely). This is natural selection, which is related to evolution.

Evolution can be described as the increase in the amount of individuals in a species inheriting a successful trait over many generations until the evolved population is distinguishable from their ancestors.

So technically RWBY is right, because they said new species of Grimm are being found everyday. Although it must mean that the Grimm rate of reproduction is insane or Grimm are selectively breeding themselves, because it's only been a few years since the Red Trailer and the Beowolves species is already drastically different(assuming that the current Beowolve species is also present where the Red Trailer took place).
